At 15–16 cm length—somewhat larger than a blackcap—this is one of the largest species of typical warblers. The adult males have a plain grey back. The bill is long and pointed and the legs black. The male has a dark grey head, black eye mask, and white throat. The iris is white. Females and immatures have a paler head and reddish underparts; their grey back has a brownish tinge. The iris is dark in young birds. The song is a series of warbling liroo-liroo and scolding notes. Song is more varied than the western Orphean warbler,[3] approaching Nightingale in richness.[3]

These small passerine birds[4] are found in open deciduous woodland. 4–6 eggs are laid in a nest in a bush or tree. Like most "warblers", The eastern Orphean warbler is an insectivore.
