Manorina melanocephala, commonly known as the Noisy Miner, is native to eastern and southeastern Australia. Its distribution spans from northern Queensland, through New South Wales, and down to Victoria and southeastern South Australia.

The Noisy Miner typically inhabits open woodland, eucalypt forests, and urban areas. It prefers environments with sparse understorey and can often be found in parks and gardens, particularly those with native eucalyptus trees. The species thrives in environments with moderate temperatures and access to both open spaces and tree cover.

As a social and aggressive bird, the Noisy Miner plays a significant role in its ecosystem by influencing the composition of bird communities through its territorial behavior. It feeds on nectar, fruit, and insects, often displacing other bird species to dominate its chosen habitat. This species has adapted well to human-altered landscapes, contributing to its expanding presence in suburban areas.
