Куріпка острівна Bambusicola sonorivox

Medium-sized, mostly brownish terrestrial bird with a slate-gray head and neck, dark orange throat, and rusty spots on sides and wings. Endemic to Taiwan., where it inhabits lowland and foothill forests with undergrowth and densely vegetated edges, where difficult to see. Forages on the ground, usually in pairs, sometimes in small groups. Song is an accelerating squeaky series of notes reminiscent of a bathtub toy-- “rik-a-yeeee!”
