Rare Birds in The Netherlands in 2001

Roland E van der Vliet, Jan van der Laan & CDNA

This is the 22nd annual report on rare birds in the Netherlands to be published in Dutch Birding. This report comprises records from 2001 as well as belated and reconsidered records, dating back to 1963, which have been evaluated by the Dutch rarities committee, the Commissie Dwaalgasten Nederlandse Avifauna (CDNA). Several 2001 records are still under review or awaiting submission and could, therefore, not be included. In addition, several records for 2000 and earlier years are still under consideration for various reasons.
This report sees the results of three reviews undertaken by the CDNA. In two cases, it referred to records of taxa considered by the CDNA which had been split into two or more species by Sangster et al (1998): field records of Cory's/ Scopoli's Shearwater Calonectris borealis/diomedea and all records of isabelline shrike Lanius arenarius/phoenicuroides/isabellinus. Also, the status of Demoiselle Crane Anthropoides virgo has been a tough nut to crack for several years now. The first result of a review of several records (concerning individuals that were positively observed to be unringed) is presented here. Finally, the CDNA is involved in a review of all records of Subalpine Warbler Sylvia cantillans to determine the subspecies. The first result is presented in this report.
Details included for each accepted record are, if available: date(s); location and/or municipality (municipal divisions as on 1 January 2001); province; number of birds if more than one, plumage and sex; type of record if trapped, photographed, videoed, sound-recorded or found dead (and where specimen is stored); names of up to three observers involved in finding, identifying and recording, and relevant references in the literature, which normally include (inter)national butnot regional journals, and published photographs. Records from 2000 lasting into 2001 that were already published in the 2000 report are repeated here without references, for the sake of completeness. Observations not (yet) submitted mentioned in the 2000 report, are not repeated in this report and the CDNA recommends consulting the 2000 report for these. Sequence of the records in the species accounts is from the current year backwards, with records within one year presented chronologically. A compilation of most of the birds videoed can be found in Plomp et al (2002). Numbers after each (sub)species' name refer to the total number of individuals 1 from 1 January 1800 to 31 December 1979, 2 since 1 January 1980 but excluding 3 the current year. Taxa marked with an asterisk * are new to the Dutch list.
The following CDNA members voted on some or all of the records in this report: Theo Bakker, Max Berlijn, Ruud F J van Beusekom, Ruud E Brouwer, A (Bert) de Bruin (secretary), Nils van Duivendijk (chairman), Jan van der Laan (former chairman), Teus J C Luijendijk, Roland E van der Vliet (archivist) and Pim A Wolf. Records should be sent to CDNA, Postbus 45, 2080 AA Santpoort-Zuid, the Netherlands, preferably using standard forms which can be obtained free of charge from the CDNA. Records can also be submitted through email (cdna@dutchbirding.nl) or via the CDNA site on the Dutch Birding website (www.dutchbirding.nl), using an electronic submission form. On the same site, it is possible to see which records are currently under review, which were recently accepted and which were rejected.
Decisions regarding taxonomy have been delegated to the Dutch committee for avian systematics, the Commissie Systematiek Nederlandse Avifauna (CSNA) which on 1 January 2002 consisted of the following members: Arnoud B van den Berg, André J van Loon, C S (Kees) Roselaar, George Sangster (secretary) and Ronald Sluys.
From 1 January 2002 onwards, the CDNA has decided to again consider records of Parrot Crossbill Loxia pytyopsittacus. This species had not been considered between 1 January 1993 and 1 January 2002, but the CDNA considers it likely that this species has returned to its former rarity status in the Netherlands. Apart from this fact, the CDNA considers that it is still a difficult species to identify and therefore merits consideration (cf Robb 2000).
In 2001, at least 354 species were recorded with one species new to the Dutch list: Egyptian Vulture Neophron percnopterus. From earlier years, three other taxa were added to the Dutch list: Demoiselle Crane (first record in 1991), Moltoni's Warbler S c moltonii (first and only record in 1987) and Daurian Shrike (first record in 1995, followed by individuals in 1996 and 2000). Possible other additions to the Dutch list reported in 2001, Black-browed Albatross Diomedea melanophris (cf Mensink 2001) and Eurasian Crag Martin Hirundo rupestris, are still circulating, while a report of a Little Swift Apus affinis (cf Ebels 2001) has not (yet) been submitted. Further highlights in 2001 were the fourth Laughing Gull Larus atricilla, the fourth Red-flanked Bluetail Tarsiger cyanurus, the fourth Blyth's Reed Warbler Acrocephalus dumetorum, the fourth Dartford Warbler S undata, the fifth White-throated Sparrow Zonotricha albicollis and the sixth Red-eyed Vireo Vireo olivaceus. Also, from 1996, the fourth ever Pine Grosbeak Pinicola enucleator has been accepted.
Furthermore, 2001 saw record numbers of Squacco Heron Ardeola ralloides (equalling 1979), Eurasian Griffon Vulture Gyps fulvus, Pallid Harrier Circus macrourus, Pacific Golden Plover Pluvialis fulva, White-rumped Sandpiper Calidris fuscicollis (equalling 2000), Buff-breasted Sandpiper Tryngites subruficollis, Arctic Warbler Phylloscopus borealis and Rose-coloured Starling Sturnus roseus. Several belatedly accepted records established 2000 as a record year for both White-rumped Sandpiper (equalling the six from 2001) and Radde's Warbler P schwarzi. The winter of 2000/01 was a record winter for Greater Spotted Eagle Aquila clanga. On the other hand, however, no records were accepted for 2001 of Little Crake Porzana parva, Baillon's Crake P pusilla or Greater Short-toed Lark Calandrella brachydactyla.

Systematic list of accepted records

Ross's Goose / Ross' Gans
Anser rossii 0,5,0

1-14 January, Korendijkse Slikken and Nieuwendijk, Korendijk, Zuid-Holland (M Berlijn, M van Dijl et al), and 23 January to 14 February, Workumerwaard, Nijefurd, and Doniaburen and Gaast, Wûnseradiel, and Ferwert, Ferwerderadiel, Friesland (J J F J Jansen et al), and 15 February to 18 March, Anjummerkolken, Dongeradeel, Friesland, and Jaap Deensgat, De Marne, Groningen, adult, white morph, photographed, videoed (T Bakker, A de Bruin, A B van den Berg et al); 16 December, Den Bommel, Oostflakkee, Zuid-Holland, adult, white morph, photographed (H Zevenhuizen, N van Duivendijk, D Kok et al).
2000 31 August to 27 April 2001, Korendijkse Slikken, Korendijk, Plaat van Scheelhoek, Goedereede, and Strijen, Zuid-Holland, and Tonnekreek and Willemstad, Zevenbergen, Noord-Brabant, adult, white morph, photographed, videoed (Birding World 14: 55, 2001, Dutch Birding 23: 106, plate 126, 2001).
1998 14-15 November, Workum, Nijefurd, Friesland, and Oudega, Wymbritseradiel, Friesland, adult, white morph, photographed (S Bernardus, J J F J Jansen et al).
1995 12 November, intermittently to 6 March 1996, Plaat van Scheelhoek, Goedereede, Zuid-Holland, adult, white morph, photographed (J van der Laan, L E Edelaar, G J ter Haar).
All records of the winter 2000/01 are considered to refer to two individuals; dates of that winter have already been reported by van der Vliet et al (2001), but note several additional locations. It was the first time that both birds could be seen together (at Korendijkse Slikken on 1-10 January). The 1998 bird is considered to refer to one of the birds seen during the winters 1999/2000 and later. The 1995-96 record is a date extension of a long-staying individual since the winter of 1987/88.

