General

Mexican Violetear: Medium-sized hummingbird, mostly dark metallic green (appearing black in low light) with blue-violet cheek and breast patches. Wings have black primaries. Squared tail is blue-green with black band. Slightly decurved bill is black. Sexes are similar. Formerly called the Green Violetear, it has had its name changed to Mexican Violetear and has also been split by the American Ornithologist Union in 2016 into the Mexican Violetear and Lesser Violetear (out of North American range).

Range and Habitat

Mexican Violetear: Can be found in mountain forests, forest clearings, and forest edges; common from central Mexico southward into northern South America. Vagrants may show up almost anywhere, with numerous records from the southern, central, and eastern regions of the U.S., and as far north as Alberta and Ontario.

Breeding and Nesting

Mexican Violetear: Two white eggs are laid in a nest made of down, dry grass blades, and mosses bound with cobwebs and decorated with moss and lichens. Nest is built by the female and built on drooping twig or rootlet at a forest edge, stream bank, or an overhanging road bank. Incubation ranges from 14 to 18 days and is carried out by the female.

Foraging and Feeding

Mexican Violetear: Feeds high to low in vegetation on nectar and insects.

Vocalization

Mexican Violetear: Call is a repeated, sharp, loud "tsip-tsip." Also gives a jerky, dry rattle "t'iiiiissk, t'iiiiissk, t'iiiiissk." Song is an irregular, rhythmic, metallic, dry "chitik-chitik, chitik-chitik."
