Rare birds in the Netherlands in 1996 Wim M Wiegant, A (Bert) de Bruin & CONA

T

hi s is the 17th annu al report on rare birds in th e Netherlands to be pub l ished in Dutch Birding. Thi s report comp ri ses records from 1996 as wei l as be lated and reconsidered records, dating from 1995 back to 1896, wh ich have been eva lu ated by the Dutch rar ities comm ittee, Commissie Dwaa lgasten Nede rl andse Avifauna (C DNA). Severa l record s for 1996 and ea rl ier years are still under consideratio n, for var ious reasons.

Deta il s included for each accepted record are, if ava il ab le: date(s); locat io n and/or municipa lity, province; number of birds if more th an o ne, plu mage and sex; type of record if trapped, photograph ed, videoed, sound-record ed o r found dead (and w here spec imen is stored); names of up to th ree observers invo lved in findin g, identifyi ng and reco rdin g, and releva nt references in th e literature, w hi ch normall y include (inter)nationa l and not reg io nal journ ais, and publ ished ph otographs. Records from 1995 lasting into 1996 wh ich were already publi shed in th e 1995 report are repeated here without references, fo r th e sake of compl eteness . Sequence of records is from 1996 backwa rds, with records w ithin one yea r presented chronologica ll y. A compil ati on of most of th e birds videoed ca n be found in Opperm an et al (1997). Numbers after eac h (sub)spec ies' name refer to the tota l number of indi vidu als 7 from 1 Janu ary 1800 to 31 December 1979, 2 since 1 Janu ary 1980 but exc lud ing 3 the current year. Sub(species) marked w ith an asteri sk * are new to th e Dutch li st.

The fo ll owi ng CDNA members voted on some or all of the records in th is report: Max Berl ijn, Ruud F J va n Beusekom, A (Be rt) de Bruin, Jan van der Laan (chairm an), Karel A Mauer, C S (Kees) Roselaa r, Jell e Sc harrin ga (secreta ry), Gerard H Stein haus and W im M W iega nt (a rc hivist). In Febru ary 1998, Gerard Ste inh aus left the committee and was succeeded by Bert de Bruin.

Records shou ld be se nt to CDNA, Postbus 45, 2080 AA Santpoort-Zuid, Netherlands, preferab ly us ing standa rd form s, w hi ch can be obtain ed free of charge from CDNA. Dec isions regarding taxonomy have been delegated to th e taxonomi c sub-committee, Comm iss ie Systematiek Nederlandse Av ifauna (CSNA), whic h co nsists of the fo llowing mem-

[Ou/eh Birding 20: 145路 167, 1998[

bers: Arnoud B van den Berg, C S (Kees) Roselaa r, Corn eli s J Hazevoet, George Sangster (sec retary) and Ronaid Sluys .

The CDNA has decided not to cons ider records of Pont ic Gu ll Larus cachinnans cachinnans (form erl y named Casp ian or Po ntic Ye ll owlegged Gull ) from 1 Janu ary 1998 onwards.

Although prior to 1997 there were very few reco rd s, if is now clear th at thi s taxon is not rare: in the w inter of 1997/98, at least 60 were reported. Also records of Ba lea ri c Shearwater Puffinus mauretanicus and Ice land Gull L glaucoides wil l no lo nger be considered fro m 1 Janu ary 1998 onwards. Of co urse, o lder record s of these spec ies are still welcomed by th e committee.

In 1996, a cumul ati ve total of at least 356 species was record ed with three spec ies new to the Dutch li st: Wh ite-throated Need leta il Sw ift Hirundapus ca udacutus, Isa belline Wheatea r Oenanthe isabellina and Myrtle Warbier Oendroica coronata. There were second record s of Lesse r Scaup Aythya a ffin is, Semipa lm ated Sandpiper Ca lidris pusilla, Red-necked Stint C ruficollis, Blyth's Pipit Anthus godlewskii and Bl yth's Reed Warbier Acrocephalus dumetorum. Other hi ghli ghts in cluded a long-stay ing male Ste ll er's Eider Polysticta stelleri and two Short-toed Eag les Circaetus ga llicus together at one site for seve ral weeks .

Systematic list of accepted records Hutchins's Canada Goose Branta hutchinsii hutchinsii 0,-,Greater Canada Goose Branta canadensis parvipes 0 ,-,22 February, A ij en, Bergen, Lim bu rg, two, photographed (J J F J Jansen, C van der Wardt, P Pa lmen); 12-13 May, Wo rku merwaard , Nijefurd, Friesland (A van der Spek); 28-29 December, Dirksland, Zu id-H o ll and, five (R-M Lafonta ine, M Peero).

1992 12 Janu ary, O udemi rdum , Caasterlan-Sleat, Friesland (R E van der V li et) .

Foll owing the CSNA dec ision to include parvipes in Greater Canada Goose Branta canadensis rather than in Lesser Canada Goose B hutchinsii, the identificat ion of sma ll G reater Canada Goose from Hutchin s's Canada Goose B h hutchinsii has been put in a di fferent li ght and has become quite difficult. Therefore, the reco rd s above, accepted as either B c parvipes or B h hutchinsii, w ill be reviewed together w ith the only prev iously accepted record, at Pi aam, N ijefurd, on 23-30 January 1994 (cf Wiegant et al 1996; Dutch Birdin g 16:

Rare birds in the Netherlands in 1996 86, p late 62, 1994, 18: 107, pl ate 104, 1996) . A prev iously accepted record on 25 janu ary 1995 at Gaast, W没n se rad iel, Fri es land, has been w ithdrawn by th e obse rver and is no longer accepted.

Th e Tersc hellin g indi vidual has also been recorded in 199 3-95 (cf Dutch Birding 19: 99, 1997) and th e two of Texel are co nsidered the same as in previou s yea rs (s ince 199 1). The tota l number is unclear due to wa ndering and returning indi vidu als. Th e reco rd of two bird s on Vlieland, Fri es land, on 8-27 May 1995, publish ed in th e 1995 report (Wiegant et al 1997) shou ld be deleted.

Th e bird was seemin gly pa ired w ith a fema le Common Shelduck Tadorna tadorna. Thi s behaviour also occurred w ith a male in th e German part of the W adden Sea in 1991. The fi rst record i n 1980-82 co ncern ed a mal e pa ired with a female Common Eider

A previou sly accepted first-winter male at Megen, Oss, Noord-Brabant, on 5-7 january 1991 (cf Dutch Birdin g 16 : 134, 1994) has been w ith drawn and is no longer accepted.

The 30 November record was the first to be documented via the In ternet, on a homepage, rather than by photograph, film or v ideo .

One wo uld co nsider an inl and location not a good pl ace for findin g rare seabirds, but there is also a reco rd of an exhausted Great Shearwater Puffinus gravis at Rotterdam , Z uid-H o ll and, approx im ately 30 km inl and.

Curi ous ly enough, th ere are no inl and records of th e mu ch co mmoner spec ies such as Sooty Shearwater P grise us. Currently, all records referring to fi eld obse rvation s are under review, since Cory's Shea rwater C borealis has now been spi it i nto Cory's Shearwater C borealis and Scopoli 's Shearwater C diomedea .

