Satin Bower Birds at Geehi in the Australian Alps.
The mature male is dark blue/black while the immature male and female are Green in colour. The males both mature and immature, build bowers out of twigs under low bushes. They collect bight objects, usually blue in order to attract mates. There is fierce competition and the mature males often raid the bowers of the younger birds, steal their treasures and destroy the bowers.
