Crested Partridge

A small partridge (~250 g) of family Phasianidae, males with vivid crimson crest and iridescent green plumage. Found in lowland tropical rainforests of Southeast Asia including Thailand, Malaysia, Sumatra, and Borneo. Forages on the forest floor for fallen seeds, fruits, and invertebrates. Vulnerable; dependent on primary lowland forest, heavily impacted by deforestation and palm oil expansion.

Greater Prairie-chicken

A medium-sized grouse (~870 g) of family Phasianidae, with barred brown plumage and elongated pinnate feathers raised during lek displays. Males inflate orange air sacs and boom loudly at communal leks. Inhabits native tallgrass prairies of central North America. Feeds on grain, seeds, and insects. Near Threatened; dramatic population collapse due to tallgrass prairie conversion and fragmentation.
