Sub-alpine Warbler – records

Curruca spp – Telor BrongochVagrant

Note – Western Sub-alpine warbler Curruca iberiae

Eastern Subalpine warbler Curruca cantilans

Western  Subalpine Warblers  of the nominate race cantillans breed in SW Europe and NW Africa,  Eastern Subalpine Warblers of the the race albistriata, in SE Europe and Turkey. Spring males of the two races are readily separable by the extent of and intensity of rufous on the underparts and the thickness of the sub-moustachial stripe. Females are more difficult though the intensity of colouring can be helpful; with Eastern showing paler, colder tones on both upper and underparts. The Skomer bird of spring 2013 shows features of ‘albistriata’ but beng a female may be impossible to determine for sure. Records of Subalpine Warblers in Pembrokeshire were confined to the Islands until a bird at St Davids Head in spring 2013.

Subalpine Warbler was removed from the list of species considered by BBRC in 2006 and is now on the WRP list of Welsh rarities.

A first-summer female trapped in the Well Heligoland on 16th May 2013. The warm tones of this year’s bird, coupled with a lack of white extending along the inner web of the second most outer tail feather, suggest that it is of the Western form (species). Skokholm Annual Report 2013

(A) SUBAPLINE WARBLER SP. RHYWOGAEH TELOR BRONGOCH
Males on Ramsey 16 Apr (GM) and at Martin’s Haven 23 Apr (STu). Circulating BBRC. As there were no photographs of the outer tail feathers and no DNA was collected these two, that were most likely Eastern Subalpine Warblers can only be accepted by BBRC as Subalpine Warbler sp