Greenland White-fronted Goose / Groenlandse Kolgans
Anser albifrons flavirostris 14,19,3

3 January, Polder Arkemheen, Nijkerk, Gelderland, three, adult, two males, one female, ringed with neck bands, inscriptions EJJ, EJS and EJV (D A Jonkers); 26-28 February, Polder Groot Mijdrecht, Ronde Venen, Utrecht, two, adult, and 23 March, Polder Demmerik, Ronde Venen, Utrecht, two, adult, wearing neck band (EJS and EJV) (G Hiemstra); 7 February to 26 March, Polder Achteraf, Loosdrecht, and Oostelijke Binnenpolder, Maarssen, Utrecht, adult, wearing neck band (EJJ), photographed, videoed (H R Russer, K Rozier, G J ter Haar et al).
The three birds were ringed during the same catch, with dark blue neck bands with white inscriptions. Two individuals were later seen at Polder Groot Mijdrecht and Polder Demmerik. On 29 October 2001, these two (EJS and EJV) were located and photographed in a flock of 7663 Greenland White-fronted Geese at Wexford Slobs, Wexford, Ireland, where they were last noted on 31 March 2002. Between 6 and 19 April 2002, the large majority of this group left Wexford to return to the breeding areas. On 27 October 2002, both birds had returned to the Wexford Slobs (Alyn Walsh in litt). This observation indicates that vagrants may return to their usual breeding and wintering areas. The third bird turned up at Polder Achteraf and Oostelijke Binnenpolder and was apparently later seen in Germany in autumn 2001. Several other reports have not (yet) been submitted (cf van Dongen et al 2001).

Ring-necked Duck / Ringsnaveleend
Aythya collaris 5,13,1

10 November, De Bijland, Lobith, Rijnwaarden, Gelderland, female, photographed, videoed (A Poelmans, L J R Boon, E A W Ernens et al; Dutch Birding 24: 61, plate 44, 2002).
Only the second record of a female; the first female was in April 1996.

King Eider / Koningseider
Somateria spectabilis 1,9,0

2000 28 August to at least 21 February 2001, Oudeschild and Oost, Texel, Noord-Holland, adult male, photographed, videoed; 30 August to at least 24 May 2001, 't Horntje, Oudeschild and Oost, Texel, Noord-Holland, second calendar-year to third calendar-year male, photographed, videoed (Dutch Birding 23: 106, plate 127, 110, plate 132,2001).
Both records were already published in van der Vliet et al (2001) but note date extensions.

Falcated Duck / Bronskopeend
Mareca falcata 0,5,0

1998 22 April to 12 June, Ezumakeeg, Dongeradeel, Friesland, male (R Cazemier, T Bakker, O Tol et al).
This male is considered to be the same individual as the bird at Ezumakeeg and nearby Jaap Deensgat, Lauwersmeer, De Marne, Groningen, in May 1994, May-June 1995, May 1996 and May 1998.

American Wigeon / Amerikaanse Smient
Mareca americana 5,31,3

12-15 January, Cornwerd, Wûnseradiel, Friesland, male, videoed (S Bernardus, J Bisschop, J J F J Jansen); 15 January, Cornwerd, Wûnseradiel, Friesland, male, videoed (S Bernardus, E de Weerd); 8 October to 8 November, Uithoornse Polder, Uithoorn, Noord-Holland, male, photographed (R S A van Bemmelen, S Rijnbeek, G J ter Haar et al; Dutch Birding 24: 60, plate 41, 2002).
2000 6 November, Bandpolder, Dongeradeel, Friesland, male, photographed (T Bakker, L Boon, K van Dijken et al); 30 December to 27 January 2001, Oranjeplassen, Maassluis, Zuid-Holland, adult male, photographed.
The latter record has already been published in van der Vliet et al (2001). An average year, at first sight, but no less than 10 reports have not (yet) been submitted (cf van Dongen et al 2001, 2002).

Blue-winged Teal / Blauwvleugeltaling
Anas discors 6,20,1

26-27 May, Prunjepolder, Schouwen-Duiveland, Zeeland, male, photographed (H de Waard, L Boon, C van Rijswijk et al; Dutch Birding 23: 236, plate 267, 2001).
A report from 30 September to 3 October at Lepelaarsplassen, Almere, Flevoland, has not (yet) been submitted (cf van Dongen et al 2001).

Green-winged Teal / Amerikaanse Wintertaling
Anas carolinensis 6,18,3

3-5 March, Hilversumse Bovenmeent, Hilversum, Noord-Holland, male, photographed (R P Sinoo, R van Dijk et al); 1-3 April, Polder Achteraf, Loosdrecht and Oostelijke Binnenpolder, Maarssen, Utrecht, male (G Peterse, H R Russer, K J Eigenhuis et al); 5-6 June, Polder IJdoorn, Durgerdam, Amsterdam, Noord-Holland, male, photographed (F van Groen, E de Bruin, G J ter Haar).
Although these occurrences look typical at first sight, the March and the June records were only the third and second for the respective months.

Cory's/Scopoli's Shearwater / Kuhls/Scopoli's Pijlstormvogel
Calonectris borealis / diomedea 0,3,0

1991 18 May, Camperduin, Bergen, Noord-Holland (N F van der Ham, M O Blijerveld, K Woutersen).
1990 17 September, Camperduin, Bergen, Noord-Holland (N F van der Ham).
1986 29 October, Camperduin, Bergen, Noord-Holland (L Stegeman, I Tempelman).
After the split of Cory's Shearwater into three species (Sangster et al 1998), it was decided to review all three sight records of this species. None of the three descriptions matched the criteria presented by Gutiérrez (1998), although the records remain acceptable as C borealis/ diomedea (Cape Verde Shearwater C edwardsii had already been excluded). There are now four accepted records of Cory's Shearwater, all of birds found dead or dying: in October 1947, November 1966, November 1981 and September 1996. There is as yet no proof that Scopoli's Shearwater has occurred in the North Sea. The 1990 record was erroneously given for 24 September in van den Berg & Bosman (1999, 2001).

Balearic Shearwater / Vale Pijlstormvogel
Puffinus mauretanicus 5,64,-

1994 9 August, Bloemendaal aan Zee, Bloemendaal, Noord-Holland (S C V Geelhoed).
This species is no longer considered since 1 January 1998 but the CDNA welcomes all records before this date.

European Storm-petrel / Stormvogeltje
Hydrobates pelagicus -,115,-

1998 15 September, Bloemendaal aan Zee, Bloemendaal, Noord-Holland (A Gouw, S C V Geelhoed).
1993 16 December, Bloemendaal aan Zee, Bloemendaal, Noord-Holland (S C V Geelhoed).
1992 11 November Bloemendaal aan Zee, Bloemendaal, Noord-Holland (S C V Geelhoed).
1990 31 October, Bloemendaal aan Zee, Bloemendaal, Noord-Holland (S C V Geelhoed).
This species is no longer considered since 1 January 2000 but the CDNA gratefully welcomes all records before this date.

Great White Pelican / Roze Pelikaan
Pelecanus onocrotalus 3,2,2

25 May, Meijel, Limburg, adult (M A H M Sonnemans); 28 May, Oil Platform K-18 Kotter, Continental Shelf, captured, taken into care at Den Helder, Noord-Holland, and handed over to Burgers Zoo, Arnhem, Gelderland, first-summer, photographed, videoed (J Friso, R E Brouwer, R Halff; van der Spek & Ebels 2001; Birding World 14: 234, 2001, Dutch Birding 23: 243, plate 276, 2001).
1975 25 May, Meijendel, Wassenaar, Zuid-Holland (J H Ros, J A de Raad), and Noordwijk, Zuid-Holland, adult (J van Dijk); 5 August, Vlinderbalg, Lauwersmeer, De Marne, Groningen, adult (M R van Eerden, J Prop).
These four records take the total to seven. Previous records were in 1974-75, 1987 and 1990. A bird at Hompelvoet, Zuid-Holland, from 25 June to 14 July 1975 is still under review; it was reportedly accompanied by a Dalmatian Pelican P crispus (which is also still under review).

Squacco Heron / Ralreiger
Ardeola ralloides 25 (since 1866),16,4

24-29 May, Rammegors, Tholen, Zeeland, photographed, videoed (B van den Broek et al; Dutch Birding 23: 232, plate 258, 2001); 27 May, Puiflijk, Druten, Gelderland, photographed (J de Vries; Dutch Birding 23: 232, plate 257, 2001); 9 June, Buurser Zand, Haaksbergen, Overijssel, adult summer, photographed (H Gronert, G Wesseloo, P Knolle et al); 10 June, Hellegatsplaten, Oostflakkee, Zuid-Holland, adult summer (J J Blankert).
The bird at Rammegors was welcomed by many birders, since the last twitchable had been in June 1992, at the very same location.

