Description

It is sexually monomorphic.Donaghey, Richard Hallam, and Carolyn A. Donaghey. "Nest, egg and vocalisations of the Green-backed Robin Pachycephalopsis hattamensis in the Arfak Mountains, West Papua." ''Kukila'' 22 (2019): 21-29. It has an olive-green back, rust-colored wings, a rust-colored tail, and a yellow abdomen.Pratt, T.K. & B.M Beehler. 2015. Birds of New Guinea. 2nd edition. Princeton University Press, Princeton, New Jersey, USA.

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.
