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.
Lesser Prairie-chicken
A medium-sized grouse (~725 g) of family Phasianidae, paler than Greater Prairie-chicken with crimson-orange air sacs in males. Inhabits arid mixed-grass and shinnery oak prairies in the southern Great Plains of the United States. Feeds on plant matter and invertebrates. Vulnerable; severe population declines due to oil and gas development, overgrazing, drought, and loss of native shrub prairie.
