|White-vented Violet-ear (Colibri serrirostris)
(aka Singing Hummingbird)
The White-vented Violet-ear is a common hummingbird in its range and habitat. Its range is from Central Brazil and Bahia to northern Argentina, central Paraguay and Bolivia. Its habitat is semi-open scrub and savanna.
|It has a long, slightly decurved bill with a violet-blue region behind the eye which often looks like a collar. Underparts are yellow-green with a blue shimmer while the undertail coverts or vent is white.
The White-vented Violetear is territorial and aggressively defends the flowers on which it feeds. Its alternative name of "Singing Hummingbird" comes from the fact that it sings all day when perched.
|Its scientific name derives from the Spanish for hummingbird - "Colibri" and "serri" meaning saw with "rostris" meaning bill alluding to the fact that its upper mandible has minute serrations on it.|