Glossy Ibis / Zwarte Ibis
Plegadis falcinellus 115,63,-

Eemsmond, Groningen, photographed (A Boven, B-J Prak); 11-20 June, Eemshaven, Eemsmond, Groningen (A Boven, B-J Prak).
In van der Vliet et al (2001), it was erroneously assumed that the same bird was involved in both observations. The observers pointed out, however, that it actually concerned two birds. This species is no longer considered since 1 January 2000 but the CDNA welcomes all records before this date.

* Egyptian Vulture / Aasgier
Neophron percnopterus 0,0,1

24-25 May, Epen, Wittem, Limburg, adult, photographed (H van Oosterhout, M Visser, J Bisschop et al; van Oosterhout 2001; Birding World 14: 187, 2001, 15: 14, 2002, Dutch Birding 23: 241, plate 274, 2001).
A new – but not unexpected – species for the Netherlands. The bird was discovered in the late evening just before sunset and it apparently spent the night near the place of discovery. Next day it re-appeared at 10:00 over a small crowd of lucky birders. Then it disappeared in low clouds and was not found again. A report of an adult later the same day over Krimpen aan den Lek, Zuid-Holland, was not accepted, as was a report of a subadult over Groningen, Groningen, on 12 October.

Eurasian Griffon Vulture / Vale Gier
Gyps fulvus 9,12,20

21 May, Tull en 't Waal, Houten, Utrecht, two (W Stoopendaal); 3 July, Uithoorn, Noord-Holland, and Poelpolder, Lisse, Zuid-Holland, and Polder Hoogeweg and Noordwijk-Binnen, Noordwijk, Zuid-Holland, and Katwijk aan Zee, Katwijk, Zuid-Holland, 4 July, Noordwijk-Binnen, Noordwijk, Zuid-Holland, and Den Haag, Zuid-Holland, and Maasvlakte, Rotterdam,Zuid-Holland, 5-9 July, Westenschouwen, Schouwen-Duiveland, Zeeland, 18, immatures, and 9 July, Roosendaal, Noord-Brabant, and Leende, Heeze-Leende, Noord-Brabant, 14, photographed, videoed, ring read (R van Harten, E Breed, J van der Laan et al; van der Laan 2001; Birding World 14: 276, 2001, 15: 17, 2002, Dutch Birding 23: 221, plate 241, 235, plate 262, 245, plate 277-278, 297, plate 338-339,2001).
2000 6 July, Boeldershoek, Hengelo, Overijssel, photographed (M Alewijnse, M Christenkamp, J Lansink); 5 August, Vrouwenpolder, Veere, Zeeland (E Sanders).
The large flock was one of the greatest birding events of 2001. The 18 birds were discovered independently by three observers, one of them while riding on a train with a speed of 130 km/h. Two birds of this group were colour-ringed, of which one was read (inscription 2H1). It appeared that this bird had been ringed on 14 September 1999 at Logroño, La Rioja, Spain (Alvaro Camiña Cardenal in litt), making the sensation complete. Most seemed to be second-calendar year birds; at least three birds were two years old or older (including the bird of which the ring was read). A report at Zaltbommel, Gelderland, on 22 May is still under review.

Short-toed Eagle / Slangenarend
Circaetus gallicus 3,9,2

17 June to 26 August, Fochtelooërveen, Norg/Ooststellingwerf, Drenthe/Friesland, maximum of two (two birds from 14 July to 17 August), photographed, videoed (J J F J Jansen, M Brandsma et al; Brandsma & van der Horn 2002).
This is the second record of two birds summering together. There are now 12 records involving 14 individuals.

Pallid Harrier / Steppekiekendief
Circus macrourus 5,7,5

12 May, Knardijk, Lelystad, Flevoland, (sub)adult male (L P Heemskerk, W Leurs, R de Haas et al); 17-18 May, Veenzijdse Polder, Wassenaar, Zuid-Holland, second calendar-year, photographed, videoed (A van Gilst, T J C Luijendijk, J W Wierda et al; Dutch Birding 23: 236, plate 266, 2001); 28 September to 8 October, Vlieland, Friesland, juvenile, male, photographed, videoed (F Ossendorp, G J ter Haar, M Berlijn et al; Ossendorp & ter Haar 2001; Birding World 14: 418, 2001, 15: 17, 2002, Dutch Birding 23: 371, plate 422-423, 373, plate 425, 391, plate 454, 2001); 5-10 October, Nolledijk, Vlissingen, and Veere, Zeeland, juvenile (S Lilipaly, R Sponselee, P L Meininger); 20 October, Langevelderslag, Noordwijk (J W Wierda, P Thomas, O Thomas), and Ter Heijde, Monster, Zuid-Holland, juvenile, photographed (R S A van Bemmelen, D Groenendijk, M Scholte).
The best year ever. There was a large influx in Europe in the autumn of 2001, with, for example, at least 76 individuals in Finland and 62 in Sweden (van den Berg 2001). No less than five reports have not (yet) been submitted: at Terschelling, Friesland, on 2 May; Ameland, Friesland, on 12 May; Aalkeetbuitenpolder, Zuid-Holland, on 16 June; Mariahoop, Zuid-Holland, on 5 July; Eemshaven, Groningen, on 5 October; and Apeldoorn, Gelderland, on 25 October (cf van Dongen et al 2001). Three other reports are still under review (at Breskens, Zeeland, on 24 April; on Schiermonnikoog, Friesland, on 13 May; and at Maasvlakte, Zuid-Holland, on 15 June), while a fourth (at Kennemerduinen, Noord-Holland, on 19 October) was only recently submitted and may well have been the same bird as the one already accepted for 20 October. A bird reported at Ibisweg, Flevoland, on 6 May 2000 is also still under review.

Greater Spotted Eagle / Bastaardarend
Aquila clanga 14,6,3

21-24 January, Spookverlaat, Alphen aan den Rijn, Zuid-Holland, juvenile, photographed, videoed (A de Knijff, D J Moerbeek, M Berlijn et al; Bakker 2001; Dutch Birding 23: 115, plate 143-144, 2001, Birding World 15: 17, 2002); 24 January to 13 May, Anjum, Dongeradeel, Friesland (S Bernardus, E de Weerd, M Berlijn et al), and Oude Robbengat, De Marne, Groningen (A B van den Berg, K Sars et al), second calendar-year, photographed (Bakker 2001; Dutch Birding 23: 114, plate 141-142, 2001); 19 October, Itteren, Maastricht, Limburg, juvenile, photographed, videoed (R van de Laak, K Lemmens, M Berlijn et al).16-17-2000 November, Koedijk, Langedijk, and Bakkum, Castricum, Noord-Holland, juvenile, photographed (G Langedijk, T Damm, J Stok et al).
Another good year, taking the total for the winter of 2000/01 to an unprecedented six. The Limburg bird was also seen just across the border in Belgium on 18-19 October (van Dongen et al 2001).

Booted Eagle / Dwergarend
Hieraaetus pennatus 0,7,2

26 September, Oirschotse Heide, Oirschot, Noord-Brabant, pale morph (M A H M Sonnemans); 30 September, Groene Pollen, Terschelling, Friesland, juvenile, pale morph, photographed (A Ouwerkerk; Birding World 14: 418, 2001, Dutch Birding 23: 373, plate 426, 2001).
The second year with more than one. In 2000, there were three records, all of dark morphs. There are now four records of pale morphs (1993, 1996 and two in 2001) and five of dark morphs (1992, 1995 and three in 2000).

