About Sylvia hortensis (Gmelin, 1789)
This species, currently known as Sylvia hortensis (Gmelin, 1789), is the western Orphean warbler, one of the largest species of typical warblers. Adults measure 15–16 centimetres (6–6+1⁄4 inches) in length, and are somewhat larger than a blackcap. Adult males have a plain grey back, whitish underparts, a long pointed bill, and black legs. Males also have a dark grey head, a black eye mask, a white throat, and a white iris. Females and immature individuals have a paler head and buff underparts, and their grey back carries a brownish tinge. Young birds have a dark iris. The song of this species consists of a series of warbling liroo-liroo phrases mixed with scolding notes. These small passerine birds live in open deciduous woodland. They build their nests in bushes or trees, and lay a clutch of 4 to 6 eggs per brood. Like most warblers, the western Orphean warbler is insectivorous.
