[edit] Habitat

Prefers open and semi-open areas from sea level to high into mountains. Seen more often in the lower, drier areas. The range of habitats include ornamental gardens and other cultivated areas in addition to the original scrub-forests and higher elevation wetter forest. As many hummingbirds, they augment the diet with insects. Being somewhat flexible in diet is a must in an area where Hurricanes occur somewhat regularly.