* Demoiselle Crane / Jufferkraanvogel
Anthropoides virgo 0,1,0

1991 7-25 May, Beuven, Lieropsche Heide, Someren, Noord-Brabant, and 27 May, Kokmeeuwenweg, Groote Peel, Asten, Noord-Brabant (N Weijsenveld et al).
1992 30 April, Beuven, Someren, Noord-Brabant, and Veluwsedijk, Asten, Noord-Brabant, and 28 May, Beuven, Lieropsche Heide, Someren, Noord-Brabant, and 29 May, Waschven, Strabrechtse Heide, Heeze, Noord-Brabant, and 31 May, Beuven, Someren, Noord-Brabant, and Veluwsedijk, Asten, Noord-Brabant, and 1 June, Veluwsedijk, Asten, Noord-Brabant, and Starven, Lieropsche Heide, Someren, Noord-Brabant, and 2, 6 and 12 June, Veluwsedijk, Asten, Noord-Brabant, and 4 June, Beuven, Lieropsche Heide, Someren, Noord-Brabant, and 8 June, Ringselven, Budel-Dorplein, Cranendonck, Noord-Brabant (J-E Kikkert, F G S M Hieselaar et al).
20 May, Beuven, Lieropsche Heide, Someren, Noord-Brabant, and 22 May to 3 July, Veluwsedijk, Asten, Noord-Brabant, adult, photographed (J-E Kikkert, A Mendoza et al).
1994 1-14 May, Veluwsedijk, Asten, Noord-Brabant (C van Seggelen).
1995 23 April, Beuven, Someren, Noord-Brabant and 23 April to 7 May, Veluwsedijk, Asten, Noord-Brabant, and intermittently from 30 April to 20 July, Groote Peel, Asten, Noord-Brabant (C van Seggelen).
A new species for the Netherlands. All records above refer to one returning individual. This species has a short but stormy history on the Dutch list. First accepted in 1989 (Berlijn 1991), then rejected after review (van den Berg et al 1993). Then again accepted in 1993 (Wiegant et al 1995, van den Berg & Bosman 1999) but again rejected after review (Wiegant et al 1997, van den Berg & Bosman 2001). And now accepted for the third time. The CDNA is fully aware of the fact that Demoiselle Cranes are held in captivity and that there have been several records of proven escapes, which were submitted and rejected. However, since this species is a long-distance migrant, and other countries in Europe have this species on their list, the CDNA decided to accept this record as the first for the Netherlands. It was positively seen that this bird was not ringed. Other reports from 1989, 1998 and 2000 are still under review.

Stone-curlew / Griel
Burhinus oedicnemus -,31,4

8-9 April, Neeltje Jans, Veere, Zeeland, photographed (P L Meininger, N de Schipper, P P de Vries et al); 12 May, Haagse Waterleidingduinen, Wassenaar, Zuid-Holland (A Remeeus); 15 May Coepelduynen, Noordwijk, Zuid-Holland (A Steenvoorden); 26 July, Prunjepolder, Schouwen-Duiveland, Zeeland, photographed (M Berlijn).
2000 3 October, Kooisplek, Vlieland, Friesland (H van Oosterhout, M Visser).
1997 13 May, Kerk en Zanen, Alphen aan den Rijn, Zuid-Holland (W J M Scheres).
Reports at Katwijk, Zuid-Holland, on 5 May and at Kijkduin, Den Haag, Zuid-Holland, on 11 May have not (yet) been submitted (cf van Dongen et al 2001).

Black-winged Pratincole / Steppevorkstaartplevier
Glareola nordmanni 12,14,1

15-16 August, De Slufter, and 18-22 August, Den Hoorn, Texel, Noord-Holland, first-winter, photographed (E van Egmond, A Wassink et al; Dutch Birding 23: 304, plate 344-345, 2001).
Two other reports in August have not (yet) been submitted (cf van Dongen et al 2001). There are now 24 records (involving 27 birds) compared with 16 records (involving 18 birds) for Collared Pratincole G pratincola.

Greater Sand Plover / Woestijnplevier
Charadrius leschenaultii 1,5,1

23-27 June, Oostvaardersdijk, Almere, Flevoland, second calendar-year female, photographed, videoed (L B Steijn, G J ter Haar, M Berlijn et al; van Bemmelen 2001; Birding World 14: 238, 278, 2001, Dutch Birding 23: 231, plate 256, 2001)
This bird belonged to the subspecies group leschenaultii/crassirostris. It was discovered by birders looking for the White-tailed Lapwing discovered shortly before by another group of birders (van Bemmelen 2001)

American Golden Plover / Amerikaanse Goudplevier
Pluvialis dominica 1,11,1

12 October, Anjumer Polder en Lioessenser Polder, Dongeradeel, Friesland (K Sars, R Offereins, O Tol).
The fifth record for October, which proves to be the best month for this species.

Pacific Golden Plover / Aziatische Goudplevier
Pluvialis fulva 9,11,3

7-12 July, Ezumakeeg, Dongeradeel, Friesland, and Oude Robbengat and Jaap Deensgat, Lauwersmeer, De Marne, Groningen, adult summer, photographed (R Cazemier, D Hoekstra, T Bakker et al); 14 July, Workumerwaard, Nijefurd, Friesland, adult summer, photographed (T J C Luijendijk, K de Vries, R Hofland et al); 21-24 July, Oosterend, Terschelling, Friesland, adult summer moulting to winter plumage, photographed (E van Winden, T M van der Have, A Ouwerkerk et al; Birding World 14: 278, 2001, Dutch Birding 23: 304, plate 347, 2001).
In the previous report (van der Vliet et al 2001), Pacific and American Golden Plover had the same number of records after 1980 but now Pacific Golden Plover has taken over, with 14 after 1980, compared with 12 after 1980 for American Golden Plover.

Sociable Lapwing / Steppekievit
Vanellus gregarius 12,27,1

7-24 April, Stompwijk, Leidschendam, Zuid-Holland, adult summer, photographed, sound-recorded, videoed (T J C Luijendijk, B van den Broek, M Berlijn et al; Dutch Birding 23: 168, plate 190-191, 2001).

White-tailed Lapwing / Witstaartkievit
Vanellus leucurus 1,5,1

23 June, De Blocq van Kuffeler, Almere, Flevoland, adult (R S A van Bemmelen, S Rijbeek, M Scholte; van Bemmelen 2001).
This bird was present for just 15 min and, after it had flown, was never seen again (van Bemmelen 2001). Previous records were in 1975, 1984 (two), 1998, 1999 and 2000, although possibly fewer individuals were involved.

White-rumped Sandpiper / Bonapartes Strandloper
Calidris fuscicollis 1,11,6

8 August, Wagejot, and 9-11 August, De Cocksdorp, Texel, Noord-Holland, adult summer, photographed
(A Wassink, P Duin, E Menkveld et al; Dutch Birding 23: 304, plate 346, 2001); 10-13 August, Polder IJdoorn, Durgerdam, Amsterdam, Noord-Holland, adult summer moulting to winter plumage, photographed, videoed (M Zekhuis, L B Steijn, T J C Luijendijk et al); 25 August to 16 September, Ezumakeeg, Dongeradeel,Friesland, adult summer moulting to winter plumage (T M F Kompier, A de Bruin, R Cazemier et al); 4 September, Oude Robbengat, Lauwersmeer, De Marne, Groningen, adult summer moulting to winter plumage, photographed
(T Bakker, O Tol et al); 5 September, Ezumakeeg, Dongeradeel, Friesland, adult summer (D Kuijper, R O Winters, T Bakker et al); 4-5 November, Oude Robbengat and Jaap Deensgat, Lauwersmeer, De Marne, Groningen, juvenile (M A Noback, J J F J Jansen, A de Bruin et al).

The November record was the second juvenile for the Netherlands; the first juvenile was the first for the Netherlands in October 1977. The August 2000 record is additional to one already reported for the same site in van der Vliet et al (2001).

Broad-billed Sandpiper / Breedbekstrandloper
Limicola falcinellus 23,74,5

13 May, Ezumakeeg, Dongeradeel, Friesland, adult summer, photographed, videoed (T Bakker, D J Moerbeek, R O Winters et al); 13-14 May, Eemshaven, Eemsmond, Groningen, adult summer, photographed (W J B Fontijn, R Mulder, J J F J Jansen et al; Dutch Birding 23: 236, plate 265, 2001); 15 May, De Cocksdorp, Texel, Noord-Holland, adult summer (A Wassink, P Duin); 19 May, Ezumakeeg, Dongeradeel, Friesland, adult summer (A Vink, H Vink-Slotboom, W B Janssen); 29 July to 1 August, polder Breebaart, Termuntenzijl, Delfzijl, Groningen, adult (B-J Prak, A Boven).

