The Crinkle-collared manucode is one of the many (and diverse) birds of paradise in Papua New Guinea. The bird occurs in mountainous regions and forests in patches in New Guinea and Misool. Males and females are similar, but the male is smaller, about 25 cm long, while the female is larger, 33 cm long. Head, neck and nape are blue-black with blue-green iridescent V-shapes on chin, throat, neck and nape. The upper part is dark blue to black. The neck and upper chest have a fluffy texture ('crinkle-collared') due to the fact that the feathers there have fringed edges. The species subsists on fruits, but supplements that with small animals and insects. During the mating lek in April to September, the male displays the fringed breast feathers while stretching his neck and head forward in time with the sound of the call. Unlike other birds of paradise, this species is monogamous. The species is not endangered but is considered to be shy and therefore difficult to see.
