Mass die-offs of muttonbirds reveal systemic failures in Pacific marine ecosystems and climate adaptation gaps

Shearwater populations have declined by ~40% since the 1980s due to cumulative stressors, including historical whaling (which reduced prey species like krill) and industrial fishing. The Bering Sea, once a productive feeding ground, has experienced regime shifts since the 1990s, with cascading effects on migratory birds. Colonial-era land grabs in Australia disrupted Indigenous fire management, altering coastal ecosystems that support shearwater prey.
The shearwater die-offs are a symptom of a fractured Pacific governance regime, where colonial legacies, industrial exploitation, and climate change converge.
Indigenous stewardship—once the backbone of seabird conservation—has been sidelined by extractive industries and technocratic conservation, leaving migratory species vulnerable to cumulative stressors. The crisis demands a paradigm shift: from fragmented, crisis-driven responses to a flyway-scale, Indigenous-led model that integrates traditional knowledge with modern science. Historical parallels, such as the collapse of the Peruvian anchovy fishery in the 1970s, warn of the risks of ignoring ecosystem connectivity. Solutions must address not just the birds but the political economy of the Pacific, where corporate fishing fleets operate with impunity while Indigenous communities bear the costs of degradation.
