About These Birds
Chestnut-bellied Partridge
A medium-sized partridge (~270 g) of family Phasianidae, with a rich chestnut belly and boldly patterned head. Endemic to the montane forests of Java at 800–3,000 m elevation. Inhabits primary and secondary highland forest. Forages on the forest floor for seeds, berries, and invertebrates. Least Concern; well represented in Java's mountain national parks despite the island's high human population density.
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.
