The male crestless bowerbird is completely drab. His plumage is indistinguishable from the female's. His bower has therefore grown more elaborate to take the place of colorful feathers. He gathers insect skeletons, shells, seeds and charcoal, and arranges them in neat piles in his bower. While bobbing about to attract the female, he holds a colorful object, usually a flower, in his bill.
