Dark-winged Trumpeter Psophia viridis Scientific name definitions

Almost but not quite a Brazilian endemic, the Dark-winged Trumpeter is found in southeast and south-central Amazonia, from the Rio Madeira east to around the mouth of the Amazon, and south immediately adjacent Bolivia. It requires mature lowland forest in areas far from human settlements, as historically it has been intensely hunted for its meat. It is arguably the least-studied member of the genus, with very few available data concerning diet or breeding, although there is no reason to suppose that the species’ ecology differs substantially from its congenerics. Like other trumpeters, it is lives in groups, sometimes occurring in large bands of up to 20 birds. Three subspecies are recognized (and a fourth has been proposed), each of which is confined to a major interfluvial region south of the Amazon and which differ in the color of the hindwing patch; recently, all three have been suggested to represent good phylogenetic species.
