Pembrokeshire Avifauna committee in MYP, Subalpine Warbler

Sylvia cantillans

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 David’s 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.
