The Purus Jacamar is a heavy, chestnut jacamar of forest edge. It forms a superspecies with the similar White-eared Jacamar (Galbalcyrhynchus leucotis), which it closely resembles in all respects except cheek color. The Purus Jacamar occurs in southwestern Amazonia south of the Amazon River and east of the Ucayali River, while the White-eared is distributed to the north and west. Both species are large and stocky, with chestnut plumage, glossy blackish wings and tail, and a heavy pink bill. Like other jacamars, the Purus Jacamar forages on aerial insects by sallying from a perch. It apparently breeds in holes and may be a co-operative breeder. Birds are often seen perched in relatively open areas in groups of 4-6 individuals.
