The male Venezuelan sylph (Aglaiocercus berlepschi) is a striking bird, with a dark green glittering crown, shining bronze-green underparts and a distinctive bright blue throat patch, known as a ‘gorget’. The male’s long and broad outer tail feathers are deep violet at the base, fading to blue at the ends, while the central tail feathers are shorter and blue-green in colour. It also has a short black bill (2).
The female Venezuelan sylph is also eye-catching, with green upperparts, a blue crown and throat, and a white breast and belly. The green tail feathers of the female are shorter than the male’s and are slightly forked. The Venezuelan sylph is a member of the Trochilidae, or hummingbird, family (2).
