Rare Birds in The Netherlands in 2005
Roland E van der Vliet, Jan van der Laan, Max Berlijn & CDNA
This is the 26th annual report on rare birds in the Netherlands to be published in Dutch Birding. This report comprises records from 2005 as well as belated and reconsidered records, dating back to 1890, which have been evaluated by the Dutch rarities committee, the Commissie Dwaalgasten Nederlandse Avifauna (CDNA). Several 2005 records are still under review or awaiting submission and could therefore not be included. In addition, some records for 2004 and earlier years are still under consideration for various reasons.
Details included for each record are, if available: date(s); location and/or municipality (municipal divisions as on 1 January 2005); province; number of birds if more than one, plumage and sex; type of record if trapped, photographed, sound-recorded, videoed 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 but not regional journals, and published photographs. Records from 2004 lasting into 2005 that were already published in the 2004 report (van der Vliet et al 2005) are repeated here without references, for the sake of completeness. Observations not (yet) submitted mentioned in the 2004 report are not repeated in this report and the CDNA recommends consulting the 2004 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 Boon & Slaterus (2006) and Plomp et al (2006). 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 E Brouwer, A (Bert) de Bruin (former secretary), Nils van Duivendijk, Dick Groenendijk, Teus J C Luijendijk, Laurens B Steijn (secretary), Roland E van der Vliet (chairman), Arend Wassink and Pim A Wolf. Records can 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. Records can also be sent by ordinary mail to CDNA, Postbus 116, 2080 AC Santpoort-Zuid, the Netherlands, preferably using standard forms which can be obtained free of charge from the CDNA. On the website, 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 2005 consisted of the following members: Arnoud B van den Berg, André J van Loon, C S (Kees) Roselaar and George Sangster (secretary).
In 2005, at least 357 species were recorded, of which at least two are new to the Dutch list: Eastern Imperial Eagle Aquila heliaca and Killdeer Charadrius vociferus. A record of Purple-backed Starling Sturnus sturninus, another potential new species, is still under review (two previous records, both in 1999, have been regarded as escapes). From previous years, other additions to the Dutch list are Marbled Duck Marmaronetta angustirostris (2004), Western Orphean Warbler Sylvia hortensis and Hornemann’s Redpoll Carduelis hornemanni hornemanni (2003), Eurasian Pygmy Owl Glaudicium passerinum (2002) and Oriental Pratincole Glareola maldivarum (1997). Highlights from 2005 are the second Trumpeter Finch Bucanetes githagineus, the third Northern Hawk Owl Surnia ulula and Calandra Lark Melanocorypha calandra, the fourth White-throated Robin Irania gutturalis and Isabelline Wheatear Oenanthe isabellina, and the fifth Red-necked Stint Calidris ruficollis. 2005 was a record year for Desert Wheatear O deserti with nine records. In contrast, there were no records of vagrants which occurred almost annually in recent years, like American Golden Plover Pluvialis dominica, Sociable Lapwing Vanellus gregarius, Roseate Tern Sterna dougallii or Citrine Wagtail Motacilla citreola.
Reviews in progress involve records of Whistling Swan Cygnus columbianus (regarding identification) and Yellow-headed Blackbird Xanthocephalus xanthocephalus (regarding identification as well as status).
Systematic list of accepted records
Ross's Goose / Ross' Gans
Anser rossii 0,5,1
2-21 January, Bochtjesplaat and Anjumerkolken, Dongeradeel, Friesland, adult, white morph, photographed (R Cazemier, D Hoekstra, T Bakker et al); 2 February to 18 April, Oostvaardersplassen, Almere and Lelystad, Flevoland, and Polder Zeevang, Zeevang, and Oosterpoel, Waterland, Noord-Holland, adult, white morph, photographed (R A van Dijk, D Tanger et al; Dutch Birding 27: 148, plate 187, 2005); 15 March to 29 April, Scherpenissepolder, Tholen, Zeeland, and Goedereede, and Westplaat Buitengronden, Melissant, Dirksland, Zuid-Holland, two (on at least 21-22 March), adult, white morph, photographed (P A Wolf et al); 27 April, Jan Durkspolder, Oudega, Smallingerland, Friesland, adult, white morph, photographed (J Huizenga); 19-22 October, Anjumerkolken, Dongeradeel, Friesland, adult, white morph, photographed (R Cazemier, O Tol et al).
2004 16 October to 21 February 2005, Rammegors and Scherpenissepolder, Tholen, and Yerseke, Reimerswaal, Zeeland, and Ouddorp, Goedereede, and Slikken van Flakkee, Dirksland, Zuid-Holland, adult, white morph, photographed.
On 21-22 March, three birds were simultaneously present in the Netherlands, which means that a presumed new bird had arrived, adding one bird to the totals.
Canvasback / Grote Tafeleend
Aythya valisineria 0,1,0
14 October to 8 November, Castricum aan Zee, Castricum, Noord-Holland, adult male, photographed, videoed (J Vroege, H Levering, R E Brouwer et al; Dutch Birding 27: 431, plate 540, 2005).
This is considered to be the returning bird first seen in January-March 2003 (Reijnders & Ebels 2004, van der Vliet et al 2004). It was not present (or, at least, not observed) in the winters of 2003/04 and 2004/05.
Ring-necked Duck / Ringsnaveleend
Aythya collaris 5,18,3
22 October to 22 January 2006, Budel-Dorplein, Cranendonck, Noord-Brabant, two (second bird from 29 October), first-winter female, photographed, videoed (R G Bouwman, H Verdaat, F Neijts et al; Dutch Birding 27: 431, plate 539, 2005); 4-6 December, Genne, Hasselt, Overijssel, adult female, photographed (D van de Zee, H B Bouman, G Veurink et al; Dutch Birding 28: 57, plate 75, 2006).
Remarkably, all three birds this year were females. Only two previous records concern females, in April 1996 and November 2001.
