Ruby-topaz Hummingbird Identification Guide

Key Field Marks

• Small, compact hummingbird with a short, straight black bill.
• Breeding male: unmistakable — a glittering ruby-red crown paired with an incandescent golden-orange to topaz throat, chestnut-colored body, and a blackish, slightly notched tail.
• Female and nonbreeding/eclipse male: bronzy-green above, pale grayish-white below, lacking the male's iridescent head and throat colors; some show a dark central tail band with white-tipped outer feathers.
• Overall shape is stocky and short-tailed compared to many other hummingbirds in its range.

Separating It From Similar Species

• No other hummingbird in its range combines a red crown with an orange/gold throat, so adult males are essentially unmistakable when seen well.
• Females and immatures are harder to place and can resemble female Black-throated Mango or other female Amazilia-type hummingbirds; focus on the plain grayish underparts and the dark-and-white tail pattern rather than throat color.
• Told from Black-throated Mango (a similar-sized species sharing part of its range) by lacking that species' bronzy-green mango-colored body and by the tail pattern.

Where and When to Look

• Resident across northern South America (Venezuela, the Guianas, northern Brazil, Colombia) and on Trinidad and Tobago.
• Found in open and semi-open habitats: savanna, scrubby edges, gardens, and cultivated land rather than deep forest interior.
• Present year-round within its range; no long-distance migration, though some local seasonal movements track flowering.

Voice and Behavior

• Calls are sharp, dry chips and buzzy chatters.
• Males give buzzy, mechanical-sounding trills during display flights and while defending flowering shrubs.
• Feeds low in open scrub and gardens, often perching conspicuously between bouts of nectar feeding, unlike many forest hummingbirds that stay hidden.
