The male Green Crowned Brilliant (Heliodoxa jocular) displays a jewel like green iridescence over most of his body. It has a small violet patch on his throat, and a large, deeply forked blue-black tail. This hummingbird is a very fast flyer, allowing the sun's rays to be briefly reflected as he dances through the forest. It breeds in the highlands and then migrates to the lowlands of the Caribbean slopes. It feeds on Heliconia and other large flowers and, unlike other hummingbirds, often perches to feed.
I photographed this one in the central mountains of Costa Rica, using a multiple strobe set-up, a Canon 7D and a 70-300mm lens. I would, of course, appreciate any comments, specially suggestions for improvement.