King Eider / Koningseider
Somateria spectabilis 1,10,1
14 March, Camperduin, Bergen, Noord-Holland, adult male (G J de Haan, N F van der Ham).
Previous records were in May 1975, December 1981 to March 1982, April 1989, October 1989 to April 1991 (two), March 1993 to May 1995, October-November 1994, May-December 1999, August 2000 to July 2001 (two) and May-September 2003. Only three records refer to females: in April 1989, March 1993 to May 1995, and October-November 1994.
Surf Scoter / Brilzee-eend
Melanitta perspicillata 3,13,3
13-14 March, Buren, Ameland, Friesland, two, adult male, photographed (M S J Hoekstein, P A Wolf, H Verdaat et al; Dutch Birding 27: 222, plate 271, 2005); 6-11 April, Brouwersdam, Schouwen-Duiveland, Zeeland, adult male, photographed (P A Wolf, P L Meininger, S J Lilipaly et al; Dutch Birding 27: 222, plate 272, 2005).
2004 6 November, Camperduin, Bergen, Noord-Holland, adult male (N F van der Ham, S van Kasteel, S Tambach et al).
Reports on the Continental Shelf on 23 November and at Camperduin and Petten, Noord-Holland, on 6 December are still in circulation. The bird at Brouwersdam was possibly the same as the first-winter male present at the same site from 18 January to 7 February 2004 (cf van der Vliet et al 2005) but was accepted as a different bird because, presumably, more than one Surf Scoter can be found in winter in the North Sea area
Bufflehead / Buffelkopeend
Bucephala albeola 0,0,0
A first-winter male (or more than one bird) at various sites between 5 November 2004 and 18 May 2005, and returning the next winter, remains in circulation to determine the status.
Falcated Duck / Bronskopeend
Mareca falcata 0,7,2
26 February to 2 March, Roelofsput, Twenteland, Overijssel, adult male, photographed (R Gerritsen et al; Dutch Birding 27: 148, plate 184, 2005); 26 March to 5 May, Nuldernauw, Putten, Gelderland, adult male, photographed (R O Winters, M Berlijn et al; Birding World 18: 148, 2005, Dutch Birding 27: 222, plate 273, 2005). The male at Nuldernauw was reportedly seen on the other side of the Nuldernauw at Zeewolde, Flevoland, into June but the CDNA did not (yet) receive details.
American Wigeon / Amerikaanse Smient
Mareca americana 5,43,1
3-10 April and 27-30 November, Gaarkeuken, Zuidhorn, Groningen, adult male, photographed (S Norrby, R Cazemier, M Bot et al; Dutch Birding 27: 222, plate 274, 2005).
2004 19 November to 1 February 2005, Heerpolderweg, Schelphoek and Middelplaten, Goes, Zeeland, first-winter male, photographed. 2002 6-16 April, Kollumerwaard, Kollumerland en Nieuwkruisland, Friesland, adult male, photographed (R Cazemier, D Hoekstra, S Bernardus et al).
Note the date extension for the long-staying 2004-05 bird (cf van der Vliet et al 2005). Other reports, eg, near Emmapolder, Groningen, on 18 September and near Sint-Maartensvlotbrug, Noord-Holland, on 2-3 October, have not (yet) been submitted (cf van Dongen et al 2005).
Blue-winged Teal / Blauwvleugeltaling
Anas discors 6,27,0
18-22 April, De Geul and Groote Vlak, Texel, Noord-Holland, adult male, photographed (P Duin, V Stork, J Witte et al).
2004 31 March, Camperduin, Bergen, Noord-Holland, adult male (N F van der Ham).
2003 15 April, Camperduin, Bergen, Noord-Holland, adult male (N F van der Ham).
The 2005 bird is considered to be the returning 2004 bird that was seen at the same site on Texel (cf van der Vliet et al 2005). Both birds at Camperduin in 2003 and 2004 were fly-bys seen during seawatching and therefore not considered to refer to the same individual. A report on 3 May at Camperduin, Noord-Holland, is still in circulation.
Baikal Teal / Siberische Taling
Anas formosa 8,0,0
The bird collected at Damwoude, Friesland, on 29 November 1948 concerns a female, probably an adult, instead of a first-year male as stated in van IJzendoorn et al (1996) and van den Berg & Bosman (1999, 2001). Re-examination of additional photographs of a presumed Baikal Teal at Broekhuizenvorst, Limburg, from 25 December 1994 to at least 8 April 1995 resulted in its re-identification as a hybrid resembling Baikal Teal (cf Br Birds 88: 269, plate 268, 1995, Dutch Birding 17: 34, plate 31, 1995). This bird had previously been accepted regarding identification but was presumed to have been an escape based on its tame behaviour (Wiegant et al 1996, van den Berg & Bosman 1999, 2001).
* Marbled Duck / Marmereend
Marmaronetta angustirostris 0,1,0
2004 14-16 August, Klompenwaard, Doornenburg, Bemmel, and Pannerden, Rijnwaarden, Gelderland, juvenile, photographed, videoed (R O Winters, H van Diek, P Palmen et al; Winters 2004; Birding World 17: 328, 2004, Dutch Birding 26: 346, plate 491, 357, plate 512-513, 2004).
The first record of a presumed wild bird. Its acceptance was aided by the apparent northward dispersal of (especially) juveniles of this species to north-eastern Spain and southern France in late summer.
Balearic Shearwater / Vale Pijlstormvogel
Puffinus mauretanicus 5,67,-
1996 24 July, Westkapelle, Veere, Zeeland (M S J Hoekstein).
This record was previously lost in the mail, so the CDNA is happy that it has finally been accepted. This species is no longer considered since 1 January 1998.
Atlantic Great Cormorant / Grote Aalscholver
Phalacrocorax carbo carbo 6,11,0
2003 27 December, Heel, Limburg, male, adult, summer plumage, colour-ring read, photographed (P Palmen).
2002 17 November, Heel, Limburg, male, adult, summer plumage, colour-ring read (J Vrehen).
2001 4 November, Heel, Limburg, male, adult, summer plumage, colour-ring read (J Vrehen).
