Bowerbirds (IPA: /ˈbaʊərˌbɜrd/) and catbirds make up the family Ptilonorhynchidae. All are small to medium in size. Although their distribution is centered around the tropical northern part of Australia-New Guinea, some species extend into the central Australian desert and the cold mountainous regions of southeast Australia.

Note that the Gray Catbird (Dumetella carolinensis) and Black Catbird (Melanoptila glabrirostris) from the Americas and the Abyssinian Catbird (Parophasma galinieri) from Africa are unrelated birds that belong to different families.

The most notable characteristic of bowerbirds is the extraordinarily complex behaviour of males, which is to build a bower to attract mates. The Satin Bowerbird, Ptilonorhynchus violaceus is a Bowerbird common in rainforest and tall wet Sclerophyll forest in eastern Australia Depending on the species, the bower ranges from a circle of cleared earth with a small pile of twigs in the center to a complex and highly decorated structure of sticks and leaves — usually shaped like a walkway, a small hut or a maypole — into and around which the male places a variety of objects he has collected. These objects — usually strikingly blue in hue — may include hundreds of shells, leaves, flowers, feathers, stones, berries, and even discarded plastic items or pieces of glass. The bird spends hours carefully sorting and arranging his collection, with each object in a specific place; if an object is moved while the bowerbird is away he will put it back in its place. No two bowers are the same, and the collection of objects reflects the personal taste of each bird and its ability to procure unusual and rare items (going as far as stealing them from neighboring bowers). At mating time, the female will go from bower to bower, watching as the male owner conducts an often elaborate mating ritual and inspecting the quality of the bower. Many females end up selecting the same male, and many underperforming males are left without mates.

In a striking example of what is known as the "transfer effect," bowerbird species that build the most elaborate bowers are dull in color and show little variation between male and female, whereas in bowerbird species with less elaborate bowers the males have bright plumage. Presumably, evolution has "transferred" the reproductive benefits of bright male plumage (common among polygamous birds) to elaborate bowers, allowing males to display their fitness by means other than physical characteristics that would appear to attract predation.

This complex mating behaviour, with highly valued types and colors decorations that in many species vary in attractiveness from year to year like fashion trends, has led some researchers to regard the bowerbirds as the most advanced of any species of bird. It also provides some of the most compelling evidence that the extended phenotype of a species can play a role in sexual selection and indeed act as a powerful mechanism to shape its evolution, as seems to be the case for humans. The Extended Phenotype (subtitled "The Gene as the Unit of Selection" and later "The Long Reach of the Gene" is a 1982 book by Richard Sexual selection is the Theory proposed by Charles Darwin that states that certain evolutionary traits can be explained by Intraspecific competition eVolution is the third Album by eLDee, it was due to be released in 2008 Human beings, humans or man (Origin 1590–1600 L homō man OL hemō the earthly one (see Humus

In addition, many species of bowerbird are superb vocal mimics. Macgregor's bowerbird, for example, has been observed imitating pigs, waterfalls, and human chatter.

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. The birds of paradise are members of the family Paradisaeidae of the order Passeriformes. DNA-DNA hybridization generally refers to a Molecular biology technique that measures the degree of genetic similarity between pools of DNA sequences Sibley's DNA-DNA hybridization studies placed them close to the lyrebirds; however, anatomical evidence appears to contradict this placement and the true relationship remains unclear.
