Ruby-topaz Hummingbird

Overview

The Ruby-topaz Hummingbird is found in open woodland, savanna, scrub, and gardens across northern South America and parts of the southern Caribbean. Males are among the more dramatically two-toned hummingbirds in their range, showing distinctly different iridescent colors on the crown and throat rather than a single-colored gorget.

The chestnut-colored back and dark, somewhat squared tail provide additional contrast to the male's glittering head colors, while females are considerably plainer and can be confused with other small hummingbirds in the region.

Feather ID Notes

The male's crown feathers show a ruby-red iridescence distinctly separate from the golden-orange to topaz-colored throat feathers below, a two-toned head pattern that is a strong identifying feature. Back and body feathers are a warm chestnut, and the tail is dark and can be flared or cocked during display.

• Crown feathers: ruby-red, iridescent
• Throat feathers: golden-orange/topaz, iridescent, distinct from the crown color
• Back feathers: chestnut
• Tail feathers: dark, often cocked during display This two-toned crown-and-throat combination, paired with the chestnut back, distinguishes males from other small hummingbirds sharing their range.

Plumage Details

Adult males show the vivid crown and throat combination described above along with chestnut body feathers. Females lack the iridescent crown and throat, appearing bronze-green above and pale below with some dusky throat spotting, and often show white-tipped outer tail feathers. Juveniles resemble females, with young males gradually developing adult head coloring. Plumage is renewed by an annual molt without strong seasonal variation.

Habitat & Range

This species inhabits open woodland, scrub, savanna, and gardens across northern South America (including Venezuela, Colombia, and the Guianas) and parts of the southern Caribbean, including Trinidad and Tobago. Populations are largely resident, with some local movement tied to flowering seasons.

Behavior & Field Notes

Ruby-topaz Hummingbirds feed on nectar from a range of flowering plants in open and semi-open habitats and also take small insects. Males perform display flights and can cock their tails while perched to show off their coloring during courtship. Nests are small, well-camouflaged cups built in shrubs or low trees. Calls include sharp chip notes and buzzy chattering.
