The Noisy Miner mainly eats nectar, fruit and insects. Most time is spent gleaning the foliage of eucalypts, and it can meet most of its nutritional needs from manna, honeydew and lerp gathered from the foliage. The Noisy Miner does not use a stereotyped courtship display, but copulation is a frenzied communal event. It breeds all year long, building a deep cup-shaped nest and laying two to four eggs. Incubation is by the female only, although up to twenty male helpers take care of the nestlings and fledglings. Noisy Miners have a range of strategies to increase their breeding success including multiple broods and group mobbing of predators. The Noisy Miner’s population increase has been correlated with the reduction of avian diversity in human-affected landscapes. Its territoriality means that translocation is unlikely to be a solution to its overabundance, and culling has been proposed, although the Noisy Miner is currently a protected species across Australia.