2000 4-15 February, Heel, Limburg, male, adult, summer plumage, colour-ring read, photographed, sound-recorded (A McGeehan, A B van den Berg, A J van Loon et al; van den Berg et al 2000; Dutch Birding 22: 22, plate 21-22, 2000), and 16 September to 7 January 2001, Heel, Limburg (J Smeets, J Vrehen); 26 February, Zuidpier, IJmuiden, Velsen, Noord-Holland, immature, photographed (D J Moerbeek); 7 April, Zuidpier, IJmuiden, Velsen, Noord-Holland, three, immature, photographed (D J Moerbeek).
1998 6 September, Heel, Limburg, second-year, colour-ring read, photographed, sound-recorded (T Cuypers; cf van den Berg et al 2000). The annually returning Heel individual was colour-ringed (orange with black markings AX on its left leg) as a chick in a colony at Abberton Reservoir near Colchester, Essex, England, on 3 May 1997 (cf van den Berg et al 2000). This is a mixed colony where both (nominate) Atlantic Great Cormorant and Continental Great Cormorants P c sinensis breed. Because the identification criteria to separate the two taxa were not yet firmly established at the time, the CDNA decided not to accept it as Atlantic Great (cf van der Vliet et al 2001). Since then, however, Newson et al (2004) published a set of identification criteria, after which the CDNA decided to recirculate and accept the Heel bird, as well as the four IJmuiden birds; the latter four are the first birds without colour-rings to be accepted.
Squacco Heron / Ralreiger
Ardeola ralloides 25 (since 1866),34,2
15 June to 2 July, Oostvaardersplassen, Almere, Flevoland, adult, summer plumage, photographed (P Julsing, A Vink et al); 1-2 July, Alblasserdam, Zuid-Holland, adult, summer plumage, photographed (L Tukker, C van Rijswijk et al; Dutch Birding 27: 354, plate 432, 2005).
2003 7 June, Quackjeswater, Westvoorne, Zuid-Holland, adult, summer plumage (H Janse, W L Janse, B Brieffies et al). With the additional record for 2003, this is now the best year since 1866 with seven individuals (cf van der Vliet et al 2005).
Glossy Ibis / Zwarte Ibis
Plegadis falcinellus 116,63,-
1935 September, Zevenaar, Gelderland, collected (A E M van Nispen; cf Lensink 1993).
The year was erroneously given as 1936 in van den Bergh et al (1979) (Jan van der Brugge in litt, Henk Tamerius in litt). This species is no longer considered since 1 January 2000.
Eurasian Griffon Vulture / Vale Gier
Gyps fulvus 9,54,1
22-23 June, Zuid-Eierland, Oosterend and Polder Waal en Burg, Texel, and 23 June, Den Helder, Noord-Holland, immature (A Wassink, P Duin, R E Brouwer et al).
Reports at Oosterbeek, Gelderland, on 24 June and at Heerhugowaard, Noord-Holland, on 10 July have not (yet) been submitted (cf van Dongen et al 2005).
Short-toed Eagle / Slangenarend
Circaetus gallicus 3,20,4
17-22 June, Deelensche Veld, Ede, Gelderland, photographed (A Vink, W Janssen, D Groenendijk et al; Dutch Birding 27: 284, plate 344, 2005); 28 June, Strabrechtse Heide, Someren, Noord-Brabant (R G Bouwman); 2 July to 18 August, Fochteloërveen, Ooststellingwerf, Friesland, and Norg, Drenthe, immature, photographed (A de Bruin, R Cazemier, P van Wetter et al; Dutch Birding 27: 356, plate 437-438, 2005); 31 August, De Wijert, Groningen, Groningen (A van der Spoel).
2002 20 May, Beusichem, Amerongen, Gelderland, immature (A Linckens, W L Janse, F van der Lans et al).
Several reports are still in circulation. Others have not (yet) been submitted (cf van Dongen et al 2005): at Halfweg, Noord-Holland, on 21 May; De Logt, Noord-Brabant, on 22 May; Reeuwijkse Plassen, Zuid-Holland, on 27 May; Marnewaard, Groningen, on 29 May; Naarden, Noord-Holland, on 9 June; Alkmaar, on 26 June; Maastricht, Limburg, on 9 July; Enspijk, Gelderland, on 10 July; Hoge Veluwe, Gelderland, on 12 July; Knardijk, Flevoland, on 23 July; Almere, Flevoland, on 1 August; Lauwersmeer, Groningen, on 17 August; and Dronten, Flevoland, on 13 September.
Pallid Harrier / Steppekiekendief
Circus macrourus 5,19,3
29-30 March, Sint Laurens, Middelburg, Zeeland, third calendar-year or adult male, photographed, videoed (A van Gilst, N de Schipper, M Berlijn et al; Dutch Birding 27: 223, plate 276, 2005); 21 April, Breskens, Oostburg, Zeeland, second calendar-year male, photographed (M Veldt, I Meulmeester et al; Dutch Birding 27: 223, plate 275, 2005); 24 June, Alkmaar, Noord-Holland, adult male (N F van der Ham).
There were no previous records for March and June. Before 2005, records date from 9 April to 17 May in spring and 23 August to 19 October in autumn. Four reports are still in circulation: at Ruurlo, Gelderland on 30 April; Eemshaven, Groningen, on 27 May; Goudzwaard, Zuid-Holland, on 28 August; and Driebergen, Utrecht, on 13 September. Several reports have not (yet) been submitted (cf van Dongen et al 2005): at Posterholt, Limburg, on 26 March; Kamperhoek, Flevoland, on 30 March; Groningen, Groningen, on 4 April; Eemshaven, Groningen, on 11 and another on 25 April; Hoogkerk, Groningen, on 22 April; Sellingen, Groningen, on 2 September; Biggekerke, Zeeland, on 3 September; and Oosternijkerk, Friesland, on 7 September.
Long-legged Buzzard / Arendbuizerd
Buteo rufinus 1,2,0
A bird photographed near Burgh-Haamstede, Zeeland, on 3 October (cf Dutch Birding 27: 431, plate 535, 2005) is still in circulation.
Lesser Spotted Eagle / Schreeuwarend
Aquila pomarina 3,3,1
24-25 September, Domburg, Westkapelle, Oostkapelle and Grijpskerke, Veere, Zeeland, juvenile, photographed, videoed (T Luiten, P Beeke, N de Schipper et al; Luiten 2005; Birding World 18: 373, 2005, 19: 25, 2006, Dutch Birding 27: 427, plate 528-530, 2005).
