About These Birds
Ferruginous Partridge
A small partridge (~210 g) of family Phasianidae, with rich ferruginous (rust-red) plumage and spotted black-and-white markings. Inhabits lowland and foothill rainforests in Malaysia, Sumatra, and Borneo. Secretive, foraging on the forest floor for seeds and invertebrates. Near Threatened; associated with primary and tall secondary forest, declining with ongoing logging and land conversion.
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.