Rare birds in the Netherlands in 1996 There have been several records of more than two individuals are rather scarce. Groups of three were recorded at Lauwersmeer, Groningen, in 1987 and 1988; in Flevoland, groups of three (1973), five (1971) and eight (1984) we re reco rded. Th e 1964 record was rejected during the revision of the Dutch li st (van Ijzendoorn et al 1996). However, after exam in ation of the orig in al fi lm which emerged recently, it has aga in been accepted.

Investigations by a member of the Belgian rariti es com mittee revea led that this indi vidua l has been shot on Dutch ground. It becomes the th ird of a tota l of eight records of this highly endangered spec ies, the last dating from 1947.

* Baltie Gull Larus fuscus 0,1 ,0 1992 18 October, Schiermonnikoog, Friesland, adu lt, photographed (R 0 Winters).

The CDNA agrees w ith the conclus ions reached in the recent review of Dutch records of thi s taxon (Hoogendoorn & va n Scheepen 1998). Therefore, all previous records, w hi ch all referred to ringing recoveries, have been rejected. Thi s impli es that the above record constitutes the first of this species. A lth ough the spec ies is likely to be not as rare as its current statu s may suggest, it is bevond doubt hard to identi fy. The combination of a mantie as black as th at of Great Black-backed Gull L marinus, preferably seen in direct comparison with both G reat and Lesser Black-backed Gu ll s L graellsii, the v irtu al absence of dark head markin gs in winter plumage, a mou lt timing different from Lesser Black-backed, and a sma ll er and thinner bill all are useful identification pointers.

This series of old records by a sin gle obse rver indicates that this spec ies must be much commoner than the low numbers of accepted records suggests. A number of recently subm itted reports from Twente, Overij sse l, are st ill under cons id eration. The 1988 and 1989 records precede the on ly previously accepted

The two records from 1992 we re publi shed earlier, but now the dates have been extended. Th e 1984 reco rd refl ects a gradual change in policy of the CDNA; it is now quite co mmon for th e CDNA to accept photographi ca ll y documented reco rd s whic h have never been offic iall y su bmitted. Forme rl y, it was the policy of CDNA th at reco rd s should be submitted, if th ey were to be accepted. Th e relief of thi s policy puts documentation of records in a more important p lace th an th eir fo rm al submi ss ion. However, in cases of spec ies difficult to identi fy or of ve ry rare spec ies, CDNA may require more documentation fo r its co nsideration than a single publi shed photograph .

O nl y the second record, and the first field observati on. The first record co ncerned a bird trapped on 13 November 1983 at Westenschouwen, Zeeland.

The slow but apparently steady westerl y progress of the breeding range of this species is perhaps reflected by the fact that, for the first time, two were recorded in o ne yea r.

Thi s bird needed a real 'second look' before the observers realized th at it indeed was an Isabe lline and not a pale Northern Wheatear Ooenanthe. It stayed in the same area and in the same period as a Blyth 's Pi pit Anthus godlewskii.

Three records in one yea r, and more specifica ll y, in two days, is quite excepti onal. Contrary to Dusky Warbier P fuscatus, this spec ies still manages to elude most twitchers who are eager to see it in the field.

Stekelstaartgierzwaluw op Walcheren in mei 1996 Erik Sanders, SanderJ Lilipaly & Enno B Ebels

O

P 22 mei 1996 stonden Erik Sanders en Sander Lilipaly aan het eind van de ochtend op de stoep van het ouderlijke huis van SL aan het Seisbolwerk in Middelburg, Walcheren , Zeeland. Na een ochtendje vogelen samen met Tobi Koppejan hadden ze hier koffie gedronken; TK was net vertrokken. Om 11 :35 zag ES boven het hu is een zeer snel le en grote gierzwal uw met een witte vlek op de onderbu ik. Een minuut later vonden ES en SL de vogel laag sc herend boven het water van de buitenvest van Middelburg terug. De scherp afgesneden witte keel en het duidelijke witte hoefijzer op de onderbuik, de forse bouwen de zee r sne lle vlucht deden hen direct beseffen dat het om een Stekelstaartgierzwa luw Hirundapus caudacutus ging. Nog tweemaal v loog de voge l langs; de laatste keer, om c 11 :45, zagen z ij (samen met de telefonisch gewaarsc huwde en vervolgens in all er ijl teruggekeerde TK) de witgrijze ovaa lvormige vlek op de bovendelen. Andere vogelaars die terstond gebe ld waren kwamen te laat.

Om 15:45 zag wij len Koen Kuijpers zonder optische hulpmiddelen een Stekelstaartgierzwaluw in noordelijke richting over zich heen scheren langs de Landschuurweg bij Veere, Zee land, c 6 km ten noorden van Middelburg. KK was al de hele dag buiten aan het werk en hoorde pas van de waarneming eerder die dag toen hij TK belde om z ijn eigen waarneming door te geven!

KK zag de voge l all een van onderen; hem vielen het grote formaat en de zware bouw op, het zeer donkere uiterlijk met contrasterende witte keel en wit hoefijzer op de onderde len, de korte en recht lijkende staart en de zeer krachtige en vooral snelle vlucht. Om 15:30 had Pim Wolf in Middelburg gez ien dat groepen Gierzwaluwen Apus apus langs het Kanaal door Walcheren vlogen in de richting van Veere, om de talrijke buien die over Walcheren trokken te ontwijken.

PW besloot bij Veere te gaan zoeken . Om 15 :50 werd hij in de auto gebe ld door SL over de waarneming van KK. Bij het binnenrijden van Veere om 16:15 zag PW de Stekelstaartgierzwaluw met een groepje Gierzwaluwen rond de Onze-LieveVrouwenkerk in Veere vliegen. De vogel vloog enke le minuten rustig rond de kerk maar al snel 168

verhoogde hij zijn sne lheid en maakte duikvluchten de stad in, waarbij hij uit beeld verdween, om na en ige minuten terug te keren naar de groep Gierzwaluwen . Hierna vloog hij niet meer rustig in de groep maar op enige afstand en haa ld e regelmatig G ierzwa luwen in . Om 16:25 maakte hij opnieuw een duikvlucht, passeerde op c lam afstand en op ooghoogte en verdween vervolgens laag over de buitenvest va n Veere uit beeld. Om 17:25 werd de voge l nog eenmaal gez ien door Rob Sponselee, Richard Witte en PW; hij vloog toen op c 800 m laag boven het Veerse Bos, verdween daar naar beneden en vervolgens voorgoed uit beeld. Vele la-tallen vogelaars uit de wijde omgeving bevonden zich op dat moment op de verkeerde plek op Walcheren of kwamen 眉berhaupt te laat (cf Sanders et al 1996).

Beschrijving De beschrijving is gebaseerd op notities en schetsen van SL, ES en PW, opgesteld direct na de waarneming. Er konden geen foto's of videoopnamen gemaakt worden.

