Bowerbirds /ËbaÊÉrbÉrd/ make up the bird family Ptilonorhynchidae. They are renowned for their unique courtship behaviour, where males build a structure and decorate it with sticks and brightly coloured objects in an attempt to attract a mate.The family has 20 species in eight genera.he Ailuroedus catbirds are monogamous, with males raising chicks with their partner, but all other bowerbirds are polygynous, with the female building the nest and raising the young alone. These latter species are commonly dimorphic, with the female being more drab in color.
A bower is not a nest. It is an attractive 'avenue', used by male bowerbirds to entice a female. When they are not feeding, the males spend much of their time perched in the bower, calling to potential mates and warning off potential rivals.egent bowerbirds are fruit eaters and live mainly in the upper levels of forest trees. They spend time on the ground only when bower-building, displaying and mating. Their range extends from the Eungella Range, inland from Mackay in Queensland, to the Illawarra escarpment near Wollongong.
