The green-crowned brilliant (''Heliodoxa jacula'') is a large, robust hummingbird that is a resident breeder in the highlands from Costa Rica to western Ecuador. It is also known as the green-fronted brilliant, notably by the Handbook of the Birds of the World.〔 This hummingbird inhabits wet mountain forests including edges, gaps and tall second growth. It occurs typically between in altitude, mainly on the Caribbean slopes. The nest is a bulky cup of plant fibres and scales of tree ferns saddled on a thin downsloping branch. The female alone incubates the two white eggs.〔 The male green-crowned brilliant is long and weighs . It is mainly bronze-green with a glittering green crown, forehead, throat and breast. It has a white spot behind the eye, a small violet-blue throat patch, white thighs, and a deeply forked blue-black tail. The female is long and weighs . She differs from the male in that she has green-spotted white underparts, a white spot behind the eye and a white stripe below the eye, and a white-cornered shallowly-forked black tail. Young birds resemble the adult of the same sex, but are duller, bronze-tinged below and have buff throats. The green-crowned brilliant has a loud squeaky ''kyew'' call. This hummingbird feeds at the large inflorescences of ''Marcgravia '' vines, which the male will sometimes defend. It will also feed at ''Heliconia'' and other large flowers. Unlike many hummingbirds, the green-crowned brilliant almost always perches to feed. ==References== * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Green-crowned brilliant」の詳細全文を読む スポンサード リンク
