Mating takes place in the avenue of the bower, and the male may mate with several females in a single season. Only the female builds a nest. This is a shallow, saucer-shaped construction of twigs and dry leaves, placed 10–15m above the ground in the upright outer branches of a tree.
Male bowerbirds with the best decorated bowers find themselves with the most females. Mating takes place in the bower, but the female then leaves to raise the babies on her own. She lays her eggs in a saucer-shaped nest which she builds in a tree, well above the ground.
Some bowers built by male satin bowerbirds have been maintained for more than 30 years, and both males and female satin bowerbirds are known to live 20 to 30 years.
Male bowerbirds decorate their nests with bright blue objects in an attempt to nab the perfect partner. The satin bowerbird is thought to go for blue objects because it reflects its colouring, which in turn entices the right mate.
Are bower birds endangered?
Male satin bowerbirds are known to destroy and steal from the bowers of one another. The quality of a male's own bower does not predict how often they will destroy others. However, males who exhibit more aggression by attacking others at feeding sites tend to destroy competitor bowers more frequently.
Magpie. Perhaps one of the best-known examples of a bird that likes shiny things, the magpie has entered into popular folklore as an animal that, given a chance, will attempt to steal a trinket or similar object.
As with species in which physical male–male competition is prevalent, sex differences in the life history traits of one well-studied bowerbird, the satin bowerbird (Ptilonorhynchus violaceus), are evident, including differences in growth patterns and developmental activity. Female satin bowerbirds begin to reproduce at

Satin bowerbirds are a protected native species. EPA Manager Regional Operations North Coast Benjamin Lewin said the killing of native birds, whether through intentional or reckless pesticide misuse, was a serious offence.
The study suggests that males use the flock mimicry to deceive females into believing there is a predator nearby and thus preventing them from breaking off courtship or leaving before copulation, thereby increasing their chances of successfully mating.
Although better known for their bower building and bower decoration skills (e.g. Frith & Frith 2004), spotted bowerbirds Ptilonorhynchus maculatus are also proficient vocal mimics, typically mimicking over a dozen heterospecifics and other environmental noises.
Male bowerbirds use their intelligence to impress the females, constructing elaborate structures called bowers to attract mates. They are not on master builders, but also accomplished artists. Males of some species decorate their bowers lavishly with flower petals and sparkly manmade objects.
Bowerbirds have a wide range of vocalizations. Some utter loud, harsh notes or hiss, cackle, and chatter. The calls include mimicry of other birds' calls, sounds from their environment, and sometimes human-made noises. Both male and female can mimic the sound of predatory birds.
Bowerbirds were long and widely considered most closely related to the birds of paradise (Family Paradisaeidae) (Frith and Beehler, 2004; Frith and Frith, 2011). They also suggest that major lineages within the bowerbirds originated about 24 Mya.
