About These Birds
Tan-breasted Partridge
A medium-sized partridge (~335 g) of family Phasianidae, with plain tan-brown breast and muted brown upperparts. Endemic to the Natuna Islands of Indonesia. Inhabits tropical forest. Forages on the forest floor for seeds and invertebrates. Least Concern; while restricted to small islands, remains stable; its insular endemism makes it vulnerable to future habitat clearance or introduced predators.
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.
