A Step Too Far: Culling a Native Australian Honeyeater, the Noisy Miner (Manorina melanocephalis), for ‘Conservation’: Biases, Contradictions, and Myth-Making

Birds of the Anthropocene have to adapt to changing and often very unfavourable conditions, among them habitat fragmentation or outright habitat loss. Many organisations worldwide are deeply committed to stemming the tide of extinctions of native species and maintaining biodiversity. The question is how far scientists and practitioners are willing to go to achieve conservation goals in situations that are not entirely resolved, are contradictory, or involve dubious claims about alleged causative agents. The noisy miner, Manorina melanocephala, has been painted as such a causative agent in the decline of small woodland birds. The noisy miner is a highly successful, flexible, and socially complex small native Australian honeyeater (woodland bird). As will be shown in a new data analysis, the noisy miner also ranks highly in cognitive abilities. Despite its status as a native species, a protracted campaign against the species has led to government policies permitting its culling in New South Wales due to its alleged ‘overabundance’ and ‘harmful’ impact on small woodland birds. As a consequence, noisy miners can now be shot legally and have been culled in their thousands in the last decade. Allegedly, these actions have been taken for conservation purposes. This paper raises significant doubts about the claims against this species, and the methods and ethics of how a native species can become the sole bearer of the ills of the Anthropocene. This paper exposes bias or misinterpreted evidence and shows how myth-making is possible in modern science and how language can purposefully mislead the public via characterisations of avian behaviour. In essence, this paper is a case study of ethical issues in science: about the degree and type of intervention, and how far we are willing to go in the name of conservation, particularly when based on spurious or contradictory evidence and at the cost of native animals.