ALGEMENE INDRUK Verenkleed overwegend donker, duidelijk donkerder dan Gierzwaluw, sterk contrasterend met w itte delen.

GROOTTE & BOUW Zeer forse gierzwa luw, duidelijk groter dan Gierzwaluw, waarmee meerdere malen direct verge lijkba ar. Lichaam en kop zwaa r, achterlijf kort, dik en rond, vleugels lang en breed. Vleugelvorm minder sikkelvorm ig dan bij A lpengierzwa lu w A me/ba of Boomvalk Fa/co subbuteo. Vleugel lengte ongeveer gelijk aan lichaamslengte. Staart zeer kort en recht; tijdens wenden staart zichtbaar niet gevorkt. Snavel kort, verge lijkbaar met Gierzwa lu w. Door zwa re bouw ongeveer anderha lf keer zo grote indruk makend als Gierzwaluw.

KOP Donker bruinzwart met duidelijk afgesneden witte keel. Bovenkop egaa l donkerbruin.

BOVENDELEN Lichte w itgrijze ova le v lek op mantel en rug, breder bij nek dan bij stu it, doorlopend tot op stuit, diffuus overgaand in donkerbruin aan randen en contrasterend met verder bru i nzwarte boven delen, kop en bovenstaart. Stuit bruiner dan overige donkere bovendelen.

ONDERDELEN Borst en buik donkerbruin. Anaalstreek zeer opva llend wit, hoefijzervormig, contrasterend met donkere buik, borst en ondervleuge ls. Punten van w itte

FIGUUR 1 Stekelstaartgierzwa luw / White-throated Needleta il Sw ift Hirundapus caudacutus, Middelburg, Zee land,

22 mei 1996 (frik Sanders)

hoefij ze r doorlope nd tot aa n achterz ijde va n vleugelbasis .

V LEUGEL Boven- en ondervleugel egaa l donker bruinzwa rt. Af en toe zichtbare groenb lauwe glans op bovenvleugel.

STAART Bovenstaart donkerbruin tot bruinzwart.

NAAKTE DELEN Snavel donker. Poot en oogkleur niet vastgesteld .

V LUC HT Zeer sne l en krachtig, sneller dan G ierzwa luw. Lange gli jvluchten afgewisseld door enkele korte 'maa iende' v leugelslagen. Bij rustige v lucht (ci rkelen) vleugelslag zee r ond iep met stijf gehouden v leugels; bij duikvluchten v leugelsl agen dieper en v leugels in hoek naar achteren gehouden. Meestal v liegend op c 20 m hoogte, boven water dalend tot 1 m.

Determinatie Hoewel de vogel slechts ged urende en kele afzonderlijke ogenb likken werd gez ien leverde

de determinatie weinig prob lemen op. Het voor ee n gierzwa luw grote formaat, de zware bouw, de lange maar ook brede vleuge ls, het donker bruinzwarte verenkl eed, de grote witte hoefij zervorm ige vlek op de anaa lstreek, de contrasterende en recht afges neden w itte keel en de grij sw itte v lek op de bovendelen en de zeer snelle vluc ht pasten all een op Stekelstaartgierzwaluw (C hantIer 1993, Chantler & Driessens 1995) . De karakteristi eke witte voorhoofdsv lek werd niet vastgeste ld; door de waarnem ingsomstandi gheden en de grote vliegsnelheid van de vogel kan dit kenmerk gema kkelijk gem ist zijn door de waarnemers.

Apus-g ie rzwa lu wen konden worden uitgesloten door het versc hil in postuur met sma ll ere en meer sikke lvorm ige vleugels en de minder krachti ge vlucht. Geen van de Apus-soorten (afgez ien 169

Stekelstaartgierzwa lu w op Wa lcheren in mei 1996 van afw ijkende exemp laren met gedeeltelijk wit verenkl eed) vertoont een ovaa lvormi ge witte v lek op de bovendelen. Verwarring met de over ige drie Hirundapus-soo rten is mogelijk, hoewel geen va n deze gez ien hun verspreid in gsgebied en trekgedrag als dwaalgast in West-Europa verwacht mag wo rd en (cf Chantler & Driessens 1995). Witbuikstekelstaartgierzwaluw H cochinchinensis (oostelijk Him alayageb ied en ve rspre id in Z uidoost-Az ië, overw interend in Th ai land, Maleisië en West-Indonesië) lijkt sterk op Stekelstaartgierzwaluw, met name door de verge lijkbare I ichte vlek op de bovendelen maa r heeft een minder opva ll ende, vuilw itte keelvlek, die ge leidelijk overgaat in de donkerbruine borst. Reuzensteke lstaartg ierzwa luw H giganteus (zuidpunt van het Indisch Subcontinent, Zu idoost-Azië, Palawa n en Culi on, Filippijnen, en Grote Sundaeil anden, Indones ië) is grote r en heeft een minder opvallende I ichte vlek op de bovendelen en een vee l minder co ntraste rende li chtbruine keelv lek. Zwarte Stekelstaartgierzwaluw H celebens is (Noordoost-Sul awes i, Indones ië, en Filippijnen) is bijna gehee l glanzend zwart en mist zowe l de lic hte keelvlek als de lichte v lek op de boven delen (C hantl er 1993, Chantler & Driessens 1995).

ren ten minste 17 geva ll en bekend, waarvan de helft op de Britse Eil anden. Voor de Br itse geva llen is lastig exact te bepalen om hoevee l verschi ll ende exemp laren het de laatste 15 jaa r gaat.

Verspreiding en voorkomen Stekelstaartgierzwaluw broedt van Centraa lSiberië, via Noord-China en Zuidoost-Mongolië, Noord-Mantsjoer ije en Korea oostelijk tot Sakhalin en Hokkaido en Noord-Honshu, Japan, en overw intert hoofdzakelijk in Oost-Australië en het zuiden va n Nieuw-Guinea (H c ca udacutus).

Een aparte en ni et-trekkende ondersoo rt komt voor in het Himalayagebied (H c nudipes) (Cha ntl er & Driessens 1995). In tegenste lling tot de andere Hirundapus-soo rten is het een langeafsta ndstrekker. In samenh ang met het trekgedrag zijn er verscheidene waa rn emi nge n ve r buiten de regu li ere broed-, doortrek- en overw interin gsgeb ieden. Op het zuide lijke halfrond z ijn exemplaren vastgeste ld op de Seychellen (2), Fiji, Nieuw-Zeeland en de Macquarie-eilanden. In de VS is de soo rt vo lgens National Geographic Society (1987) ee n dwaalgast ('casua l') in het voo rj aa r. Op 2 1 mei 1974 werd een exemp laar geschoten op Shemya, A leoeten, A laska (G ibson & Kessel 1997). Volgens Chantler & Driessens (1995) is er één geva l bekend va n de Pribilofeil anden, Alaska. Roberson (1980) verm eldt twee geva llen aa n de Amerikaanse westkust; waarsch ijnlijk betreffen dit bovengenoemde waarnemingen.

