James's Flamingo mating ritual

The James's Flamingo (Phoenicopterus jamesi), also known as the Puna Flamingo, is a South American flamingo, named for Harry Berkeley James. The entire colony may participate in mating rituals at the same time. The males put on a show by vocalizing and sticking their necks and heads straight up in the air and turning their heads back and forth.