Only the second twitchable bird (the other was in November 1984). Found on a Saturday evening, it stayed overnight and could be observed the next day by c 200 birders at close range, mainly in flight. Around noon, it disappeared and was not seen again.
Greater Spotted Eagle / Bastaardarend
Aquila clanga 15,12,0
1957 18 August, Lettele, Diepenveen, Overijssel, immature, collected, skin retained at Brabants Natuurmuseum, Tilburg, Noord-Brabant.
This record was erroneously published for 1959 in van der Vliet et al (2005). The museum label indicates that it originates from 1957.
Booted Eagle / Dwergarend
Hieraaetus pennatus 0,13,1
20 May, De Hamert, Arcen en Velden, Limburg, pale morph, photographed (P Palmen).
2004 1 May, Boshoverheide, Weert, Limburg, and Loozerheide, Cranendonk, Noord-Brabant, pale morph, videoed (R Verbraak, F Neijts, N van Houtum et al).
The following five reports have not (yet) been submitted (cf van Dongen et al 2005): at Kennemerduinen, Noord-Holland, on 14 May; Hoogkerk, Groningen, on 27 May; Deelensche Veld, Gelderland, on 1 June and another on 15 June; and Veenendaal, Utrecht, on 12 October.
* Eastern Imperial Eagle / Keizerarend
Aquila heliaca 0,0,1
3 April, Kamperhoek, Dronten, Flevoland, third calendar-year, photographed (R F J van Beusekom, R Alma, M Roos et al; van Beusekom 2005; Birding World 18: 149, 2005, Dutch Birding 27: 233, plate 290-291, 2005).
The bird was observed by seven birders when flying north over the (now) famous migration observation post at Kamperhoek.
Gyr Falcon / Giervalk
Falco rusticolus 4,3,0
2004 13 November, Holwerd, and 19-20 December, Tibma, Dongeradeel, Friesland, juvenile, photographed.
Already published in van der Vliet et al (2005) but mentioned here because the CDNA has decided that only one individual was involved.
Baillon's Crake / Kleinst Waterhoen
Porzana pusilla 88,35,6
20-28 May, De Tjamme, Beerta, Winschoten, Groningen, singing, photographed, sound-recorded, videoed (B-J Prak, M Bot, W Hartholt et al); 30 May to at least 18 August, Polder Achteraf, Loosdrecht, Wijdemeren, Noord-Holland, at least three, adult, singing, photographed, sound-recorded (G van Duin, M Veldt, H R Russer et al; Constantine & The Sound Approach 2006); 3 June to at least 12 August, Nieuwe Keverdijkse Polder, Naardermeer, Naarden, Noord-Holland, at least two, singing, sound-recorded (R F J van Beusekom, M S Robb).
Successful breeding was reported at both Polder Achteraf (cf Constantine & The Sound Approach 2006) and Nieuwe Keverdijkse Polder but the outcome has not been submitted to the CDNA, so no young have (yet) been added to the totals. A report at Weerribben, Overijssel, on 18 June, has not (yet) been submitted (cf van Dongen et al 2005). New information indicates that both males and females have an advertisement call, which differs between the sexes. As the ultimate evidence has not been published, the CDNA now considers it unwise to sex recorded birds.
Stone-curlew / Griel
Burhinus oedicnemus -,44,3
24 April, Meijendel, Wassenaar, Zuid-Holland (A Remeeus); 2 May, Balgzand, Anna Paulowna, Noord-Holland, photographed (R W M Klasens, B Schricken); 6 August, Swifterbant, Dronten, Flevoland, first-winter, photographed, videoed (R Alma, O de Vries, M Plomp et al; Dutch Birding 27: 354, plate 431, 2005).
A report on Terschelling, Friesland, on 5 May, has not (yet) been submitted (cf van Dongen et al 2005).
* Oriental Pratincole / Oosterse Vorkstaartplevier
Glareola maldivarum 0,1,0
1997 1-5 August, Workumerwaard and Doniaburen, Wûnseradiel, Friesland, first-summer, photographed, videoed (M Zekhuis, E Nieuwstraten, G Driessens et al; Nieuwstraten & Zekhuis 1997; Birding World 10: 290, 1997, Dutch Birding 19: 201, plate 204, 211, plate 218-219, 1997).
Although originally identified and submitted as Oriental Pratincole (cf van den Berg & Bosman 1999), it was accepted, after long debates, as an adult Collared Pratincole G pratincola(Wiegant et al 1999, van den Berg & Bosman 2001). A record of an Oriental at Ängsnäset, Falsterbo, Skåne, Sweden, from 2 July to 6 October 2001 created renewed interest in the ‘Doniaburen pratincole’. Several identification features were critically investigated (cf Driessens & Svensson 2005), resulting in the recirculation of the record. After again long debates and, amongst others, delays by files getting lost in the mail, it was not until 2006 when the bird finally was accepted as Oriental, the first for the Netherlands and, by then, the eighth for the Western Palearctic. A paper discussing this bird will be published in Dutch Birding before long.
* Killdeer / Killdeerplevier
Charadrius vociferus 0,0,1
3-5 April, Rottige Meente, West-Stellingwerf, Friesland, and Ossenzijl, IJsselham, Overijssel, second calendar-year, photographed, sound-recorded, videoed (R-J van der Leij, H Brandsma, E B Ebels et al; van der Leij & Ebels 2005, 2006; Birding World 18: 149, 2005, Dutch Birding 27: 221, plate 270, 223, plate 278, 234, plate 292, 2005, 28: 8, plate 10-11, 2006).
This first for the Netherlands was found on the same day as another first, the Eastern Imperial Eagle at Kamperhoek, Flevoland. The Killdeer was shown on prime time on Dutch television.
Greater Sand Plover / Woestijnplevier
Charadrius leschenaultii 1,7,1
30 April, Harlingen, Friesland, summer plumage, photographed (S Bernardus, O Tol, R Cazemier et al; Dutch Birding 27: 223, plate 277, 2005).
