Polygamous by nature, the male Western Bowerbird courts multiple females during the breeding season. The male constructs an elaborate bower of sticks to attract females, which he decorates with an array of green and white objects. These may include natural items like berries and bones, as well as man-made trinkets. The male performs ritualized dances and calls to entice the female, showcasing his bower and decorations. Females are solely responsible for nest-building, incubation, and chick-rearing.
The male Western Bowerbird advertises his bower with distinctive calls, which are part of the courtship display to attract females.
The female builds a nest, a shallow cup of twigs, often situated in a tree or shrub, sometimes utilizing a clump of mistletoe. The clutch typically consists of one or two eggs, which are green to buff in color with dark scribble patterns. The duration of the incubation period remains unknown.
