(Ptilonorhynchidae), a family of birds of the order Passeriformes. The body of the bowerbird is 23–35 cm in length. The plumage is gray or dark brown with yellow or orange-red, or, more rarely, green or violet coloring. There are 22 species, which inhabit Australia, New Guinea, and adjacent islands. The birds live in forests and shrub thickets. The males build cones, or bowers (up to 2 m high) out of sticks around small trees and decorate them and the area in front of the entrance with bright or shiny objects, including flowers, fruits, shells, and beetles. Some bowerbirds, especially the satin bowerbird (Ptilonorhynchus violaceus), decorate the walls of the bower with the flesh of fruits or crushed coal mixed with saliva. The male sings his mating call near the bower for several weeks and even months. The pubescence of the females and mating take place at the beginning of the rainy season, when insects appear which are the food for the nestlings. The nests are built in trees or in bushes. Each clutch contains one, two, or three eggs.