Most probably, this was the same bird as the one at Halmstad, Halland, Sweden, on 3-4 May, based on the presence of a single white feather in the left wing. It belonged to the subspecies group C l leschenaultii/crassirostris. A record near Battenoord, Zuid-Holland, on 16 September 2004 is still in circulation to determine the subspecies; it has already been accepted and published as Greater Sand Plover (cf van der Vliet et al 2005).
Pacific Golden Plover / Aziatische Goudplevier
Pluvialis fulva 9,22,0
After review, the CDNA has decided that an adult in summer plumage at Middelburg, Zeeland, on 13-15 September 1991 should remain accepted as Pacific Golden Plover.
Semipalmated Sandpiper / Grijze Strandloper
Calidris pusilla 0,6,1
21-26 August, Wagejot, Texel, Noord-Holland, adult, summer plumage, photographed, videoed (A Wassink, D Kok, B van den Boogaard et al; Ebels 2005a; Birding World 18: 321, 2005, Dutch Birding 27: 354, plate 429, 365, plate 445, 2005).
The first record since 1998. The bird was observed well and photographs even show the notorious webbing between the toes! Previous records were in June 1989, July 1996, July 1997 (also at Wagejot, Texel), July 1997, August 1997 and August 1998.

After the untwitchable bird in 2004, birders soon got another chance to see this species. There are now five records with previous ones in May 1987, July 1996, July 1998 and July 2004, all summer-plumaged birds.
White-rumped Sandpiper / Bonapartes Strandloper
Calidris fuscicollis 1,23,3

Buff-breasted Sandpiper / Blonde Ruiter
Tryngites subruficollis 3,25,0
2001 15 August, Makkumer Zuidwaard, Wûnseradiel, Friesland (M Versluys).

The 1982 record is chronologically only the fourth. A report at Zwarte Haan, Friesland, on 5 August has not (yet) been submitted (cf van Dongen et al 2005).
Great Snipe / Poelsnip
Gallinago media -,23,1
13 September, Hessenpoort, Zwolle, Overijssel, photographed (D C Uit de Weerd, L J Steen).
September is the best month, with eight records since 1980. Two reports have not (yet) been submitted (cf van Dongen et al 2005): at Kamperhoek, Flevoland, on 28 April, and Nolledijk, Zeeland, on 14 October.
Long-billed Dowitcher / Grote Grijze Snip
Limnodromus scolopaceus 0,19,0

Despite the time gap of three weeks, the latter two records are considered to refer to the same bird. A report near Swalmen, Limburg, on 5 May has not (yet) been submitted (cf van Dongen et al 2005).
Franklin's Gull / Franklins Meeuw
Larus pipixcan 0,6,1
13 July, Kwade Hoek, Stellendam, Goedereede, Zuid-Holland, adult, summer plumage, photographed (P Stins, P A Wolf et al; Dutch Birding 27: 355, plate 434, 2005).
2004 8 December, Zuidpier, IJmuiden, Velsen, Noord-Holland, adult, winter plumage (B van Dijk, B van Buren).
The winter record is not without precedent, as one was seen in February-March 2000. However, mid-summer records are the norm.
Kumlien’s Gull / Kumliens Meeuw
Larus glaucoides kumlieni 0,0,0
The second-winter photographed on Terschelling, Friesland, on 30 January is still in circulation (Bunskoek 2005; Dutch Birding 27: 153, plate 193-195, 2005).
Ring-billed Gull / Ringsnavelmeeuw
Larus delawarensis 0,8,0
17 September to 13 March 2006, Tiel, Gelderland, adult male, photographed (R Gerritsen et al; Dutch Birding 28: 58, plate 77, 2006).

The Groningen bird is only the second that was not in adult plumage, after a second-winter in April 1996. The Goes bird, first seen in January 1998, did not return in the winter 2005-06.
Ross's Gull / Ross' Meeuw
Rhodostethia rosea 1,13,0
2004 29 November, Camperduin, Bergen, Noord-Holland, adult, winter plumage (N F van der Ham).
This is considered to refer to the same bird as present at Scheveningen, Zuid-Holland, on 20-24 and 27 November (van der Vliet et al 2005).
Black Guillemot / Zwarte Zeekoet
Cepphus grylle 31,53,3
16 July, Nes, Ameland, Friesland, adult, summer plumage (M Bot); 20 August, Maasvlakte, Rotterdam, Zuid-Holland, adult, summer plumage (M Renders, N van Houtum); 6-15 October, Westerslag, and 18-19 October, De Koog, Texel, Noord-Holland, adult, winter plumage, photographed (P L Meininger et al).

2000 30 November, Camperduin, Bergen, Noord-Holland, adult, winter plumage (N F van der Ham, G J de Haan).
This species will no longer be considered from 1 January 2007 onwards.
Eurasian Eagle Owl / Oehoe
Bubo bubo 1,45,-
1992 1 October, Mook, Mook en Middelaar, Limburg, photographed, picked up injured and taken into care at Burgers’ Dierenpark, Arnhem, Gelderland (M van Ginneke).
This record was lost in the mail, so the CDNA is pleased that it has finally been accepted. It was chronologically only the fifth record. This species is no longer considered since 1 January 2004.
Northern Hawk Owl / Sperweruil
Surnia ulula 1,1,1
30-31 October, Hooghalen, Aa en Hunze, Drenthe, first-winter, photographed, videoed (H L Holtkamp, E J Alblas, P van Wetter et al; Alblas 2005, van Wetter et al 2006; Birding World 18: 425, 2005, 19: 31, 2006, Dutch Birding 27: 429, plate 533, 450, plate 562, 2005, 28: 292, plate 409, 293, plate 410, 294, plate 411-413, 2006).
For most birders the highlight of 2005. It showed very well on its second day (when the news broke) but surprisingly had left the area the following day. It belonged to the nominate subspecies S u ulula. Previous records were on 5 October 1920 at Amerongen, Utrecht (collected) and 2 April 1995 at Brunssum, Limburg.
