About These Birds
Przevalski's Partridge
A large Phasianidae partridge (~553 g) of rocky semi-arid terrain and loess gullies in the Gansu corridor and adjacent Yellow River basin, northern China. Closely related to Chukar but notably larger. Feeds on seeds, leaves, and invertebrates. Tolerates cold winters; forms winter coveys. Least Concern.
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.
