The Purple crowned fairy hummingbird (Heliothryx barroti) has bright white underparts, a green back, and a long pointed tail which has black central and white outer feathers. The male has a purple crown and a purple spot at the end of the eyepatch, which is bordered below with a glittering green malar stripe. The female lacks the purple and glittering green colours on the head, and the immature bird has rufous fringes to its upperpart plumage and a dusky throat. It is found from Mexico through Belize and Central America down towards Ecuador.
