Colaespina Papú Orthonyx novaeguineae

A medium-sized, ground-dwelling bird of mossy montane forest. Brown streaked back, gray and buff wing bars, and gray face, extending down the sides of the chest. Male has a white throat and chest whereas in the female it is orange, both edged with a black line. Very skulking and hard to see. Forages by scratching the leaf-litter. Not really similar to any other ground-dwelling birds in the mountains. More often heard than see. Song is a very distinctive, descending series of clear, penetrating, whistled notes which sound slightly out of tune.