1999 9 May, Den Oever, Wieringen, Noord-Holland, adult summer (M Scholte, S Rijnbeek, O de Vries).
At least three reports have not (yet) been submitted (cf van Dongen et al 2001).

Buff-breasted Sandpiper / Blonde Ruiter
Tryngites subruficollis 3,11,6

12-16 May, Ezumakeeg, Dongeradeel, Friesland, adult, photographed, videoed (W L Janse, T J C Luijendijk et al; Jansen 2001); 13 May, Eemshaven, Eemsmond, Groningen, adult (P Soper, J J F J Jansen, R Cazemier et al; Jansen 2001); 29 July to 21 August, Prunjepolder, Schouwen-Duiveland, Zeeland, adult, photographed, videoed (J de Bruijn, D Kok, T J C Luijendijk et al); 6-27 August, Eemshaven, Eemsmond, Groningen, adult, photographed (E Klunder, M A Noback, J J F J Jansen et al; Dutch Birding 23: 303, plate 343, 2001); 2 September, Paesens, Dongeradeel, Friesland, juvenile (T Bakker, R Cazemier, J J F J Jansen et al); 5 October, Opmeer, Noord-Holland, juvenile, ringed, photographed (A Slijkerman, F J Koning et al; Koning 2001; Dutch Birding 23: 394, plate 456, 2001).
The best year ever. The two spring birds were seen displaying with their wings held high, a sight normally restricted to the High Arctic breeding grounds! The juvenile at Opmeer was the first to be trapped and ringed in the Netherlands. A report at Makkumerzuidwaard, Friesland, on 15 August has not (yet) been submitted (cf van Dongen et al 2001).

Long-billed Dowitcher / Grote Grijze Snip
Limnodromus scolopaceus 0,15,1

17 February to 9 May and 4 September into 2002, Prunjepolder, Schouwen-Duiveland, Zeeland, adult, photographed, videoed (H Janse, M Janse, W L Janse et al; Janse 2001; Dutch Birding 23: 236, plate 264, 2001).
This may well have been the same bird that was present as the first for Belgium at Het Zwin, West-Vlaanderen, on 16-18 January 2001 (De Smet 2001). A record from 2000 is still under review. The best months to encounter this Nearctic species are May with five records and August with four.

Terek Sandpiper / Terekruiter
Xenus cinereus 1,18,1

15-20 May, Chaam, Alphen-Chaam, Noord-Brabant, videoed (T Goossens, J J Blankert, M Berlijn et al).
A typical date. There are now 20 records, of which 14 in May.

Wilson's Phalarope / Grote Franjepoot
Phalaropus tricolor 6,10,1

30-31 July, Harlingen, Friesland, adult (O Bondesson et al).
This rare Nearctic wader has become less frequent the past decade. The last record was in 1995, which was only the second in the 1990s. Previous records were in 1966, 1968, 1969, 1971, 1975, 1979, 1981, 1985 (three), 1987 (three), 1988 and 1994. Arrival dates are spread evenly from April to October.

Laughing Gull / Lachmeeuw
Larus atricilla 0,3,1

27 October, De Bijland, Lobith, Rijnwaarden, Gelderland, adult winter (A Poelmans, H Sierdsema).
Because this bird was wearing a colour ring on its right leg, it could be ascertained that it concerned the same bird ringed at Zwillbrocker Venn, Nordrhein-Westfalen, Germany, on 1 June 2001; this bird was first seen here on 11 April 2001 (cf Dutch Birding 24: 161, 162, plate 184, 225, 226, plate 251, 2001).

Baltic Gull / Baltische Mantelmeeuw
Larus fuscus 0,10,1

18 December, Paal 6, Vlieland, Friesland, adult, ring read (C Zuhorn).
1999 25 September, Camperduin, Bergen, Noord-Holland, adult, photographed (S Lagerveld, B Lagerveld, N F van der Ham et al).
The 2001 bird was ringed as a nestling at Kerimäki, Mikkeli, Finland, on 7 July 1995 with a white ring (inscription C364). This observation constitutes the first ringing recovery for the Netherlands, on a surprisingly late (early winter) date (cf Hoogendoorn & van Scheepen 1998). The 1999 bird is another bird than an adult seen nearby at Sint Maartenszee, Noord-Holland, on the same date (cf van der Vliet et al 2001).

Ring-billed Gull / Ringsnavelmeeuw
Larus delawarensis 0,6,0

7 September to February 2002, Goes, Zeeland, adult male, videoed (T J C Luijendijk et al).
2000 6 September to at least 14 January 2001, Goes, Zeeland, adult male, photographed (Dutch Birding 23: 110, plate 134, 2001).
These dates concern the long-staying bird first seen in January 1998.

Ross's Gull / Ross' Meeuw
Rhodostethia rosea 1,11,0

1997 8 November, Camperduin, Bergen, Noord-Holland, adult (N F van der Ham).
The fifth record for this popular seawatching spot.

Roseate Tern / Dougalls Stern
Sterna dougallii 3,21,1

17 June, 's-Gravenhoekinlaag, Noord-Beveland, Zeeland, photographed, videoed (M Hoekstein, M Plomp, N van Duivendijk et al; Dutch Birding 23: 234, plate 261, 2001).
This species was recorded annually in 1989-94 (14 records) but with only four records after 1994, it is becoming rarer again. June and July are the best months to see this tern, with 10 and eight records, respectively.

Black Guillemot / Zwarte Zeekoet
Cepphus grylle 31,43,1

22 January, Posthuiswad, Vlieland, Friesland, found dead, leg retained at Zoological Museum of Amsterdam (ZMA) (F Janssens).
2000 24 October, 't Horntje, Texel, Noord-Holland, first-winter, photographed, taken into care at Ecomare, Texel (W Overman)
The Vlieland bird was erroneously reported for 15 February in van Dongen et al (2001).

Eurasian Eagle Owl / Oehoe
Bubo bubo 1,24,3

The pair at St Pietersberg, Maastricht, Limburg, was present all year and raised three young (J J F J Jansen, J-H van Steenis).

Snowy Owl / Sneeuwuil
Nyctea scandiaca 7,7,0

Several records of presumed or proven ship-assisted birds (at Terneuzen, Zeeland, and at Eemshaven, Groningen) in autumn 2001 remain in circulation (cf Verbelen et al 2001).

Alpine Swift / Alpengierzwaluw
Apus melba 7,30,1

10 May, Heesch, Bernheze, Noord-Brabant (R R Smits, A Smits, F J A Smits).
2000 13 May, Libellemeent, Hilversum, Noord-Holland (R P Sinoo).
The 2000 record takes the total for that year to five. Four other reports in 2000 were never submitted
(cf van der Vliet et al 2001).

Little Swift / Huisgierzwaluw
Apus affinis 0,0,0

A report at Lies, Terschelling, Friesland, on 17 May has not (yet) been submitted (cf Ebels 2001). Although photographs were published of this bird (Birding World 14: 238, 2001, Dutch Birding 23: 237, plate 268-269, 2001), the CDNA thinks it is unwise to consider a species new for the Dutch list without having all information available, including a description and an account of the circumstances.

Grey-headed Woodpecker / Grijskopspecht
Picus canus 1,3,0

The male at Oosterbeek, Renkum, Gelderland, since 8 May 2000 was seen again from 2 March to at least 6 June.

Greater Short-toed Lark / Kortteenleeuwerik
Calandrella brachydactyla 3,23,0

2000 10 November, Camperduin, Bergen, Noord-Holland, photographed (D van Dijck; Dutch Birding 22: 54, plate 69, 2001).
The seemingly long primary projection on the photograph (which would not fit this species but rather Lesser Short-toed Lark C rufescens) is a photographic illusion created by a one or two shorter and/or displaced tail feathers.

Red-rumped Swallow / Roodstuitzwaluw
Hirundo daurica 2,45,3

Oostburg, Zeeland (W L Janse, G Troost, E van Winden); 21 May, Schinkelbos, Aalsmeer, Noord-Holland, photographed, videoed (F Ossendorp, G J ter Haar, J van 't Hoff et al; Dutch Birding 23: 237, plate 270, 2001); 5 October, Nollendijk, Vlissingen, Zeeland, adult (S Lilipaly, P L Meininger, R Sponselee et al).
The bird at Aalsmeer was accepted as belonging to the subspecies H d rufula; this is the only subspecies recorded with certainty in the Netherlands. At least four other spring reports have not (yet) been submitted: Grevelingendam, Zuid-Holland, on 4 May; Den Haag, Zuid-Holland, on 9 May; Terschelling, Friesland, on 12 May; and Breskens, Zeeland, on 23 May (cf van Dongen et al 2001).