* Eurasian Pygmy Owl / Dwerguil
Glaucidium passerinum 0,1,0
2002 4 October, Sumarreheide, Sumar (Suameer), Tytsjerksteradiel, Friesland, picked up and released, videoed (J Deinum; de Jong 2004ab).
The first record. Because there were no reports of notable southward movements in Scandinavia in the autumn of 2002, this bird most probably originated from the German population; the nearest breeding locations are in Nordrhein-Westfalen and Niedersachsen. It was first identified as Little Owl Athene noctua and only correctly reidentified in February 2004, when video-stills were sent to Johan de Jong.
Alpine Swift / Alpengierzwaluw
Apus melba 7,37,2
30 April, Breskens, Oostburg, Zeeland, photographed (G Troost, J Leclercq; Dutch Birding 27: 284, plate 343, 2005); 6 May, Huizer Pier, Huizen, and Stichtse Brug, Blaricum, Noord-Holland (H van Oosterhout, R Alma).
European Roller / Scharrelaar
Coracias garrulus 53,16,1
15-20 September, Ecomare, Texel, Noord-Holland, adult, photographed (L J R Boon, R van Rossum et al; Birding World 18: 372, 2005, Dutch Birding 27: 350, plate 424, 429, plate 534, 431, plate 536, 2005).
The first since 1998, reflecting an obvious decline in records. The best months are May and June with 21 and 27 records, respectively. There are now five records from September, and, coincidentally, also five from Texel, with previous records in May 1964, June 1966, May 1971 and June 1980. A report near Huijbergen, Noord-Brabant, on 29 May, has not (yet) been submitted (cf van Dongen et al 2005).
Calandra Lark / Kalanderleeuwerik
Melanocorypha calandra 0,2,1
27 May, Eemshaven-Oost, Eemshaven, Eemsmond, Groningen, photographed (R Hovinga, E Klunder, M Bot et al; Hovinga & Olthoff 2005, Hovinga 2006; Dutch Birding 27: 294, plate 360, 2005, 28: 231, plate 314, 2006).
This bird stayed for c 1.5 h. Previous records were at Castricum, Noord-Holland, on 10 October 1980 (ringed), and on Texel, Noord-Holland, on 16 May 1988.
Greater Short-toed Lark / Kortteenleeuwerik
Calandrella brachydactyla 3,29,2
21 April, Hee, Terschelling, Friesland, photographed (A Ouwerkerk; Birding World 18: 148, 2005, Dutch Birding 27: 225, plate 282, 2005); 18 November, Kennemerduinen, Bloemendaal, Noord-Holland, ringed, photographed (J Vegelin, J van Tussenbroek, P Kooij et al).
As in previous years, there were several records of fly-bys at different migration hot-spots which have not been submitted. One briefly reported at Westerplas, Schiermonnikoog, Friesland, on 25 September has not (yet) been submitted either. The Kennemerduinen bird is the latest ever; there are only two previous November records (7 November 1981 and 10 November 2000).
Olive-backed Pipit / Siberische Boompieper
Anthus hodgsoni 0,15,1
7 October, Maasvlakte, Rotterdam, Zuid-Holland, photographed, videoed (W van Rijswijk, J den Hertog, E B Ebels et al; Dutch Birding 27: 431, plate 538, 2005).
2004 3-6 October, Lange Paal, Vlieland, Friesland (F Ossendorp, H A M Prinsen, L B Steijn et al).
The 2004 bird is another individual than the one already accepted for exactly the same four days near the Badweg on the same island (cf van der Vliet et al 2005). A report on Texel, Noord-Holland, on 13 October is still in circulation (cf van Dongen et al 2005).
Red-throated Pipit / Roodkeelpieper
Anthus cervinus 25,51,-
1981 10-11 May, Rijswijkse Buitenpolder, Buren, Gelderland, maximum of two (on 11 May).
This record has previously been published with wrong municipality and province (cf van den Berg & Bosman 1999, 2001). This species is no longer considered since 1 January 1992.
Thrush Nightingale / Noordse Nachtegaal
Luscinia luscinia 7,49,3
21 May into June, Flevocentrale, Lelystad, Flevoland, at least two (second from at least 25 May), at nest, singing, photographed, sound-recorded (G J ter Haar, R Halff, F Geldermans et al; Dutch Birding 27: 286, plate 348, 2005); 22-25 May, Meyendel, Wassenaar, Zuid-Holland, singing, sound-recorded (J Noordhuizen, R van der Vliet, A Remeeus et al).
Breeding was reported at Flevocentrale but the outcome has not been submitted to the CDNA. This would represent the second breeding record; the first breeding took place in 1995 at Horsterwold, Flevoland (van Beusekom 2001).
Red-spotted Bluethroat / Roodsterblauwborst
Luscinia svecica svecica 24,40,0
2004 9 May, De Cocksdorp, Texel, Noord-Holland, male (A Wassink, P Duin); 28 May, De Cocksdorp, Texel, Noord-Holland, male (A Wassink, K Ophof).
White-throated Robin / Perzische Roodborst
Irania gutturalis 0,3,1
31 October, Roptazijl, Pietersbierum, Franekeradeel, Friesland, first-winter, ringed, found dead on 2 November, skin not retained, photographed (U Rijpma, A Bakker, S van Lingen et al; Rijpma & Bakker 2006; Dutch Birding 27: 434, plate 545, 2005, 28: 302, plate 418, 303, plate 419-420, 2006).
The fourth record and the first of the less well-known pale morph; previous records were at Maasland, Zuid-Holland, on 3-4 November 1986 (male), Wassenaar, Zuid-Holland, on 2 June 1995 (female), and Lozerheide, Limburg, on 30 August 2003 (first-year).
Ehrenberg’s Redstart / Oosterse Gekraagde Roodstaart
Phoenicurus phoenicurus samamisicus 0,0,0
A male photographed at Groote Vlak, Texel, Noord-Holland, on 10 September is still in circulation; another male on the same date at Lentevreugd, Texel, has not yet been submitted (cf Wassink & Ebels 2005; Dutch Birding 27: 366, plate 447, 2005).
