About These Birds
Bornean Partridge
A medium-sized partridge (~270 g) of family Phasianidae, with rufous-orange breast and barred brown upperparts. Endemic to Borneo, inhabiting primary lowland and montane forests from sea level to 1,800 m elevation. Forages on the forest floor for seeds, berries, and invertebrates. Least Concern; broadly distributed across Borneo's forests, though logging and land conversion pose growing threats.
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.