Olive-backed Pipit / Siberische Boompieper
Anthus hodgsoni 0,9,1

2-5 October, Mariahoeve, Den Haag, and Wassenaar, Zuid-Holland, photographed, videoed (A van Gilst et al; van Gilst 2001; Birding World 14: 416, 2001, Dutch Birding 23: 393, plate 455, 2001).
As the last twitchable bird occurred c 10 years ago, this was the first opportunity for a whole new generation of birders to add this Asian species to their list. Previous records were in October 1987, April 1988, September 1988, October 1990, January-February 1991 (two birds together), October 1991 and October 1998 (two records).

Citrine Wagtail / Citroenkwikstaart
Motacilla citreola 0,13,1

29 April, Tienhoven, Maarssen, Utrecht, male, summer plumage, photographed, videoed (F Schepers, T M van der Have, M Berlijn et al; Dutch Birding 23: 168, plate 192, 2001).
2000 10 April, Breskens, Oostburg, Zeeland, male summer (J-E Kikkert, E Parée).
The 2000 record was the earliest ever in the Netherlands by c two weeks. There are now three records in April, three in May, one in June, two in August and three in September.

Thrush Nightingale / Noordse Nachtegaal
Luscinia luscinia 7,41,1

15 August, Amsterdamse Waterleidingduinen, Zandvoort, Noord-Holland, first-winter, ringed, photographed (T M van Spanje et al).
2000 13-20 May, Swolgen, Meerlo-Wanssum, Limburg, singing, sound-recorded (J Hoogveld, P Palmen).
The 2000 record is the only one for that year but the first for Limburg.

Red-spotted Bluethroat / Roodsterblauwborst
Luscinia svecica svecica 24,36,0

1999 May, Rottumeroog, Eemsmond, Groningen, male, photographed (R Ubels; Edelenbos & Ubels 1999).

Red-flanked Bluetail / Blauwstaart
Tarsiger cyanurus 1,2,1

5 November, Groene Glop, Schiermonnikoog, Friesland, first-winter female, ringed, photographed (H Vonk, H Bouwmeester; Dutch Birding 24: 63, plate 47, 2002).
Of the four records, three were trapped. This much-wanted species seems to appear exclusively on the Frisian Isles. Previous records were in 1967, 1985 and 2000. The first for Belgium was at Blankenberge, West-Vlaanderen, on 25-27 September 2001 (Thoen 2001, Plomp et al 2002, Thoen & De Smet 2002).

Western Black-eared Wheatear / Westelijke Blonde Tapuit
Oenanthe hispanica 3,2,0

A white-throated adult male 'black-eared wheatear' O hispanica/melanoleuca provisionally identified as Western Black-eared Wheatear was photographed at Lies, Terschelling, Friesland, on 11 May (cf Dutch Birding 23: 237, plate 271, 2001). This record is still in circulation to establish the taxon concerned. A paper by Magnus Ullman discussing the identification of both taxa will be published in Dutch Birding before long. On basis of this paper, all previous records of 'black-eared wheatear' (five accepted as Western Black-eared and two as Eastern Black-eared Wheatear O melanoleuca) will be reviewed. There are strong indications that the first-summer male at Aagtekerke, Veere, Zeeland, on 2-4 June 1996 (Klootwijk & Kuijpers 1996, van den Berg & Bosman 1999, 2001; Dutch Birding 18: 154, plate 168, 1996, 20: 157, plate 120, 1998) currently accepted as Western Black-eared actually concerned an Eastern Black-eared (Magnus Ullman in litt).

Desert Wheatear / Woestijntapuit
Oenanthe deserti 1,7,1

13 October, Eemshaven, Eemsmond, Groningen, first-winter male, photographed, videoed (W J B Fontijn, E Koops, L J R Boon et al; Birding World 14: 416, 2001, Dutch Birding 23: 377, plate 434, 2001).
A typical date, constituting the third record for October. November also has three records and December two, while the only spring record was in April.

Eyebrowed Thrush / Vale Lijster
Turdus obscurus 3,4,1

25 September, Oranjezon, Veere, Zeeland, first-winter, ringed, photographed (A Joosse; Dutch Birding 23: 377, plate 435, 2001).
A report from Schiermonnikoog, Friesland, on 13 October 2000 has not been submitted (cf van der Vliet et al 2001).

Cetti's Warbler / Cetti's Zanger
Cettia cetti -,47,2

12 to late October, Amsterdamse Waterleidingduinen, Zandvoort, Noord-Holland, ringed, photographed
(F J Koning et al; Dutch Birding 23: 380, plate 444, 2001); 24 October, Meijendel, Wassenaar, Zuid-Holland, ringed, photographed (M Verrips, W Bleumink).
2000 22 April to at least 11 March 2001, Oostvoornse Meer, Westvoorne, Zuid-Holland, photographed, ringed on 28 June 2000, sound-recorded.
1973 22 May to 2 June, De Doort, Echt, Limburg (W de Veen).
The 2000 record was already mentioned in van der Vliet et al (2001) but note the date extension. The 1973 record also concerns a date extension.

Zitting Cisticola / Graszanger
Cisticola juncidis -,47,-

1995 early July to 24 September, Kroonspolders, Vlieland, Friesland, six (R Rollingswier).
This record concerns a date extension. It seems likely that a breeding attempt took place on Vlieland in 1995 but the CDNA considers this as unproven. This species is no longer considered since 1 January 2001 but the CDNA welcomes all records before this date.

River Warbler / Krekelzanger
Locustella fluviatilis 7,26,1

27 May to 10 June, Leerdam, Gelderland, singing, sound-recorded, photographed, videoed (L van der Kooij, A Brenkman, M Berlijn et al).
A report from Amsterdam, Noord-Holland, on 16-24 June has not (yet) been submitted (cf van Dongen et al 2001).

Melodious Warbler / Orpheusspotvogel
Hippolais polyglotta 2,27,1

19 August, Amsterdamse Waterleidingduinen, Zandvoort, Noord-Holland, first-winter, ringed, photographed (T M van Spanje; contra van Dongen et al 2001).
2000 13-18 June, Kruisbosch, Epen, Wittem, Limburg, singing, sound-recorded (H Steendam, R M van Dongen, M Berlijn et al).
1998 8 June, Strucht, Valkenburg aan de Geul, Limburg, singing (R M van Dongen).
The 2000 record concerns a date extension.

Blyth's Reed Warbler / Struikrietzanger
Acrocephalus dumetorum 0,3,1

17 October, Kennemerduinen, Bloemendaal, Noord-Holland, first-winter, ringed, photographed (H Akkerman, R Geene, C van Deursen et al; Geene et al 2001; Dutch Birding 23: 395, plate 457-458, 396, plate 459, 2001).
The fourth record but the first in autumn. It was the third bird to be ringed in the Netherlands. Previous records were in June 1990 (ringed), June-July 1996 and June-July 1998 (ringed; mixed breeding with Marsh Warbler A palustris).

Booted Warbler / Kleine Spotvogel
Acrocephalus caligatus 0,9,0

1998 27 September, Westkapelle, Veere, Zeeland, photographed (J J F J Jansen, P A Wolf, A van Kleunen et al).
Reports of birds ringed and photographed at Zandvoort, Noord-Holland, on 21 September and at Hasselt, Overijssel, on 22 September are still circulating (cf Dutch Birding 23: 378, plate 440, 380, plate 445, 2001).

Dartford Warbler / Provençaalse Grasmus
Sylvia undata 1,2,1

24-25 March, Maasvlakte, Rotterdam, Zuid-Holland, first-summer, photographed, videoed (S Bot, M Bot, J van Holten et al; Birding World 14: 98, 2001, Dutch Birding 23: 167, plate 188-189, 2001).
Previous records were in April 1959, November-December 1995 and January 1997.

