A Black-throated Green Warbler in Iceland

A Black-throated Green Warbler Dendroica virens, found by Yann Kolbeinsson on 27 October 2003, stayed at the Þorbjörn tree plantation, just north of Grindavík (SW-Iceland) until the following day. The bird remained very tame throughout its stay while feeding in spruce trees. It is most likely a juvenile male, due to the extensive black breast and sides and much white in the three outer rectrices. Adult female is however not completely ruled out.

Below are three record shots, and a photo of the Þorbjörn plantation (situated on the north side of Þorbjörn hill). As visible, the plantation is divided in three parts. Today's warbler stayed to the right of the photo (U-shaped area), while the Yellow Warbler Dendroica petechia found there on 10 Sept 2003 to the left of the photo, above the cars. Other birds today at Þorbjörn were one Merlin Falco columbarius, a dozen of Redwings Turdus iliacus coburni, at least five Blackcaps Sylvia atricapilla, one Willow Warbler Phylloscopus trochilus, two Goldcrests Regulus regulus, one Common Raven Corvus corax, one Brambling Fringilla montifringilla, one Common Redpoll Carduelis flammea and a fly-by Snow Bunting Plectrophenax nivalis. Four American passerines have been recorded at Þorbjörn prior to this year; a Red-eyed Vireo Vireo olivaceus on 4 Oct 1984, an Indigo Bunting Passerina cyanea on 20 Oct 1985, a Yellow-rumped Warbler D. coronata on 13 Oct 1991 and a Blackpoll Warbler D. striata on 28 Oct 2001.

This is Iceland's first-ever record of Black-throated Green Warbler! There is one B-category record of this species in the Western Palearctic; a first-winter male collected at Helgoland/Germany on 19 Oct 1858 while a record of a juvenile female found dead on a ship at Reykjavík/Iceland on 19 Sept 1984 is placed in D-category. - YK/29.10.2003
