Description

The black-eared warbler measures 13 cm (5.1 in) in length. It is mostly olive-brown with a buffy belly and underparts. It has distinct black and white striping on the head and a dark cheek. Male and female three-striped warblers have similar plumages.

Their song is a rapid series of squeaky chirps.

Distribution and habitat

It is found from Costa Rica to western Panama. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest. The black-eared warbler typically forages on the ground, especially near riparian areas.