De nad ruk op geva ll en in het late voorjaar en de (vroege) zo mer is opvallend . Slechts twee geva llen (6 en 12)

Stekelstaartgierzwa lu w op Walcheren in mei 1996 dateerden van het najaar. Dit patroon w ijkt sterk af van het beeld bij vrijwe l alle andere soorten uit Centraal- en Oost-Azië (voorname lijk ste ltl opers en zangvoge ls) die in Europa als dwaa lgast word en vastgeste ld : verreweg de meeste gevall en dateerden uit september-oktober (met kleinere aanta ll en in juli-augustus en november-december) en maar weinig uit het voorj aar. Opmerkelijk is dat het handvol waa rn em ingen van Siberische Gierzwa luw A pacificus in WestEuropa uit dezelfde periode (me i-juli ) stamt (cf Vinicombe & Cottrid ge 1996); deze soort heeft een met Stekelstaartgierzwaluw overl append broedgebied en een verge lijkbaar trekgedrag.

A nd erzijd s is dit voorkomen ook weer niet zo uitzonderlijk : zo worden de uit Zuidoost-Azië afkomstIge Oosterse Vorkstaartplevier C lareola maldivarum en de uit Oost-Siber ië afkomstige Dau rische Kauw Corvus dauuricus eveneens vooral in het voorj aar (me i-juni ) in Europa waargenomen (cf Vinicombe & Cottr idge 1996).

De waarneming van Middelburg en Veere is door de Commissie Dwaalgasten Nederlandse Av ifaun a (CDNA) aanvaard en betekende het eerste geva l voor Nederland (Wiegant et al 1998). Een eerde re melding op 28 mei 1989 bij Philippine, Sas va n Gent, Zeeuws-Vl aanderen, Zeeland, is onl angs in ged iend en na behandel ing door de CDNA afgewezen (Wiega nt et al 1998).

Dankzegging Wij danken Annika Forsten voor het versc haffen van inform atie over de Finse geva ll en.

Summary WHITE -TH ROATED NEEDLETAIL SWIFT AT WALCHEREN IN MAY

1996 On 22 May 1996, a Wh ite-throated Need letai l Sw ift Hirandapus caudacutus was seen during four short spe l Is between 11 :35 and 11 :45 at M iddelburg, Walcheren , Zee land, the Netherl ands. It was seen in fl ight (includ ing a low flight ju st above the water) by th ree observers. Later th at dav, at 15:45, the bird was seen independently by a sing le observer 2 km east of Veere, Wa lcheren, Zee land, c 6 km to the north of Middelburg. The bird was seen again over nearby Veere from 16:15 to 16:25 and again briefly at 17:25 by three more loca l observers, before f in all y disappearin g. No photographs cou ld be taken.

The bird was identified by its large size (co mpared w ith Com mon Sw ifts Apus apus present), dark blackish plum age (darker dan Common Swift), conspicuous clea r-cut white throat sha rply demarcated from the blackish breast, consp icuous w hite ' horse-shoe' on vent and undertail and greyish-wh ite, diffusely bordered oval patch on the upperparts. The wings we re long but broader, less sick le-shaped than in Apus swifts.

Furth ermore, the flight was extreme ly sw ift and power-

fu l. This comb in ation rules out all swifts (o r other fastf lying spec ies), includin g the th ree other Hirundapus species (w hich are, however, extremely unlikely ever to occur in Europe). The most simi lar species is Wh itevented Need letail Swift H cochinchinensis, but this spec ies has a du ll er w hite throat, less sharp ly demarcated from the blackish breast (cf Chantler 1993, Cha ntler & Driessens 1995).

This record was accepted by the Dutch rar ities com m ittee (C DNA) as the first White-throated Need letai l Swift for the Netherlands. A prev ious sing le-observer repo rt at Philippine, Zeeuws-V laanderen, Zee land, on 28 May 1989 was submitted only recently and was rejected by the CDNA. There have been 16 other European records of this eastern As ian long-d istance m igrant, mostly in spring (May-June). There is one record in Ap ril (in Finland), two in July (in England in the 19th century) and on ly two autumn (November) records (Ma lta and Spain).

Th ere are now seven records from Brita in (including records on different local ities presumed to refer to a sing le bird), three from Finland, one from Ireland, one from Malta, one from the Netherlands, two from Norway, one from Spain and one from Sweden. A ll records are summ ari zed. The strong spr in g dominance is remarkable fo r an eastern vagrant to Europe, as most tend to occur mainly in autumn. Thi s pattern of occurrence is, however, shared by a few other vagrants from the Far East, including Pacific Swift A pacificus.

Striped Crake at Livorno, Italy, in January 1997 On 4 January 1997 around 09 :00, Fernando Forz i found a smal I rail in a lorry park at Livorno harbour, Toscana, Italy (43 :3 5 N, 10:18 E) . The bird was in paar condition and could easily be captured by hand . It was taken to the local bird rehabilitation centre where it died the following day. It was stored in a deep freeze until being transferred, together with other bird carcasses, on 6 March 1997 to the laboratories of the Istituto Nazianale per la Fauna Selvatica (INFS) at Ozzano Emilia . Only then we realized that it was not a European species. With the help of Ripley's (1977) identification key to the genus Porzana, it was identified as Striped Crake P marginalis. The bird was measured , photographed and prepared as a mounted specimen for the INFS museum.

In size, shape and colour the bird recalled Spotted Crake P porzana, but it differred by its bright rufous belly and undertail, remarkably long toes, and high bill profile . Th e grey breast and neck indicated that it was a female, which was confirmed later by inspection of the gonads during the preparation of th e skin. M eas urements (in mm) and notes taken on the specimen befare it was skinned (after two months of sta rage in a sealed plastic bag at -20째C) were as follows: wing length 114 (maximum chord), p10 78, p9 65 (primaries numbered from inside), tail 50, tarsus 35.8, tarsus plus toe 86 (w ithout claw), toe 50.5, total head length 41 .5, bill from featherin g 16.2, from nostril 10.3, bill depth at feathering 9; weight 53.9 g, na fat deposit, pectoral muscles not emaciated. The remiges (especially the primaries) and rectrices were slightly worn. No tra ces of juvenile plumage were present and there was a single moulting feather onthe flank.

The colour of bare parts was as follows : iris pale orange, eyelids bright orange, bill greenish-grey with black culmen, leg and foot greenish.

Striped Crake is distributed through much of 172

th e eastern part of the southern Afrotropics and more patchily in countries along the Gulf of Guinea; th e northernmost occupied areas are in north ern Ni ge ria. It is an uncommon species within its normal ran ge and little is known about its habits and movements (cf Taylor & van Perlo 1998). Until the 19305, it was believed to be an Asian non-breeding visitor to Africa (cf Cramp & Simmans 1980). It usually occurs in temporary w etlands, where it breeds during the rain seasons and then retreats towards the Equator wh en the habitat becomes unsuitable. It is a nocturnal migrant and there are reports of birds being attracted to artificial lights and of birds colliding with glass panes . Striped Crake is unique among rails in adopting sequential polyandry as a mating system and also by the fact that adults undergo two complete moults per year. Postjuvenil e moult is completed within six months after hatching (Ripley 1977, Cramp & Simmans 1980, Urban et al 1986, del Hoyo et al 1996).

