Eastern Orphean Warbler
Curruca crassirostris
东歌林莺
Description
This is one of the largest species of typical warblers, measuring 15-16 cm in length—somewhat larger than a blackcap. The adult males have a plain grey back with a dark grey head and distinctive black eye mask. The white throat provides a stark contrast to the dark head. The long, pointed bill and legs are black, while the iris is conspicuously white. Females and immatures are more subdued in appearance, with a paler head and reddish underparts. Their grey back shows a brownish tinge, and young birds have a dark iris rather than the white iris of adults. The plumage is relatively plain overall, making visual identification challenging.
Identification
This species is notoriously difficult to distinguish visually from the Western Orphean Warbler. The white iris in adult males is a key distinguishing feature, as is the black eye mask contrasting with the dark grey head and white throat. Males are more distinctive than females and immatures, which have paler heads and the characteristic reddish underparts. The larger size compared to other warblers, such as the blackcap, can be helpful in the field, though size can be difficult to judge in the field.
Distribution & Habitat
This migratory species breeds around the Mediterranean, extending through the Balkans, Turkey, the Caucasus, and surrounding regions east to Central Asia. It winters in sub-Saharan Africa. During the breeding season, it inhabits open deciduous woodland, where it can be found in bushes and trees within these habitats.
Behavior & Ecology
The song is a distinctive series of warbling phrases, characterized by repeated liroo-liroo notes accompanied by scolding notes. The song is notably more varied than that of the Western Orphean Warbler, with some considering its richness comparable to that of the Nightingale. The species breeds in open deciduous woodland, building a nest in a bush or tree where 4-6 eggs are laid. The article notes it as a nectarivore.
