Like most other bowerbirds, the male builds and maintains a bower over several years. Males do not grow their adult plumage for at least five or six years, during which time they wander, learn the social hierarchy of mature males, and practice building bower-like structures. Upon maturity, a male establishes his bower site, builds his structure, and spends much time decorating it. He may steal decorations from his neighbours, and defend his possessions from other males. During the breeding season, generally August through December, the male perches at his bower and produces a number of vocalizations, which attract females.
