Taxonomy
Description
The Taiwan partridge is about 28 cm (11 in) long. The male weighs about 311 g (11.0 oz), and the female weighs about 212 g (7.5 oz).[2] The crown is grey. The head has black sides, and a white eyebrow, chin and patch below the eye. The throat is white, and there is a black half collar.[8] The upperparts are olive-grey with black bars, and there are three grey bars on the rounded, rufous wings. The tail is short and rounded. The underparts are blue-grey, with white streaks on the flanks. The eye is black, with a narrow red ring around it. The beak is blue-grey, and the feet are orange-red. The female bird is similar to the male, but it has fewer streaks on its throat and more streaks on its flanks.[2]

Behaviour
The Taiwan partridge's voice is a rising and falling series of gurru calls. Duets and choruses are often heard. Single calls are similar to those of the black-necklaced scimitar babbler.[2] It forages in groups of two or three birds, eating earthworms, berries, seeds, seedlings and insects. It breeds from March to August, depending on the elevation, and it nests in a crevice or under a tree. There are six to eight white eggs in a clutch, incubated for about 24 days.[4]
Status
The species's population size is estimated to be much more than 10,000 mature birds. It is probably declining outside of protected areas, as a result of deforestation. The IUCN downlisted it to a least-concern species in 2014 because its population and range are larger than earlier estimates. It occurs in several national parks and nature reserves.[1]
