Dulit Partridge
A poorly known Phasianidae partridge (~748 g) restricted to montane forests of central Borneo, including the Dulit Range. Very few specimens have been collected; biology largely undescribed. Forages on forest floor for seeds and invertebrates. Data Deficient due to extreme scarcity of records.
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.
