Adult dark olive-brown with rich chestnut head and chest, greenish-yellow bill, black-and-white banded undertail, and red legs. Juvenile mostly dusky. Gives an accelerating sequence of short repeated squawks and squeaks, as well as slower clicks.

Resident species

行为

The bird's diet consists of amphibians, aquatic invertebrates, crustaceans and molluscs.<p>The bird rests on or close to ground in dense vegetation. It lays clutches of 3-5 dull-white eggs, the incubation periods of which are around 20 days. The chicks emerge covered in black down, precocial and nidifugous.<p>The crake makes repetitive clicking calls and soft grunts.

保护状况

With a large range and no evidence of significant decline, this species is assessed as being of least concern. The species is little studied and seldom seen due to its secretive nature, but appears to be locally common in New Guinea. In Australia it has suffered declines due to habitat loss.

Chlamydera cerviniventris

Medium-sized bowerbird found in a diverse range of habitats across northern Cape York and New Guinea, usually in tropical moist forest but also in shrubland, parks, and gardens. Primarily grayish brown with subtle orange wash in belly, diffuse streaking in throat and breast. Unlike in other similar bowerbirds, sexes alike. Compare larger Great Bowerbird, which has pink crest in male and lacks orange-toned underparts. Males build an impressive "U" shaped bower of sticks that they decorate with green fruit and leaves. Male song includes great variety of harsh notes and imitations of other birds.

Occurs in a variety of habitats, fairly common in suburban areas. Strong migrant, spending the middle of the year in eastern Indonesia, New Guinea and the Solomon Islands, and migrating south into eastern Australia during the austral summer. Calls are very loud, often heard at night or pre-dawn, including a piercing ‘coo-eee’, and a longer ‘wirra-wirra-wirra’ (similar to a car alarm).
