Technical description

Subalpine Warbler (Sylvia cantillans) is a small typical warbler which breeds in the southernmost areas of Europe and northwest Africa. This small passerine bird is migratory, and winters along the southern edge of the Sahara. Like most Sylvia species, it has distinct male and female plumages. The adult male has a grey back and head, brick-red underparts, and white malar streaks (“moustaches”). The female is mainly brown above, with a greyer head and whitish below with a pink flush. The subalpine warbler’s song is fast and rattling.
