Psophiidae

Psophiidae is a small family of birds in the order Gruiformes, comprising a single genus, Psophia, with three extant species commonly called trumpeters: white-winged, gray-winged, and band-tailed trumpeters. They are native to tropical South America, especially the Amazon Basin, where they occupy dense lowland forests and forest edges.

These ground-dwelling birds are medium-sized with stout bodies, long legs, and brownish plumage. They often show pale patches on the wings visible in flight.

Diet consists mainly of fruit, seeds, leaves, and invertebrates, foraged on the forest floor in groups ranging from pairs to large flocks.

Their vocalizations are loud trumpeting calls used for maintaining contact within flocks and signaling territory.

Nests are built on the ground in concealed leaf litter; clutch size is small and both parents help incubate and rear the young.

Conservation: Habitat loss and hunting threaten some populations; conservation status varies by species and region.
