About These Birds
Sumatran Partridge
A medium-sized partridge (~335 g) of family Phasianidae, with brownish plumage and scaly underparts. Endemic to Sumatra, inhabiting primary and secondary highland forests at 600–2,000 m elevation. Forages on the forest floor for seeds, berries, and invertebrates. Least Concern; Sumatra's mountain forests retain substantial cover in protected areas, supporting stable partridge populations.
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.
