Bowerbirds and catbirds make up the family Ptilonorhynchidae. All are small to medium in size and their distribution is centered around the tropical northern part of Australia-New Guinea.

Their most notable characteristic is the extraordinarily complex behaviour of males, which build a bower to attract mates: a collection of look-alike objects that are carefully collected, sorted, and arranged by colour into spectacular structures, often including some hundreds of shells, leaves, flowers, stones or berries. This has led some researchers to regard the bowerbirds as the most advanced of any species of bird.

Though bowerbirds have traditionally been regarded as closely related to the birds of paradise, recent DNA-DNA hybridisation studies suggest that while both families are part of the great corvid radiation that took place in or near Australia-New Guinea, the bowerbirds are more distant from the birds of paradise than was once thought. Sibley's landmark DNA studies placed them close to the lyrebirds; however, anatomical evidence appears to contradict this and the true relationship remains unclear.

DNA-DNA hybridisation: DNA-DNA hybridization is a method in genetics to measure the degree of genetic similarity between DNA sequences. The technique is usually used to determine the genetic "distance" between two species. When several species are compared that way, the similarity values allow the species to be arranged ...

Australia-New Guinea: Australia-New Guinea, also called Sahul or Meganesia, is made up of the continent of Australia and the islands of New Guinea and Tasmania. These land masses are separated by the Torres Strait (Australia and New Guinea) and the Bass Strait (Australia and Tasmania). However, from biological and geolog...
