Habitat: Wetter forests and woodlands, and nearby open areas
Biology: Have a large repertoire of calls, including whistles, buzzing, rattling and hissing, as well as mimicry. The male also gives a loud "weeoo" sound.  The male Satin Bowerbird is perhaps the best known and well documented of all the bowerbirds in Australia. This fame partially stems from its practice of building and decorating a bower to attract females. The male bird builds and decorates a bower to attract females. The bower consists of two parallel walls of sticks, built on the ground, and is used as a courtship arena during the breeding season. It is decorated with bright blue coloured objects that the bird collects; pegs, drinking straws, bottle tops are among the favourite stolen items, while bright blue feathers, flowers and brown snail shells, make up the majority of decorations away from human habitation. A mixture of chewed vegetable matter and saliva is used to paint the walls of the bower. The bower owner meticulously maintains the bower throughout the year. On the arrival of a female, the male Satin Bowerbird leaps into a ritualised display of exaggerated movements, such as strutting and bowing, with wings outstretched and quivering, and accompanied by a variety of mechanical-sounding calls and mimicry.  One of the bower decorations is usually carried in the male's bill. If impressed, the female moves into the bower avenue for mating and then leaves to perform the nesting duties on her own, while the male readies himself for courting more prospective females. The female places a loose nest of sticks in a tree or bush, up to 30 m - 35 m above the ground. Breeding Season: September through to about February Clutch size: 2 to 3 Incubation: 21 days Time in nest: 21 daysSatin Bowerbirds feed mostly on fruits 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.
