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.
Birdâs beaks are very important. They help the bird gather food and sometimes they rip, tear, or crush food. They can act as an extra hand, such as when parrots use their beak for climbing. They are used for building nests, and in some species of birds they can even tie knots.hey are also important for preening, which is making sure all of the birdâs feathers are in their proper place. The top part of the beak is called the Upper Mandible, and the lower part is called the Lower Mandible. To learn more about beaks and how they determine what kinds of food a bird eats, keep reading!
