About These Birds
Biak Scrubfowl
インドネシアのゲルビンク湾の島々に生息するゲルビンクツカツクリ。体長30〜35cm。塚を使って産卵する習性を持つ。生息地が限定的で、森林伐採や卵の採取により絶滅危惧状態にある。
Yellow-legged Brushturkey
A medium-large megapode (~1.3 kg) of family Megapodiidae, identifiable by yellow legs and a dark bill. Inhabits lowland rainforests of southern New Guinea. Like other brushturkeys, it is a mound-builder that uses decomposing vegetation to incubate eggs. Feeds on fruits and invertebrates on the forest floor. Least Concern; relatively poorly studied species.
