Andean Gockofthe Rogk

I his vivid bird occurs in forest by streams and in wooded gorges of the Andes, feeding on fruit. The highly colored males perform noisy, communal courtship displays, at special sites known as "Icks," on bare branches in middle and upper vegetation. During display, males extend the crest forward, completely covering the bill. The shape of the eye also changes from round to narrowly elliptical. The females arc-cinnamon brown all over and have smaller crests than the males. They visit the lek and watch the displaying males, and eventually each female selects a mate. After mating, they perform all nesting duties and parental care, unaided by the males.