* Moltoni's Warbler / Moltoni's Baardgrasmus
Sylvia cantillans moltonii 0,1,0

1987 23-26 May, 't Wed, Kennemerduinen, Bloemendaal, Noord-Holland, male, singing (E J van Huijssteeden, S C V Geelhoed, J Stuart et al).
The first record of this taxon. The documentation consisted only of a description but the descriptions of both call and song were very convincing (Gabriel Gargallo in litt) and matched those in Shirihai et al (2000) exactly. The observers were not aware at the time of all differences in song and plumage characters between subspecies. This record proves how important it is to keep good field notes of every detail observed, no matter how unimportant it may seem. The results of the review of all other records of Subalpine Warbler will be published in the 2002 report.

Barred Warbler / Sperwergrasmus
Sylvia nisoria 93,110,-

1988 20 September, IJmuiden, Velsen, Noord-Holland, first-winter (H Groot).
This species is no longer considered since 1 January 1993 but the CDNA welcomes all records before this date.

Greenish Warbler / Grauwe Fitis
Phylloscopus trochiloides 6,22,2

1 September, Kroonspolders, Vlieland, Friesland, first-winter, ringed, photographed (H Bouwmeester; Dutch Birding 23: 378, plate 439, 2001); 23-25 September, Lauwersoog, De Marne, Groningen, singing, photographed (R Cazemier, D Hoekstra, T Bakker et al; Dutch Birding 23: 376, plate 432, 2001).
2000 5-10 September, Stuifdijk, Maasvlakte, Rotterdam, Zuid-Holland, singing (S Rijnbeek, M Scholte, D Groenendijk); 9-11 September, De Robbenjager, De Cocksdorp, Texel, Noord-Holland, singing, photographed, sound-recorded (J de Bruijn, H Zevenhuizen, D Kok).
Both 2000 records concern date extensions (cf van der Vliet et al 2001).

Arctic Warbler / Noordse Boszanger
Phylloscopus borealis 2,10,4

13 September, Groene Glop, Schiermonnikoog, Friesland, first-winter, ringed, photographed (U Rijpma, F Tuinstra, C Monkel et al; Dutch Birding 23: 378, plate 438, 2001); 17 September, Kroonspolders, Vlieland, Friesland, first-winter, ringed, photographed (H Linckens, H de Groot, F Lelieveld); 20 September, Kroonspolders, Vlieland, Friesland, first-winter, ringed, photographed (H Linckens, H de Groot, F Lelieveld); 20 September to 1 October, Petten, Zijpe, Noord-Holland, photographed, sound-recorded, videoed (R E Brouwer, L J R Boon, O de Vries et al; Brouwer 2001; Dutch Birding 23: 389, plate 451-452, 2001).
A record year; the best year so far was 1991 with three birds. The Petten bird gave many birders their first opportunity to study this much-wanted Phylloscopus. A 12-day stay is unique; all previous records were of birds not present for more than a day. Except for one in 1997, all other records concerned ringed or dead birds.

Hume's Leaf Warbler / Humes Bladkoning
Phylloscopus humei 2,17,2

28 February to 3 April, Egmond aan Zee, Bergen, Noord-Holland, photographed, videoed (M Plomp, J Stok et al; Dutch Birding 23: 168, plate 193, 2001); 26 October, Kennemerduinen, Bloemendaal, Noord-Holland, sound-recorded (A B van den Berg, M S Robb, F G S M Hieselaar et al).

Radde's Warbler / Raddes Boszanger
Phylloscopus schwarzi 2,14,0

2000 4 October, De Cocksdorp, Texel, Noord-Holland, sound-recorded, videoed (M Adelaar, A Wassink, N van Duivendijk et al); 8 October, Camping Stortemelk, Vlieland, Friesland (H Groot, L Stegeman, R van Splunder).
Of all localities in the Netherlands, Texel and Vlieland have had most records. On both islands, four birds have occurred but Vlieland has three field records, whereas Texel has only one.

Western Bonelli's Warbler / Bergfluiter
Phylloscopus bonelli 5,21,1

18 August, Maasvlakte, Rotterdam, Zuid-Holland, photographed, videoed (D Groenendijk, M van Duin, M Muusse et al).
Two reports, at Hoge Veluwe, Gelderland, on 20 May and at Het Loo, Vaassen, Gelderland, on 26 May have not (yet) been submitted (cf van Dongen et al 2001).

bonelli's warbler / bergfluiter
Phylloscopus bonelli/orientalis 4,5,1

17 August, Amsterdamse Waterleidingduinen, Zandvoort, Noord-Holland, first-winter, ringed, photographed (T M van Spanje et al).

Siberian Chiffchaff / Siberische Tjiftjaf
Phylloscopus collybita tristis -,13,1

25 October, De Geul, Texel, Noord-Holland, singing, sound-recorded (H Blom, A Wassink).
A bird photographed and sound-recorded at Bloemendaal, Noord-Holland, on 23-25 October (cf Dutch Birding 23: 380, plate 443, 2001) is still in circulation. Several others have not (yet) been submitted.

Iberian Chiffchaff / Iberische Tjiftjaf
Phylloscopus brehmii 2,8,1

26 May to 24 June, Belfeld, Venlo, Limburg, singing, photographed, sound-recorded, videoed (W Bonten, P Palmen, M Berlijn et al; Dutch Birding 23: 235, plate 263, 2001).
The bird's territory was exactly on the Dutch-German border; most of the time it stayed on the German side.

Collared Flycatcher / Withalsvliegenvanger
Ficedula albicollis 23,5,1

5-7 May, Lies, Terschelling, Friesland, first-summer male, photographed (N Oosterveen, R Bon, R Terlou et al; Terlou & Ebels 2001; Birding World 14: 235, 2001, 15: 30, 2002, Dutch Birding 23: 173, plate 196, 238, plate 272, 2001).
A typical date. May is the best month to see this striking flycatcher, with no less than 15 records. A bird photographed on Schiermonnikoog, Friesland, on 1 May has not (yet) been submitted (cf Terlou & Ebels 2001).

* Daurian Shrike / Daurische Klauwier
Lanius isabellinus 0,3,0

2000 1-3 October, Noordhollands Duinreservaat, Castricum, Noord-Holland, first-winter, photographed, videoed (I van der Brugge, H S Schekkerman, M Berlijn et al; Plomp et al 2001; Dutch Birding 22: 309, plate 309, 2000).
1996 8-11 December, Lauwersoog, De Marne, Groningen, and Egbert Schuldinkeiland, Dongeradeel, Friesland, first-winter, photographed (P Herkenrath, D G Duff, T Bamberger; de Bruin 1996, van den Berg & Bosman 1999, 2001; Dutch Birding 18: 339, plate 327, 1996, 19: 43: plate 46, 1997).
1995 4 May, De Cocksdorp, Texel, Noord-Holland, adult male, photographed (H van Oosten, A Wassink, R G Bouwman et al; van Oosten & Ebels 1995, Wassink 1996, van den Berg & Bosman 1999, 2001; Birding World 8: 174, 1995, Dutch Birding 17: 129, plate 110, 1995, 18: 130, plate 133, 1996).

Turkestan/Daurian Shrike / Turkestaanse/Daurische Klauwier
Lanius phoenicuroides / isabellinus 0,2,0

1993 21 October, De Hoge Berg, Texel, Noord-Holland (M A Capello, W R L Mahu, E B Ebels et al; Ebels 1993, Capello et al 1994; Dutch Birding 15: 285, plate 20, 1993).
1985 18-19 October, Schorrenweg, Texel, Noord-Holland (P Wouters; Wouters 1996, Dutch Birding 18: 132, plate 134-136, 1996).
The CDNA decided to review all records of isabelline shrike L arenarius/phoenicuroides/isabellinus after the publication of the identification paper by Worfolk (2000). The CDNA could not agree to which taxon, phoenicuroides or isabellinus, these two records belonged. Three other records were considered to be isabellinus (see above), while a sixth record has already been published as phoenicuroides (van der Vliet et al 2001). A detailed paper discussing these decisions is in preparation for Dutch Birding.

