The polygamous male builds a tower-like maypole-type bower, with a central pole of twigs surrounded by a dish of moss with raised walls approximately 1 meter in diameter. He decorates the twigs of the maypole with flowers, fruits, insects and other objects. The diet consists mainly of fruits and insects. Bowerbirds are positioned roughly in the middle of the continuum of the transfer effect phenomenon observed among the different bowerbird species, whereby brilliant plumage evolves to more drab colors, while ornamentation is transferred to the behavior of creating elaborate bowers to demonstrate robust health instead.
The Macgregor's Gardener Bowerbird is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.
