The ornate green and white fanning cheek feathers set the male Frilled Coquette apart from most hummingbirds. It might only be confused with the Dot-eared Coquette (Lophornis magnificus) which has a more dot-like pattern on its cheek feathers. Male Frilled Coquettes boast a long, rufous crest and both sexes have a light rump band. Common throughout their range, this species is a denizen of a variety of habitats in central eastern Brazil—humid forest edges, secondary growth, coffee plantations, and cerrado. They feed on both arthropods and nectar and may exhibit seasonal movements after the breeding and flowering seasons. In interactions with larger hummingbirds, Frilled Coquettes are considered subordinate.
