This glittering green hummingbird is named for its distinctive coppery rump and is one of the most common hummers on Trinidad and Tobago. It is assertive around flowering shrubs and feeders, often chasing away rivals. Both sexes look similar, and they readily visit gardens in human-dominated landscapes. The rapid wingbeats produce a noticeable hum as it hovers to feed.