It may seem surprising that Striped Crake could occur in Europe, yet a captive origin is highly unlikely. Neverthel ess, the location, where only the tyres of parked lorri es offered shelter, suggests th at unnatural factors may have been involved . There are na environmental features throughout th e harbour area which might have attracted a migrant rail to land, while several wetlands, reedbeds and wasteland with a cover of tall grass are all found around Livorno, within only 1-5 km of the harbour. Two different hypotheses on the bird's origin thus appear equally plausible: either it was attracted at ni ght by the powerful harbour lighthouse or it arrived on an incoming ship. In bath cases, th e totally unsuitable habitat and the presence of predators (Yellow-Iegged Gull Larus michahellis, cats, rats) combined with the bird's paar condition and severe weather between 30 December 1996 and 4 January 1997 suggest that it had arrived very recently, probably not earl ier than the previous night. From information supplied by the harbour [Dutch Birding 20: 172-174, 1998[

5triped Crake at Livorno, !tal)!, in January 1997 authority about shipping movements, entirely passive transportation from tropical Africa can be excluded.

Although it cannot be established with certainty whether the lighthouse or a ship were partly responsible for the bird's presence, it seems clear that the Striped Crake had attempted to cross the Mediterranean and either succeeded in covering the entire c 700 km at the widest point (LivornoTunisia), but had failed to reach suitable habitat because of the lighthouse, or had failed earl ier because of reserve depletion and had landed on a ship.

There have been at least four (of which three in the Western Palearctic) previous records of Striped Crake indicating dispersal weil outside the normal range: in Morocco (November 1989), northern Algeria (January 1867), northern Libya (February 1970), and Aldabra (lndian Ocean; December 1904) (Cramp & Simmons 1980, Snow & Perrins 1998, Taylor & van Perlo 1998).

The Italian specimen fits weil within these dates.

It has been accepted by the Italian rarities committee and it becomes the fourth Western Palearctic and first European record. Such longdistance vagrancy is not something exclusive to

Striped Crake, as similar instances are even better known in other rails (del Hoyo et al 1996).

Allen's Gallinule Porphyrula alleni offers the best example of vagrancy from the Afrotropics to Europe and the Mediterranean and occurred twice at less than 50 km from Livorno during the 19th century (Arrigoni Degli Oddi 1929). There are more than 20 records of Allen's Gallinule in the Western Palearctic, mostly in October to February, with an obvious peak in December (Hudson 1974, Cramp & Simmons 1980). The only Western Palearctic record of Black Crake Limnocorax flavirostra, which has a similar Afrotropical distribution, is of a male collected near Funchal, Madeira, in January 1895 (Cramp & Simmons 1980). The date of the Livorno Striped Crake accords weil with this vagrancy pattern of Afrotropical rails. It is clear, however, that there is a far better chance of spotting the more conspicuous Allen's Gallinule in natural habitat than a secretive Striped Crake.

We are most grateful to Fernando Forzi for having attempted to rescue the Striped Crake and for the details which he provided. Information on shipping movements was kindly supplied by Massimo Moniga (harbour authority, Avvisatore

Trends in systematics _ _ __ _ __ Molecular study indicates sympatric breeding of Atlantic and Continental Great Cormorants in 8ritain In Europe, G reat Cormo rant Phalacrocorax carbo is represented by two subspecies: Atlantic G reat Cormorant P c ca rbo (hereafter carbol which inh ab its the coasts of Britain, France, Ice land and Norway, and Cont inenta l Great Cormorant P c sinens is (hereafter sinensis), w hi ch breeds mainly in inl and tree colon ies in con tin enta l Europe . In the early 19605, the north-western European population of sinensis was restricted to 800 pai rs in two co lon ies in the Netherlands. In subsequent decades. the population of sinensis in north-western Europe spectacu larl y in creased to more than 60 000 pairs in 1993 (va n Eerden & G regersen 1995). The increase co inc ided with a range expans ion to other European countri es.

Until the 19805, in land nesting of cormorants in Britain was sporad ic but since 198 1 the number of inland breedi ng pairs has in creased to more than 11 00 in 1995 and breeding attempts have been recorded at 35 sites (Goostrey et al 1998).

A lthough in land breeding is com mon ly assoc iated w ith sin ens is, the or igin and identity of th ese inland breeders has rema ined uncertain .

Sell ers (1993) attempted to determine the status of in land breeding corm orants at Abberto n Reservoir, Essex, England, on the basis of th ree 174

plumage c haracters, the shape of th e gul ar pouch and rin ging recoveries . Differences in morphology have been described and di scussed on several occas io ns (eg, Stokoe 1958, Cramp & Simmans 1977, A istrรถm 1985) but assessi ng plumage and stru ctura l differences in the field is not always easy and may be subject to age and seasona l va ri ation. G loss to body plumage is greeni sh in sinensis and bluish or blui sh-purple in carbo but the difference may be very difficult to determine in the field and its va lidity has been questioned (Ma ri on 1995). Bath carbo and sinensis develop w hi te head-feathers and wh ite thigh patches at the start of th e breed ing season. These feath ers are at thei r brightest and most extensive in the early phase of the breeding season and decrease in intensity as breed in g progresses (Se ll ers 1993). Th e extent of w hite feathers on the head is much greater in sinens is than in carbo but same carbo, mostly a id males, may acqui re heads as w hite as typical sinensis (Stokoe 1958, Cramp & Simmans 1977, A istrรถm 1985).

Therefore, the presence or absence of wh ite feathers is an inadequate bas is for ass igning lone birds to either carbo or sinensis. A istrรถm (1985) emphas ized a difference in the shape of the gu lar pouch; in sin ensis th e gul ar pouch extends further back beyond the gape than it does in carbo (Alstrรถm 1985, Lew in gton et al 1991).

Trends in systematics but Sellers (1993) noted that this appears to be an unusually helpful character to differentiate between the taxa.

In Sellers' study, none of th ese morphological characters unambiguously identifi ed the cormorants at Abberton Reservoir as either carbo or sinensis, with the possible exception of plumage gloss which was bluish in all except one bird (of 109 checked) and was, therefore, indicative of carbo (Se llers 1993). The vast majority of ad ults was already incubating at the time of Sellers' visits, which compromised assessments of the maximum extent of white feathers. The shape of the gular pouch was consistent with sinensis in 13 individuals, whereas 87 showed th e presumed carbo pattern . However, conditions were never suitable to determ ine the colour of the plumage gloss in the birds with the sinensis-like gu lar pattern .

Ringing recoveries in Essex and Suffolk, England, mostly concerned carbo from Engl and , Scotland and Wales, but included at least four sinensis from the Neth erlands and four from Denmark (Sell ers 1993). It is not clear whether these sinensis were local breeders or non-breeding visitors. Sellers (1993) concluded that the majority of birds breeding at Abberton Reservoir in 1989-90 was more likely to be carbo than sinensis, and therefore likely originated from within the British Isles rather than the continent.

