Chestnut-bellied Hummingbird

The chestnut-bellied hummingbird is about 9 cm (3.5 in) long. Both sexes have a black bill with a red base to the mandible. The adult male has bronze-green upperparts and a chestnut tail. Its throat and upper breast are glittering green, the belly chestnut, and the undertail coverts chestnut with greenish edges. The female is similar but with a slightly paler belly and white bars near the end of some throat feathers. Immatures are similar to the female with rufous edges on the feathers of the neck and rump. Voice: The chestnut-bellied hummingbird's song is "a short rhythmic phrase of three squeaky notes that sounds like a rusty door-hinge, 'krey-ki-cheep ... tsew ... krey-ki-cheep ...'." It also makes calls described as " a slightly buzzy 'tzee', a high-pitched 'see' and a stuttering high-pitched chattering."
