Lance-tailed Manakin

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. It is a small, compact bird about 13 centimetres (5 in) long and similar to the blue-backed manakin, but both sexes have the two central tail feathers elongated to form a spike. Males have black plumage with a blue back, a red crown and orange legs. Females and juveniles are olive-green with paler underparts. At breeding time, males are involved in a cooperative behaviour during which they jump up and down alternately. Wikipedia →