However, he pointed out that the possibility that some sinensis were breed ing at Abberton Reservoir can not be ruled out.

Uncertainties about the validity of previously accepted morphological d ifferences led Marion (1995) to suggest that a molecular study may be the only way to resolve the identity of problematic individuals or populations. Recently, Goostrey et al (1998) have do ne just that. Their study was designed to establish: 7 the amount of variation within carbo and sinensis; 2 the level of differentiation of carbo and sinensis; and 3 the provenance of the inland tree-nesting cormorants in Britain. The team sampled no less than 541 individuals from 21 European populations . Seven of these populations rep resent sinensis from Denmark, Germany, Italy, the Neth erl ands and Sweden, 10 populations refer to carbo from England , France, Norway, Scotland and Wales and four are from inland English colonies (Abbe rton Reservoir, Essex; Littl e Paxton, Cam bridgeshire; Rutland Water, Lei cester; and Besthorpe, Nottinghamshire) .

The technique of Goostrey et al (1998) is known as microsatellite analysis. Microsatellites

176

are short repetltlve eleme nts of DNA that are arrayed in a tandem fashion. The number of copies of these repetitive elements varies amon g individuals and populations of cormorants (P iertney et al 1998) and can thus be used to address variou s questions in population biology (parker et al 1998).

The study revealed significant genetic variation in carbo en sinensis but leve ls of va riation are mu ch higher in carbo than in sinensis. The authors explained the discrepancy by differences in demographics (populations of carbo are muc h smaller th an those of sinensis and are separated by relati ve ly large distances, which promotes genetic differentiation), dispersion patterns (sinensis shows extensive migrations whereas carbo is generally non-migratory) and population growth (populations of sinensis have increased much faster than those of carbol .

Goostrey et al (1998) found a 'd istinct and robust separation' of carbo and sinensis which they confirmed by applying several statistical methods. The authors point out that this result is consistent with a historic separation between the two taxa and confirms the current designation of carbo and sinensis as distinct taxa. The level of divergence of carbo and sinensis is comparable with th at identified between Hooded Corvus cornix and Carrion Crow C corone but is also within the range of conspecific populations (Goostrey et al 1998). Goostrey et al (1998) concluded that the taxonomic status of carbo and sinensis remains ambiguous (cf Marion 1993, YĂŠsou 1993) and stressed the necess ity of additional studies. .

The most important finding, howeve r, was that the inland populations clustered with sinensis in phylogenetic analyses. The tree-nesting colonies thus most I ikely consist of a considerable continental European sinensis component, and are not simply the product of inland movement of carbo.

Statistical analysis revealed that the inland colonies are not composed solely of sinensis but that both taxa occur sympatrically. Some members of these colonies had genetic characteristics intermediate between those of carbo and sinensis, suggesting that some hybridization is occurring (Goostrey et al 1998).

Goostrey et al (1998) pointed out that their results have implications for the management of co rmorant populations. Large differences in mean body mass (2370 g in sinensis, 3100 g in carbol will most likely affect the energy requirements (eg, daily food intake) of sinensis and carbo. This means that different strategies may

Tre nds in system atics have to be appli ed to contro l overfi shin g by inl and and coastal breeding popul ati ons. Al so, if inl and popul ati o ns are a mi xture of th e two taxa, and perh aps include hybrids, it may become very diffjc ult to estim ate th e impact of cormo rants at f isheri es.

Solutions of third round 1998 Th e so lutions of mystery photographs V-VI of the third round of 1998 (Du tch Birding 20: 125, 1998) appear below.

V This swimming bird seen from behind was clearly not a give-away: eve n pinning the bird down to its family is already very difficult! The most importa nt features are the mainl y blackish upperpa rts with a large white area o n (at least) th e lower rear side of the head, white undertailcoverts, a w hite bar on the wi ngs and some irregul arl y distributed pale spots on the mantie and scapulars. This combi nation of features can not be found in any species of duck, diver or grebe but points in the direction of th e auks.

Two characters of Little Auk Alle alle seem to be present: the wh ite 'cur l' upwards at the rear of th e head -sides and the pale spots on the upperparts forming a hint of Little Auk's white scapul ar stripes. The latter effect is actuall y caused by some water drops, and, above all, the mystery bird misses the compact, neck-Iess structure typica l of Little Auk. Therefore, Common Guillemot Uria aa/ge, Br端nnich's Guillemot U /omvia and Razorbill A /ca torda seem better options. The lDutch Birding 20: 779-78], 7998J

grey ish cast to the blackish upperparts (most obvious on the hind-neck) finally suggests a Common Guillemot, as Br端nnich's and espec ialIy Razorbill have deeper black upperparts com pared with the slightly paler grey ish-bl ack upperparts of Common (a lthough Co mmons from

Thi s Commo n Gu ill emot in winter plumage was photographed at Lauwersoog, Groningen, Netherlands, on 4 Februa ry 1988 by Leo Boon.

Another photograph of the same bird appears as plate 135. It was id entifi ed correctl y by only six entra nts; incorrect answers consisted of a wi ld va ri ety of waterb ird s suc h as Harlequin Duck Histrion icus histrionicus (40%), Little Auk (17%), Br端nnich's Guillemot (14%), Razorbill (12%), Puffin Fratercula arctica (10%), Black-throated Diver Cavia artica, Great Shearwater Puffinus gravis and Red-necked Phalarope Phalaropus

lobatus.

VI This passerine w ith streaked upperparts, neck and crown is obv ious ly a lark; note, for in stanee, th e broad (and abraded) tertials of the mystery bird w hi ch are typical for larks, w hereas the tertials of pipits are much narrower. A prominent feature in the photograph is the lo ng, rather slim and pointed bill w hi ch reca ll s Dupont's Lark Chersophilus duponti. A closer look, however, ex poses several features that do not fit Dupont's.

Most im portantly, the bottom edge of the lower mandible is stra ight in the mystery b ird and not down-curved as in Dupont's. Furthermore, the crown is even ly dark-streaked, not show ing the darker latera l crown stripes of Dupont's. A lso, the scapu lars are diffusely dark-centred; in Dupont's, the scapulars have darker centres and are sharpl y fringed with pale, givi ng a sca ly appearance. Raso Lark A lauda razae, endemie to the Cape Verde Islands, is character ized by a long, deep-based bill, sti ll heav ier and not as sha rpl y pointed as that of the mystery bird . Raso also has a large ly pale grey bill and rather pa le ear-coverts (clearl y paler than th e crown), unlike the mystery bird.

