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).

The female has a green crown and the face has less black, no violet spot, and no green below the black... Wikipedia →
