Green-backed robin

The green-backed robin (Pachycephalopsis hattamensis) is a species of bird in the family Petroicidae. It is found in New Guinea. Its natural habitats are subtropical or tropical moist lowland forest and subtropical or tropical moist montane forest.

Description
It is sexually monomorphic. It has an olive-green back, rust-colored wings, a rust-colored tail, and a yellow abdomen.

Vocalization
Both sexes vocalize. Their most common vocalization has been described as a "tu-wee" sound. They also produce "piping whistles" and "raspy chur-chatters."

Breeding and Nesting
It breeds during New Guinea's wet season, and lays eggs in cup-shaped nests low to the ground in trees. Little research has been done on clutch size, but one egg is recorded as a seemingly typical clutch size.
