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.
Crested Partridge
A small partridge (~250 g) of family Phasianidae, males with vivid crimson crest and iridescent green plumage. Found in lowland tropical rainforests of Southeast Asia including Thailand, Malaysia, Sumatra, and Borneo. Forages on the forest floor for fallen seeds, fruits, and invertebrates. Vulnerable; dependent on primary lowland forest, heavily impacted by deforestation and palm oil expansion.
