Native bird and mammal populations in Annerley are being displaced as urban planting practices create favourable conditions for dominant species like the noisy miner.
Background and Contributing Factors
Vegetation changes across Brisbane suburbs, including Annerley, are contributing to the rise of aggressive bird species and the decline of smaller native wildlife. This issue was the focus of a recent BrisScience public lecture held on 2 June 2025 at The Edge, State Library of Queensland.
Presented by Professor Martine Maron and hosted by The University of Queensland, the session detailed how clearing undergrowth and planting tall, nectar-rich trees create favourable conditions for noisy miners and butcherbirds, while reducing shelter for honeyeaters, finches, and small mammals. The BrisScience series has been delivering accessible science talks to the Brisbane public since 2005.
Impact of Noisy Miners on Local Biodiversity
The noisy miner, Manorina melanocephala, is a native honeyeater species known for its aggressive territorial behaviour. According to the Australian Museum, noisy miners often form large colonies and exclude most other bird species—even larger ones such as kookaburras—from areas they occupy. Their breeding season spans from July to December, during which they become especially active and defensive.
These birds thrive in open areas with tall trees and little understorey, conditions increasingly common in suburban parks and gardens. Annerley Park has been identified as a local example where vegetation choices have contributed to these imbalances.
Council Advice and Alternatives for Residents
BCC recognises the impact of noisy miners and advises against feeding or disturbing them, particularly during nesting season. BCC encourages residents to support local biodiversity by planting shrubs that provide cover and food for a wider variety of species.
While grevilleas are common in urban gardens, they are highly accessible to noisy miners. Alternative options such as smaller varieties of native bottlebrush are recommended. Pete’s Hobby Nursery in Lowood is among the nurseries providing suitable plant species and biodiversity-focused guidance.
All native birds and mammals in Brisbane are protected under the Nature Conservation Act 1992. Removing nests or feeding wildlife is discouraged due to its potential to further disrupt ecological balance.
Community Engagement and Ongoing Awareness
Residents are encouraged to support conservation efforts by adjusting garden planting choices and participating in habitat-focused initiatives such as the Land for Wildlife program.
Public lectures like BrisScience aim to expand community understanding of these challenges. As concerns about declining native species persist in areas like Annerley, coordinated efforts between residents, scientists, and local authorities remain central to ecological restoration.
