[[Image:Satinbowerbird.JPG]] '''Common Name:''' Satin Bowerbird<br> '''Scientific Name:''' Ptilonorhynchus violaceus '''Size:''' 10½ - 13 inches (27-33 cm) '''Habitat:''' Australia; endemic--common in rainforest and tall wet sclerophyll forest in eastern Australia from southern Queensland to Victoria. There is also an isolated population in the Wet Tropics of north Queensland. '''Status:''' Least Concern. '''Global population:''' unknown. '''Diet:''' Fruit throughout the year. During summer (breeding) the diet is supplemented with a large number of insects, while leaves are often eaten during the winter months. '''Nesting:''' Like all bowerbirds, the Satin Bowerbird shows highly complex courtship behavior. Mate choice in Satin Bowerbirds has been studied in detail by a group of researchers at the University of Maryland, College Park. Males build specialized stick structures, called bowers, which they decorate with blue, yellow, and shiny objects if these are available, including berries, flowers, and even ballpoint pens, drinking straws and other discarded plastic items. As the males mature they use more blue objects than other colors. Females visit these and choose which male they will allow to mate with them. In addition to building their bowers, males carry out intense behavioral displays called dances to woo their mates, but these can be treated as threat displays by the females. Nest building and incubation are carried out by the females alone. Recent research has shown that female mate choice takes place in three stages: * Visits to the bowers, before nests have been built, while the males are absent * Visits to the bowers, before nests have been built, while the males are present and displaying * Visits to a selection of the bowers, after nests have been built, leading to copulation with (typically) a single male. Experimental manipulations of the ornaments around the bowers have shown that the choices of young females (those in their first or second year of breeding) are mainly influenced by the appearance of the bowers, and hence by the first stage of this process. Older females, which are less affected by the threatening aspect of the males' displays, make their choices more on the basis of the males' dancing displays. It has been hypothesized that as males mature their color discrimination develops and they are able to select more blue objects for the bower. It is not yet known whether this description would also hold good for other species of bowerbird. Males are uniformly colored in a deep shiny blue. '''Cool Facts:''' A rare natural intergeneric hybrid between the Satin Bowerbird and the Regent Bowerbird is known as Rawnsley's Bowerbird.
