Feeding ecology and diet

While typically omnivorous, several bowerbirds are more specialized in having a predominantly fruit diet supplemented by arthropods and other animals such as worms, frogs, skinks, and birds. Flowers, leaves, sap, and few seeds may also be eaten. Unlike birds of paradise, bowerbirds do not use their feet to hold and manipulate food.

Bowerbirds do not digest seeds but act as true seed dispersal agents to the plants on which they feed. The traditional nature of bower sites suggests that a local abundance of food plants might result from the germination of seeds defecated by the birds. Catbirds store or cache fruits about their territories, and males of some polygynous species do so about their bower sites.
