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.
Red-billed Partridge
A small partridge (~225 g) of family Phasianidae, distinguished by its bright red bill on dark plumage. Endemic to montane forests of Sumatra at 700–2,000 m elevation. Inhabits the forest floor and dense undergrowth of subtropical highland forest. Forages for seeds, berries, and invertebrates. Least Concern; restricted to Sumatran mountains but currently stable with sufficient forest cover remaining.
