The purple-crowned fairy (Heliothryx barroti) is a species of hummingbird in the subfamily Polytminae, the mangoes. It is found from southeastern Mexico south into northern Peru. The purple-crowned fairy was originally described as Trochilus Barroti. It and the black-eared fairy (Heliothryx auritus) were treated as conspecific by some authors but are now considered to be a superspecies; they are the only members of the genus. Its scientific name commemorates Adolphe Barrot (1801–1870), a French diplomat who served in Colombia from 1831 to 1835.
The purple-crowned fairy is monotypic. The purple-crowned fairy is 9 to 13 cm (3.5 to 5.1 in) long and weighs about 5.5 g (0.19 oz). It is slender and has bright emerald green upperparts, pure white underparts, and a long pointed tail which has blue-black central and white outer feathers. It has a black patch through the eye and the bill is short, straight, and black. The male has a metallic violet forecrown; the eye patch has a metallic violet spot behind it and bright emerald green below it. The female has a green crown and the face has less black, no violet spot, and no green below the black... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Purple-crowned Fairy is recorded against all the birds logged in Pico Bonito National Park (212 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
