Description edit
It has a long white supercilium and broad, dark brown eye-stripes.[2] Its crown, upper parts, and bill are also dark brown.[2] It has greenish-brown cheeks and its ear-coverts are mottled.[2] Its bill has a pink base that extends to the lower mandible.[2] Its legs are pale pinkish-brown.[2]
It is easily confused with the pale-legged leaf warbler.[2] One possible distinguishing feature is that its upperparts are slightly more greenish.[2] It is more easily distinguished by its lower-pitched vocalizations, but some overlap does exist in the species' pitch ranges.[2]
Breeding edit
It nests in shrubs.[3]
