About These Birds
Taiwan Partridge
A medium-sized partridge (~260 g) of family Phasianidae, with reddish-orange throat, dark brown upperparts, and scaly underparts. Endemic to the montane forests of Taiwan at 500–2,800 m elevation. Forages on the forest floor for seeds, berries, and invertebrates. Least Concern; Taiwan's mountain forests are well protected, supporting stable populations of this island endemic.
