Dark-capped yellow warbler
Superficially resembles Icterine warbler, but has darker olive-green upperparts, a yellower rump, brighter yellow underparts and dark grey legs. The two species also occupy quite different habitats. Often inconsicuous, but it sings, and may hawk insects, from an exposed perch.
Female is duller, with less contrast between the back and the underparts. Juvenile resembles female but with a buff wash.
Bracken, sedges and tangled vegetation at forest edge.
A soft 'chip-chip-cheezee-cheeze'.