Siberian Stonechat / Aziatische Roodborsttapuit
Saxicola maurus 9,22,1
26 October, Westduinpark, Den Haag, Zuid-Holland, first-winter, photographed (V van der Spek, R Berkelder, R ter Ellen et al; Dutch Birding 27: 436, plate 551, 2005).
Pied Wheatear / Bonte Tapuit
Oenanthe pleschanka 0,9,2
16 October, Paal 19, Terschelling, Friesland, first-winter female, photographed (E van Winden, A Ouwerkerk; Dutch Birding 26: 418, plate 595, 2004); 28 October to 2 November, Paal 7, Schiermonnikoog, Friesland, first-winter male, photographed, videoed (H Ruissen, E Jansen, A J van Loon et al; Dutch Birding 26: 419, plate 596-597, 2004).
Isabelline Wheatear / Izabeltapuit
Oenanthe isabellina 0,3,1
18 November, Buren, Terschelling, Friesland, first-winter, photographed (J Vink, A Ouwerkerk; Birding World 18: 454, 2006, Dutch Birding 28: 61, plate 81, 2006).
The fourth record, concerning a bird seen on the North Sea beach for c 1 h, just before dark. Previous records were at Maasvlakte, Zuid-Holland, from 21 October to 8 November 1996, at IJmuiden, Noord-Holland, on 22-23 September 2000 and on Schiermonikkoog, Friesland, on 14-25 October 2000.
Desert Wheatear / Woestijntapuit
Oenanthe deserti 1,9,9
5-10 April, Fochteloërveen, Norg, Drenthe, first-summer male, singing, photographed (W Kramer, E Schoppers, R Jansen et al; Birding World 18: 150, 2005, Dutch Birding 27: 226, plate 283, 2005); 23-29 September, Zuidpier, IJmuiden, Velsen, Noord-Holland, first-winter male, photographed, videoed (R Rotscheid, T Nagtegaal, R van Rossum et al; Birding World 18: 373, 2005, Dutch Birding 27: 432, plate 541, 2005); 29 October, Paal 2, Schiermonnikoog, Friesland, first-winter male, photographed (J Bosma et al; Dutch Birding 27: 435, plate 549, 2005); 30 October to 5 November, Wierum, Dongeradeel, Friesland, first-winter female, photographed (H van Kampen, R Cazemier et al; Dutch Birding 27: 432, plate 542, 2005); 5 November, Dashorstdijk, Almere, Flevoland, first-winter male, photographed (G Heester, D Roos, P Bertens et al); 7 November, Nes, Terschelling, Friesland, first-winter female, photographed (H Goodijk); 11-24 November, Zuidpier, IJmuiden, Velsen, Noord-Holland, first-winter male, photographed (R Rotscheid, R Altenburg, R van Dijk et al; Dutch Birding 28: 60, plate 78, 2006); 19 November, Dam 20, Vlieland, Friesland, first-winter male, photographed (C Giljam, J Reneerkens, G van Duin et al; Dutch Birding 28: 60, plate 79, 2006); 2 December, De Hon, Ameland, Friesland, male, photographed (J Huizenga, IJ de Jong).
In autumn, a remarkable influx of eight individuals took place. The birds at Zuidpier are considered two individuals because this is a well-watched site where a single long-staying bird would not have gone unnoticed for six weeks. The Fochteloërveen bird was the second in spring, after a female in April 1989.
White's Thrush / Goudlijster
Zoothera aurea 11,6,1
29 October, Hasseltsestraat, Scheveningen, Den Haag, Zuid-Holland, found dead, photographed (E Kok).
Pallas's Grasshopper Warbler / Siberische Sprinkhaanzanger
Locustella certhiola 0,5,1
20 September, Castricum, Noord-Holland, ringed, photographed, videoed (H Levering, A J van Loon, P Veldt et al; Roselaar et al 2006b; Dutch Birding 28: 276, plate 400, 2006).
The fifth record for the ringing site at Castricum; the first was on 5 October 1991. Roselaar et al (2006b) presented an overview of the five September records in 2002-05, also discussing the subspecies.
River Warbler / Krekelzanger
Locustella fluviatilis 6,36,1
1-3 July, Dordtse Biesbosch, Dordrecht, Zuid-Holland, singing, photographed (H Gebuis, T O V Muusse, P A Wolf).
Reports at Ooijpolder, Gelderland, on 15 June, and near Taarloo, Drenthe, on 26 July, have not (yet) been submitted (cf van Dongen et al 2005).
Melodious Warbler / Orpheusspotvogel
Hippolais polyglotta 2,45,-
2004 11-16 June, Sint Geertruid, Margraten, Limburg, singing, photographed.
This record was published with the wrong municipality in van der Vliet et al (2005). This species is no longer considered since 1 January 2005; de Bruin & van der Vliet (2005) erroneously stated that it was no longer considered since 1 January 2006.
Paddyfield Warbler / Veldrietzanger
Acrocephalus agricola 1,13,1
11 September, Wormer- en Jisperveld, Waterland, Noord-Holland, adult, ringed, photographed (J van der Geld, R Leurs; Dutch Birding 27: 434, plate 546, 2005).
Again a bird trapped during ringing activities. There is still only one field record, on Vlieland, Friesland, on 18 September 1994.
Blyth's Reed Warbler / Struikrietzanger
Acrocephalus dumetorum 0,7,0
2003 28-30 September, Stortemelk, Vlieland, Friesland, photographed, sound-recorded (J de Bruijn, N van Duivendijk, H Zevenhuizen et al; Dutch Birding 25: 430, plate 503, 2003).
The third for 2003, making it an even better year for this species.
Dartford Warbler / Provençaalse Grasmus
Sylvia undata 1,6,0
2004 29 December to 12 February 2005, Dwingelderveld, Westerveld, Drenthe, adult male, photographed, sound-recorded.
This record was already mentioned in van der Vliet et al (2005).
Subalpine Warbler / Baardgrasmus
Sylvia cantillans 5,43,3
10 May, Bakkum, Castricum, Noord-Holland, male, photographed (C van der Wardt, M van der Wardt, R Halff et al); 31 October to 1 November, Westerplas, Schiermonnikoog, Friesland, female (H Dufourny, V Buchet).
