Overview

Overview

The Mexican Violetear inhabits montane forest edges, clearings, and gardens from Mexico south through Central America, favoring middle to upper elevations. It is a vocal and conspicuous member of many highland hummingbird communities, often heard calling from an exposed perch before it is seen.

Its body is a rich, uniform green, but patches of glittering violet-blue on the ear coverts and across the breast provide contrasting color highlights that distinguish it from other green-bodied hummingbirds in its range.

Identifying the Feather

Feather ID Notes

Most body feathers show a deep, even green iridescence, while the ear coverts carry a distinct violet-blue patch and a smaller violet patch crosses the upper breast. These violet patches can look dark without direct light but flash brightly when lit at the right angle.

  • Body feathers: rich green overall
  • Ear covert patch: violet-blue, well defined
  • Breast patch: violet-blue, narrower band across the upper chest
  • Tail: dark, slightly notched The combination of green body plus a violet ear patch and breast band distinguishes this species from the closely related Sparkling Violetear, which shows larger, more extensive violet patches.

Plumage & Molt

Plumage Details

Sexes are similar in the Mexican Violetear, both showing green body plumage with violet ear and breast patches, though patch size and intensity can vary somewhat between individuals rather than strictly by sex. Juveniles are duller, with reduced violet patches. There is no marked seasonal plumage difference, with an annual molt refreshing feather color.

Habitat & Range

Habitat & Range

This species is found in montane forest edge, clearings, second growth, and gardens at moderate to high elevations from Mexico south through Central America into parts of northern South America. Some populations show seasonal elevational movements, descending to lower elevations outside the breeding season.

Behavior & Field Notes

Behavior & Field Notes

Mexican Violetears feed on nectar from a variety of flowering trees, shrubs, and epiphytes, often defending favored flowering patches vigorously, and also take small insects. They are known for persistent, repetitive calling from prominent perches, a behavior that makes them easy to detect even when not visible. Nests are small cups built in shrubs or low trees. Calls include a sharp, repeated "tsip" note given over long periods.
