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.
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.
