Bambusicola sonorivox

Taiwan bamboo partridge, also known as red-footed bamboo partridge (English: Taiwan bamboo partridge, scientific name: Bambusicola sonorivox), the genus name consists of two parts, "Bambusi" is the Malay word for bamboo, and "cola" means to live, which together refers to the habit of this genus species to move in bamboo forests, which just matches its English name Bamboo-partridge. The specific epithet "sonorivox" is also composed of two parts, "so-nori" means to make noise, and "vox" means sound, which together is used to describe the frequent noises made by bamboo partridges. A medium-sized, mostly brown terrestrial bird with a slate-gray head, a dark orange throat, and rust spots on the sides and wings. Endemic to Taiwan, it inhabits lowland and foothill forests with dense understory vegetation and marginal vegetation, making it difficult to observe. It forages on the ground, usually in pairs, sometimes in small groups. The song is a continuous trill that gradually rises, reminiscent of a bathtub toy. It is gray from the face to the chest, and the throat is chestnut; the body is generally brown, with white spots on the back and gray feet. Males and females are the same color and difficult to distinguish. The body length is about 25 cm.

It lives in the woods at low and medium altitudes in Taiwan, China. It was once classified as a gray-breasted bamboo partridge. It lives in groups of three or five and often appears in the woods, pecking food. It feeds on fruits, seeds, insects and leaves. The call is similar to "chicken dog good~ chicken dog good~". At night, it rests in the trees and has poor flying ability.

The Taiwan bamboo partridge was once a subspecies of the gray-breasted bamboo partridge (Bambusi-cola thoracicus) widely distributed in the south of the Yangtze River in mainland China, but later it was promoted to a species based on morphological, genetic and singing differences. The difference between the two is that the Taiwan bamboo partridge has less chestnut area on the face, the crescent pattern on the flank is chestnut, and the waist and back are gray.

The Formosan bamboo partridge is a common species in the bamboo forests and shrubs at low altitudes of 300-1200 meters in Taiwan. It likes to move in family groups. At dawn and dusk, it is often heard making loud calls of "Ji Gou Guai, Ji Gou Guai..." This species was once a traditional hunting bird, but is now strictly protected by law. The bamboo partridge and the Gallus genus are sister genera in evolution.

Listed in the 2012 Red List of Endangered Species of the World Conservation Union (IUCN) ver 3.1 - Least Concern (LC). It has been included in the List of Terrestrial Wildlife with Important Ecological, Scientific and Social Values.
