About These Birds
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.
Sabah Partridge
A little-studied Phasianidae partridge endemic to forests of Sabah and adjacent northeastern Borneo. Formerly lumped with the Chestnut-necklaced Partridge; recently elevated to full species status. Biology poorly known; presumed to forage on seeds and invertebrates in lowland forest. Near Threatened.