Woodchat Shrike / Roodkopklauwier
Lanius senator -,62,2

31 May to 5 June, Rammegors, Tholen, Zeeland, first-summer, videoed (E Sanders, D van de Spoel, J Walhout et al); 23 September, Vebenabos, Veere, Zeeland, juvenile, photographed (P A Wolf, P L Meininger, M Hoekstein).
A report at Maasvlakte, Rotterdam, Zuid-Holland, on 11 May has not (yet) been submitted (cf van Dongen et al 2001).

House Crow / Huiskraai
Corvus splendens 0,10,3

At Hoek van Holland, Rotterdam, Zuid-Holland, numbers had increased to eight in autumn 2001 (A van der Ent et al; Birding World 14: 144, 2001); 10 January to 19 May, Renesse, Schouwen-Duiveland, Zeeland, male, found dead on 19 May, photographed, videoed, sound-recorded, specimen not retained (A B van den Berg, M Scholte, D Groenendijk et al; Dutch Birding 23: 110, plate 133, 2001).
2000 29 October to January 2001, Hoorn, Noord-Holland, photographed.
1999 31 March, 2 April and 17 April, Westduinpark, Den Haag, Zuid-Holland (R van der Vliet, D Laponder, R Messemaker et al).
The CDNA assumes that the Renesse record refers to the bird that had already been present there from 21 November 1994 to at least 17 August 1997 (cf Ebels & Westerlaken 1996). The 2000 record was already mentioned in van der Vliet et al (2001). The 1999 record is considered to refer to one (or more) of the birds ofHoek van Holland. The total of eight birds at Hoek van Holland adds three more individuals to the totals. A report of a ninth bird at this site during the year has not been accepted due to lack of a description, while a report from Texel, Noord-Holland, on 20 December remains in circulation.

Rose-coloured Starling / Roze Spreeuw
Sturnus roseus 21,45,7

18-24 August, Kornwerderzand, Wûnseradiel, Friesland, adult, photographed, videoed (O Tol, A de Bruin, S de Bruin et al); 19-26 August, Kornwerderzand, Wûnseradiel, Friesland, juvenile, photographed (L B Steijn, D M Brinkhuizen, H Lanters et al); 28 September, Maasvlakte, Rotterdam, Zuid-Holland, juvenile (W van Rijswijk); 29-30 September, De Geul, Texel, Noord-Holland, juvenile (A Vink, H Vink-Slotboom); 30 September to 1 October, Westduinpark and Kijkduin, Den Haag, Zuid-Holland, juvenile (V van der Spek, R van der Vliet, J Ruinaard et al); 15 October, Polder Wassenaar, Texel, Noord-Holland, juvenile (A Wassink); 3 December, West aan Zee, Terschelling, Friesland, juvenile, photographed (W A van Splunder, R A van Splunder, N Ramaker).
At least seven in one year is a new record; the best year so far was 1999 with six birds. Remarkably, the juvenile at Kornwerderzand was the earliest juvenile ever (by six days) and the one on Terschelling the latest juvenile ever to be found – although two juveniles found on earlier dates in previous years stayed until 11 December 1975 and 12 December 1997, respectively. No less than six reports have not (yet) been submitted: Hellegatsplaten, Zuid-Holland, from 30 May to 17 June; between Nijmegen, Gelderland, and Venlo, Limburg, on 3 July; Terschelling, Friesland, on 20-21 August; Texel, Noord-Holland, on 1 September; Vlieland, Friesland, on 25 September; and Amsterdamse Bos, Noord-Holland, on 16 December (cf van Dongen at al 2001, 2002). The CDNA would welcome submission of these records.

Red-eyed Vireo / Roodoogvireo
Vireo olivaceus 0,5,1

13 October, Groene Glop, Schiermonnikoog, Friesland, trapped, photographed (B Nijeboer, W Fokker, O Overdijk et al; Dutch Birding 23: 368, plate 419, 2001).
Previous records of this Nearctic species were in October 1985 (two), September 1991, October 1991 and October 1996. Only the 1996 bird was observed in the field; all others were trapped or found dead.

Arctic Redpoll / Witstuitbarmsijs
Carduelis hornemanni exilipes 43,49,4

17 December to 12 January 2002, Zuid-Eierland, Texel, Noord-Holland, maximum of four (one on 17-20 December, three from 20 December to 12 January, four on 29 December), photographed, videoed, sound-recorded (A Wassink, R E Brouwer, M Berlijn et al; Ebels & Wassink 2001; Dutch Birding 24: 72, plate 59-60, 117, plate 100, 2002).
A bird caught on video at Oosterend, Terschelling, on 23 December (cf Plomp et al 2002) is still under consideration.

Two-barred Crossbill / Witbandkruisbek
Loxia leucoptera 37,205,0

A female photographed at De Zilk, Noordwijkerhout, Zuid-Holland, on c 7 October 1963 has been rejected after review (cf van den Berg & Bosman 2001). The CDNA now considers that the photographs of this bird show a White-winged Crossbill L l leucoptera. Although the CDNA assumes that this Nearctic subspecies could conceivably occur in Europe in a natural state, the plumage and behaviour of this particular individual and the circumstances surrounding its capture pointed towards an origin from captivity (Robb & van den Berg 2002).

Pine Grosbeak / Haakbek
Pinicola enucleator 3,1,0

1996 24 March, Melissant, Dirksland, Zuid-Holland, male, photographed (G de Zoete; de Zoete & Meininger 1997; Dutch Birding 24: 96, plate 78, 2002).
The record-influx into southern Scandinavia in the winter of 2000/01 provided several birders an opportunity to study this species closely. Some noted that several birds had very long nails (Jansen & Bouwman 2002). In museums in Scandinavia, also several specimens were found with long nails. With this in mind, the previously rejected record of 1996 was reconsidered by the CDNA. The CDNA is now of the opinion that the long nails of this bird should not preclude its acceptance as a wild bird.

White-throated Sparrow / Witkeelgors
Zonotrichia albicollis 3,1,1

30 April, Rottumerplaat, Eemsmond, Groningen, adult male, singing, photographed (G Kazemir, D Lutterop; Lutterop 2001; Grauwe Gors 29: 128, 2001).
Although not formally submitted, the published evidence - including two photographs on the observers's website (home.wxs.nl/~lutte000) and one in a regional birding journal - was convincing enough to make this record acceptable. Previous records were in September 1967, October 1967, April 1977 and June 1989. These dates are in line with the pattern of occurrence in Britain and Ireland (Dymond et al 1989).

Rustic Bunting / Bosgors
Emberiza rustica 13,48,1

15-19 October, Oosterend, Terschelling, Friesland, photographed (A Ouwerkerk).
2000 12 October, West-Terschelling, Terschelling, Friesland (W Schep, A Ouwerkerk, P Logtmeijer).
Terschelling is apparently the best place to see this bunting in the Netherlands, with 14 records (concerning 17 individuals).

Little Bunting / Dwerggors
Emberiza pusilla 27,62,2

23 September, Petten, Zijpe, Noord-Holland (L B Steijn, H Groot, P Thomas); 28 September, Camping Stortemelk, Vlieland, Friesland (L B Steijn, K de Vries, J Scharringa et al).
2000 9 December, Groene Strand, Westvoorne, Zuid-Holland (W L Janse, F van der Lans, A Linckens).
An average year, although more than 10 reports have not (yet) been submitted (cf van Dongen et al 2001, 2002). The best years were 1990 (eight) and 1995 (nine).

Yellow-breasted Bunting / Wilgengors
Emberiza aureola 3,7,1

11 September, Groene Glop, Schiermonnikoog, Friesland, juvenile, ringed, photographed (U Rijpma, F Tuinstra, C Monkel et al; Dutch Birding 23: 378, plate 441, 2001).
A typical date; there are now eight records in September and one each in July, August and October.

Systematic list of rejected records

This list contains all records not accepted by the CDNA. Records marked with @ were rejected by all committee members in the first or second voting. Most records were rejected because the identification was not fully established (often due to lack of documentation) or when the bird showed signs of captivity, such as dubious rings, excessive wear or aberrant behaviour. Species for which the CDNA unanimously decided that all records refer to birds of captive origin are indicated with *. This includes records of birds of which all ancestors are assumed to be of captive origin (introduced species of British category C).
