Green-backed robin Pachycephalopsis hattamensis

A medium-sized bird of mid-montane forest understory. Olive back, dirty yellow-green underparts, rufous wing, grey head with a black line bordering the white throat. Like other robins, likes to perch on low, diagonal branches, scanning the ground for insect prey. Similar to White-faced Robin, but Green-backed is larger with rufous wing and dingier, more greenish underparts. Voice, a falling-then-rising “peeoo-wit!” and other rasping notes.
