These pale hummingbirds inhabit arid desert scrub, thorny woodlands, dry forests, and mangroves. Their underparts are peach, turning into white on the lower belly. Birds are usually seen by themselves foraging or perching at fairly low levels. Buffy Hummingbirds are often aggressive and defend flower patches where they feed on nectar from plants like Agave and Hibiscus. They also east the juice and flesh of Armatocereus cactus fruit and frequently hawk for insects. During courtship displays, males dive down from above, creating an arc and vocalizing. These birds are considered short-distance migrants.
