The lance-tailed manakin (''Chiroxiphia lanceolata'') is a small passerine bird which breeds in tropical Central and South America from Costa Rica to northern Venezuela. This manakin is a fairly common bird of dry and moist deciduous forests, but not rainforest. The female builds a cup nest in a tree; two brown-mottled cream eggs are laid, and incubated entirely by the female for about 20 days. Like other manakins, the lance-tailed manakin is a compact, brightly coloured forest bird, typically 13.5 cm long and weighing 17.5 g. Both sexes have the two central tail feathers elongated to form a spike. The male is mainly black, with a red crown patch, bright sky-blue back, and bright orange legs. The female has olive-green upperparts, and somewhat paler olive underparts. Young males are olive, but show a red cap and the start of a blue back as they mature. This species is similar to blue-backed manakin, ''Chiroxiphia pareola'', which breeds further south and east, but the latter lacks the spiky tail, and the male has a somewhat darker blue back. The male lance-tailed manakin has an interesting breeding display, unusual in that it is cooperative rather than competitive. Two males perch next to each other on a bare stick and jump up and down alternately, sometimes giving short flights. Groups of birds may perform together, with a different stick for each pair of displaying males. Lance-tailed manakin has a number of calls, including a ''Toe-LEE-do'', a ''curry-ho'', and a frog-like buzzing croak given by displaying males. These manakins eat fruit and some insects. ==References== * ''Birds of Venezuela'' by Hilty, ISBN 0-7136-6418-5 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「Lance-tailed manakin」の詳細全文を読む スポンサード リンク