2004 28 May, De Uithof, Den Haag, Zuid-Holland, male, photographed, sound-recorded (W Kolber, T J C Luijendijk, F Ossendorp et al).
2003 26-27 April, Westkapelle, Veere, Zeeland, first-summer male, photographed (G van de Maat, M Renders, A Linckens et al);
2000 9 May, Rottumerplaat, Eemsmond, Groningen, female, photographed (D Lutterop, G Kasemir).
Totals include birds identified to subspecies (see below). The CDNA is still undecided on the subspecific identity of the 2004 bird: for that reason it remains in circulation. A report at Callantsoog, Noord-Holland, on 2 May, has not (yet) been submitted (cf van Dongen et al 2005).
Western Subalpine Warbler / Westelijke Baardgrasmus
Sylvia cantillans cantillans/inornata 2,4,1
7-10 July, Bleekersvallei, Texel, Noord-Holland, first-summer male, photographed (K Ophof, A Wassink, J J F J Jansen et al; Dutch Birding 27: 355, plate 436, 2005).
2003 18 May, Kollumeroord, Kollumerland en Nieuwkruisland, Friesland, first-summer male, sound-recorded (R Cazemier, M P Olthof, T Bakker et al).
* Western Orphean Warbler / Westelijke Orpheusgrasmus
Sylvia hortensis 0,1,0
2003 29 October to 5 November, Arnestein I, Middelburg, Zeeland, photographed, videoed (P A Wolf, P L Meininger, M S J Hoekstein et al; Wolf 2003; Birding World 16: 420, 2003, 17: 37, 2004, Birdwatch 12 nr 136: 63, 2003, Dutch Birding 25: 420, plate 490, 444, plate 522, 2003, 26: 71, plate 126, 2004).
A paper discussing the identification (including the separation from Eastern Orphean Warbler S crassirostris) has been prepared for Dutch Birding.
Greenish Warbler / Grauwe Fitis
Phylloscopus trochiloides 6,38,3
4-12 June, Bodegraven, Zuid-Holland, singing, photographed, sound-recorded (K Jongeneel, T J C Luijendijk, S Schilperoort et al; Dutch Birding 27: 287, plate 351, 2005); 11-12 June, ‘t Zand, Zijpe, Noord-Holland, singing, photographed, sound-recorded (R de Beer, R E Brouwer, A van de Ende et al); 31 August, De Cocksdorp, Texel, Noord-Holland (W van Rijswijk, A Wassink et al).
2004 5-9 June, Sint Laurens, Middelburg, Zeeland, singing, photographed, sound-recorded (P Beeke, C Beeke, J Walhout et al); 9 August, Groene Glop, Schiermonnikoog, Friesland, first-winter, ringed, photographed (A G Duiven, K H Oosterbeek); 3-7 October, Robbenjager, De Cocksdorp, Texel, Noord-Holland, photographed, sound-recorded (W L Janse, P van Wetter et al).
2003 29 May, Quackgors, Hellevoetsluis, Zuid-Holland, singing, sound-recorded (M Klemann).
A report from Eemshaven, Groningen, on 17-20 and 25 September, is still in circulation (cf van Dongen et al 2005). The record of October 2004 concerns a date extension (cf van der Vliet et al 2005). The record on Schiermonnikoog in early August 2004 may suggest local breeding (especially since the first breeding record was on the same island in 2003, cf Ebels 2003) but there were no other records on the island in 2004 and, therefore, it concerned most likely ‘just’ an early migrant.
Hume's Leaf Warbler / Humes Bladkoning
Phylloscopus humei 2,28,1
20 November to 14 January 2006, Oosterbeek, Renkum, Gelderland, photographed, sound-recorded (S Terlouw, M van Duijn, M P Lantsheer et al).
Radde’s Warbler / Raddes Boszanger
Phylloscopus schwarzi 2,14,1
15 October, Oost-Vlieland, Vlieland, Friesland (L B Steijn, R F J van Beusekom, N van Duivendijk et al).
Dusky Warbler / Bruine Boszanger
Phylloscopus fuscatus 1,42,1
29 October, Castricum, Noord-Holland, ringed, photographed (A Wijker et al).
2004 9 October, Ouddorp, Goedereede, Zuid-Holland, photographed, sound-recorded (M Renders, N van Houtum, G Bakker et al); 17 October, Oost-Vlieland, Vlieland, Friesland (F Ossendorp, J Scharringa, J Eerdmans et al).
The Ouddorp bird was submitted as Radde’s Warbler P schwarzi but the documentation convinced the CDNA to accept it as Dusky, again showing that the identification of these species is not always straightforward. A report from Oostkapelle, Zeeland, on 22 November has not (yet) been submitted (cf van Dongen et al 2006).
Siberian Chiffchaff / Siberische Tjiftjaf
Phylloscopus collybita tristis -,19,1
11-29 October, Westkapelle, Veere, Zeeland, photographed, sound-recorded (P Palmen, P A Wolf et al).
2003 c 15 November to 12 February 2004, Harlingen, Friesland, sound-recorded (M Versluys, M S Robb, M Brandsma et al).
Several reports are still in circulation: on Ameland, Friesland, on 19-20 November; at Lauwersmeer, Groningen, from 20 November to 4 December; Kollumerpomp, Friesland, on 26 November to 8 December; and Alkmaar, Noord-Holland, on 23-28 December. The identification of birds at Groene Glop, Schiermonnikoog, Friesland, on 2 November 1995 (trapped) and at Laakse Strand, Zeewolde, Flevoland, on 18 October 1998 have been confirmed after review. One at Schelle, Zwolle, Overijssel, on 20-27 November 1988 has been rejected after review. Two other old records are still being reviewed.

Lesser Grey Shrike / Kleine Klapekster
Lanius minor 21,17,1
5 October, Groote Vlak, Texel, Noord-Holland, adult female, photographed (K de Mooij, W L Janse, R van Viegen et al; Dutch Birding 27: 436, plate 550, 2005).

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 up to now 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).