The str ikin g bill-shape of the mystery bird also does not fit many oth er lark spec ies (includ ing all members of the genera Ca landre l/a and Melanocorypha), because these spec ies have shorter, thicker and less pointed bilis. Bills more sim il ar to that of th e mystery bird are found in Crested Lark Calerida cristata (less 50 in Thekla Lark C theklae), Wood Lark LuI/uia arbo rea, Sky Lark Aarvensis and O ri ental Lark A gulgula (a lso known as Small Skylark). Crested ca n be excl uded as this spec ies should show a di stin ct crest (w hich may seem absent occasionally), a darker

area on the lores, some dark malar striping and often a dark half-ring below the eye, w hich are all lack ing in th e myste ry bird; Wood ca n be exclud ed because this spec ies should show a different, mo re strikin g head-pattern w ith a longer supercilium. Therefore, the mystery bird mu st be either a Sky Lark or an Oriental Lark .

There are severa l differences between Sky Lark and Oriental Lark which should allow id entificati on of the mystery bird, but individ ual and subspec ifi c variation in both species demands that th ese c haracters are to be used with ca re. A genera ll y reliable and rather well-known character is the difference in primary-projection. In O ri enta l, the primaries usuall y project on ly slightly beyond th e terti als, w hil e the primaryprojection of Sky is obviously longer. This feature needs to be hand led w ith some cauti on, because when the tertials are wom or in moult the primaryprojection can be longer than wh en fre sh. The mystery bird shows a substanti al primary-projection (v isible in th e photograph on th e right w in g), w hi ch might indi cate a Sky. Note, however, that the tertia ls are heav il y worn and th at the primary-proj ect ion w ill be partly caused by this. Most pub li shed photos of Oriental show birds in late autumn (when most Western Palearctic records occ urred) and, consequentl y, show birds in fresh plumage (both Sky and O ri ental und ergo a complete summer moult). These birds typically show very short primary-projections . Th e heav il y worn tertials of the mystery bi rd, however, indi cate that the photograph was taken in spring or ea rl y summer. Oriental in this time of yea r ca n show a somewhat longer primary-projection th an autumn

birds, and can resembi e the mystery bird in primary-projection. In fact, the primary-projection of the mystery bird looks toa short for most Sky. In Sky, espec iall y w h en wo rn , the length of the primary-projection is usuall y langer th an th e di sta nce between the longest and the second longest visibl e terti al, w hereas this is of about th e sa me length in the mystery bird. Furthermore, Sky shows two o r three widely spaced primary-tips beyond the terti als ; in the mystery bird, th ere are na widely spaced primari es visibl e between the wing-tip and th e longest terti al, thu s indi cating Oriental.

Another feature for distinguishing Sky Lark and Oriental Lark is th e co lour of th e fringes of the primari es and seconda ri es. In Oriental, th e primari es and second ar ies are typ ica ll y ru styfringed, forming a rather wa rm panel on the closed w ing, w hereas in Sky the co lour of these fringes is co lder. The mystery bird does not seem to show any prominent rusty on the frin ges of th e primaries and secondaries, but thi s is difficult to judge from the photograph as these feathers can not be seen we il. There is a 51 ightl y warmer ti nge visib le o n the fringes of same primaries, but this can be present in bath Sky and Oriental.

Other differences between Sky Lark and Orienta l Lark can be found in th e head-pattern, espec iall y the loral pattem. The lores of the mystery bird are entirely pale. Thi s is typical for Oriental w hi c h shows a wide pale sa ndy-col oured lo ral area, normally w ith out the dark lo ral spot of most Sky. The fairly braad (especia ll y just behind the eye) and lo ng superc ilium of the mystery bird is aften shown by Oriental, but less fre-

Masters of Mystery quently by Sky. Th e exact bill-shape of the mystery bird also suggests O ri enta l, as the bill of Sky is no rm all y sli ghtly less long and less pointed than th at of O ri enta l.

This Oriental Lark was photographed at Eilat, Israe l, on 2 April 1993 by Leo Boo n. Plate 137 shows anoth er photograph of the sa me bird. It is interesting to compare thi s bird w ith the Sky Lark in plate 138, since both bird s were photographed in April and, consequently, both bi rds show heav il y worn tertials. Note that th e pr im ary-proj ecti on of th e Sky is mu ch lo nger than that of the Orienta l. Note also the w idely spaced pr imarytips, dark spot on the lores and relatively short and stubby billof the Sky. Plate 136 shows two not yet mentioned characters of O ri ental : the w hiti sh chin and throat w hi ch lack the dark spottin g of many Sky and the very thin, pencil-like streaks on the breast (Sky has on ave rage thicker breast-streaking on a more buffish ground co lour). The rusty fringes of th e primaries and seco ndari es are also better visibl e in this plate than in th e mystery photograph. Two further characters of Oriental not shown in either photograph of this bird are the unstreaked flanks and the pale sa nd y outer tail-feathers; in Sky there are usuall y so me dark streaks present on the flanks and th e o uter tail-feath ers are pure white (see plate 138).

This mystery bird proved extremely diffjcult to identify and only five entrants managed to id entify it correctly. Q uite surpri sin gly, most incorrect

answers were not for Sky Lark (onl y 9%) but for Dupont's Lark (56%); other in co rrect answers included Crested Lark (18%), Raso Lark (8%) and Richard's Pipit Anthus richardi (7%).

Th is ro und was even more difficult than the previous one: no one succeeded in identifying both mystery birds correctly, 11 entrants identified one bird correctl y, while all others identif ied both birds in correctly. The 11 entrants w ho identif ied either the Common Gu ill emot or th e Oriental Lark correctly are Th eo Bakker, Sietze Bernardus, Max Berlijn, Arjan Boeie, Hannu J채nnes, Harri Kontkanen, Jan van der Laan, Timo Marijnissen, Rients Niks, Gert Ottens and Dave van der Spoe l.

Na de exc ursie kon de vogel nog tot c 18:30 van flinke afstand worden gezien vanaf het fietspad langs de Grebbeberg. Om 19:00 werd een nieuw bezoek aan het terrein toegestaan maar tot grote sp ij t van de vele be lan gste llenden was de voge l onvindbaar, dit keer definitief.

157 Steltstrandloper / Stilt Sandpiper Micropa/ama himantopus, adult, Blauwe Kamer, Utrecht, 24 juli 1998 (Arnoud B van den Berg)

Twee Siberische Strandlopers in Ezumakeeg Na de acht uur voor de baas in Leeuwarden vo ltoo id te hebben besloot ik op donderdag 6 augustus de dag af te sluiten in de Ezumakeeg, aan de westkant van het Lauwersmeergebied nabij Ezumazijl , Friesland. Dit begin dit jaar ingerichte natuurgebied heeft in haar prille bestaan al het nodige aan ze ld zame voge ls opge leverd. Zo zijn er al een Amerikaanse Sm ient Mareca americana, ee n Bronskopeend M fa/cata, v ier Steltkluten Himantopus himantopus, twee Gestreepte Strand lopers Ca /idris me/anotos, een Grote Grijze Snip Limnodromus sc%paceus, vijf Poelruiters Tringa stagnatilis en drie Witwangsterns Ch /idonias hybridus waargenomen.

