The Grey-winged Trumpeter (Psophia crepitans) is a South American forest bird named for its grey rump and back, as well as its loud trumpeting calls. The grey-winged trumpeter performs an elaborate and noisy courtship dance that involves strutting, leaping, and sometimes somersaults to impress a potential mate. These displays often take place in forest clearings where large groups of the birds gather. The dance is accompanied by loud, trumpeting calls, which contribute to the bird's name and the excitement of the display. It inhabits moist, dense, lowland tropical rainforests in the Amazon Basin and Guiana Shield of South America, preferring mature forests with a closed canopy rich in fruiting trees. It is found in regions including Venezuela, Brazil, Ecuador, northern Peru, and Guyana.