De eerste indruk gaf het al en ige tijd vertrouwde beeld van enkele Krombekstrandlopers C ferruginea en grote aanta ll en Kemphanen Phi/omachus pugnax. Bij het afzoeken van steltlopers in een drassig stuk in het zu idelijke deel van de Ezumakeeg viel rond 18:45 mijn oog op een vrij forse, getekende Ca lidris, die mij in eerste in stantie deed denken aan een Gestreepte Strandloper. Bijna in de seconde dat me opv iel dat de borst van de vogel we l erg intensief gev lekt was en niet gestreept en dat de voge l een roestbruin petje had, v loog de voge l met all e steltlopers op vanwege een Bruine Kiekendief Circus aeruginosus, mij ac hter latend in het dagende besef dat ik zojui st naar een Siberische strand loper C acuminata had staan te kijken. Toen de ee rste ad rena lin e was weggeëbd en een ze nu wac hti ge blik over de weer in geva llen ste ltl ope rs niets opleverde besloot ik (zak)te lefonisch hulp te zoeken. Na enke le pogingen vo nd ik Sybrand de Bruin bereid zijn avondeten te laten staan en naar de Ezumakeeg te komen.

Dit hi elp in ieder geva l mijn hartslag beneden de 180 te krijgen en ik besloot weer intensiever te gaan zoeken. Na c lO slopende minuten kwam de voge l mijn telescoopbee ld binnenlopen.:.in gezelsc hap van nóg een 'gestreepte' strandloper! Dit was hét moment o m eventjes gek te worden. Het waren toch niet twee Gestreepte Strandlopers, of waren het twee Siberi sche?

De tweede voge l léék mij een Gestreepte Strandloper vanwege het iets grotere formaat, het blekere voorkomen en de, naar het leek, du id elijk begrensde borstband. Deze voge l v iel daarom b innen 5 sec al af (oei, oei ... ). De andere voge l was intensief gevlekt, met een vrij korte, li cht gebogen snave l, een roestbruin petje en opva ll ende chevrons op de flanken. Kortom: piepen!

Mijn morele plicht om twee meer recreatieve vogelaars verderop ook op de soo rt te w ij zen zo rgde ervoor dat een nadere blik op de tweede vogel er bij in schoot.

Op het moment dat ik beide vogels eindelijk in hun te lescoop had vlogen ze all ebe i op en verdwenen achter het hogere gras. Na enke le minuten zoeken ontwaarde ik de door mij gedetermin ee rde Siberische Strandloper weer op de oude plek en kon het twitchfeest beginnen. Dit duurde ongeveer v ij f kwartier waarna de voge l, ditmaa l opgejaagd door een Blauwe Kiekendief C cyaneus, uit het zic ht verdween. De tweede 'gestreepte ' strand loper werd d ie avond niet meer waarge nom en.

De volgende dag werd de Siberische Strand loper al

DB Actueel wee r v roeg ontdekt, tot vreugde va n de ve le voge laars va n bui ten de noo rdelijke regio. Aa n het einde va n de mi ddag bes loten onder andere Ferdy Hieselaa r en Roy Slateru s naar een gemelde Poe lrui ter te gaa n zoe ken in het zu idelij ke deel va n de Ezumakeeg. Bij het afzoeken va n de slikke n ontwaa rde FH een strand loper die hij in eerste in stantie als Gestreepte Stran dl oper determin eerde. Toen RS de voge l zag rea li seerd e hij zich dat d it een Siberi sc he Strandl ope r was . Direct probee rden ze de aa ndacht va n voge laa rs c 200 m ve rd erop te trekken die de andere kant op keken . In eerste in stantie reageerde niemand ; ze hadden het te druk met het kijken naa r dĂŠ Siberi sc he Strandloper. Na en kele keren ' hij zit hier hoo r!' over en wee r geroepen te hebben drong het tot iedereen doo r dat er twee exempl aren zaten! D it tweede exempl aar zo rgde eni ge tijd voo r verwa rrin g en d isc uss ie. Hoewe l het postuur, de bruin rode kruin en oorstreek en de gev lekte onderstaartdekve ren uiteindelij k ove rdui de lij k op Siberi sc he Strandloper wezen, wa ren de chevrons op de buik en flanken moe ilij k te zien. Hi erdoor I,eek de voge l een vrij sc herp begrensde borstband te hebben. In co mbin ati e met de opva ll ende we nkbrauwstreep en de dunne lichte V op de mantel maa kte dit ve rwa rrin g met Gestreepte Strandl oper goed moge lij k. Beide voge ls b leven die avond honkvast en en we rd en bijn a tot donker door c 35 vogelaars waa rgenomen, steeds c 200 muit elkaa r.

De tweede voge l werd de vo lgende dag rond 06:30 kortstondi g waa rgenomen door M ax Berlijn. D e rest va n de dag we rd echte r tevergeefs gezocht naa r beide vogels. Wel werd als troost een adulte G rijze

Strandl ope r C p usil/a op naam gebracht door diezelfde MB. De verrass in g was dan oo k groot toe n op zo ndagoc htend 9 augustu s het eerste exempl aa r wee r opdook en z ich de rest va n de wee k o nregelmati g maa r so ms erg fraa i liet bek ij ke n. De laatste waa rn emin g dateert va n 23 augustu s; in deze peri ode is de voge l door c 200 voge laars bezocht, waaro nder Belgen, Dui tsers en Franse n. H et tweede exemp laa r we rd niet meer waa rgenomen.

Deze ontdekking betekende de tweede en derde Sibe ri sc he Stra ndl oper voo r Nederl and. De eerste bevond z ich va n 14 tot 21 september 1989 te Philippine, Zee land (Du tc h Birdin g 13 : 125 -1 27, 199 1).

Dutch Birding is a bimonthly journal w ith issues in February, Apr il , jun e, August, October and December. It publi shes original papers and notes on morphology, systematics, occurrence and di stribution ol birds in the Benelux, Europe and elsewhere in the Palearctic region. It also publishes contribution s on b irds in the Asian-Pacilic region and other regions.

The sequence ol birds in Dutch Birding basically lollows a classic 'Wetmore sequence'.

Within this Iramework, the lollowing li sts are used lor taxonomy and nomenclature: Lijst 98 Nederlandse vogelsoorten by A B van den Berg & C A WBosman (1998, Santpoort-Zuid) (taxonomy and sc ientilic and Dutch names ol birds recorded in the Netherlands); List of birds of the Western Palearctic by British Birds (1997, Blunham) (E ngli sh names ol Western Palearctic birds); the list compiled by C 5 Roselaar in Geïllustreerde encyclopedie van de vogels by C M Perrins (1991 , Weertlh w ith modilications and additions by A J va n Loon in Vogels van de wereld - complete c ecklist by M Walters (1997, Baarn) (Dutch names ol remaining birds ol the world); and 8irds of the world door C G Sibley (1996, Version 2.0, Cincinnati) (taxonomy and sc ientilic and English names ol remaining birds ol the world).

Deviations lrom and additions to these lists are based on CSNA decisions (cf Dutch Birding 19: 21-28, 1997;20:22-32, 1998).

A sc hedule ol payment rates lor authors, photographers and arti sts is available Irom the ed itors.
