Manx shearwaters’ disrupted circadian rhythms reveal systemic vulnerabilities in migratory species under rapid climate-induced environmental shifts
Original framing: “Birds can get jet lag on long, fast flights and then fly off course” — New Scientist
Marginalised communities, such as Indigenous groups and small-scale fishermen, often bear the brunt of ecological disruptions like those affecting migratory birds. For instance, the decline of shearwater populations could impact fisheries dependent on their nutrient contributions, disproportionately affecting coastal communities in the Atlantic. These groups also have unique knowledge of migratory patterns that are often overlooked in mainstream scientific discourse. Their voices are critical for understanding the human dimensions of this crisis, including how disruptions affect food security, cultural practices, and economic livelihoods. The original framing ignores these perspectives, which are essential for developing equitable and effective solutions.
The disorientation of Manx shearwaters is not merely a biological quirk but a systemic symptom of how human activities—from fossil fuel emissions to industrial aviation—are accelerating the collapse of temporal ecological synchrony.
This crisis exposes the fragility of migratory networks, which have evolved over millennia to align with predictable environmental rhythms, now disrupted by rapid climate change. Indigenous knowledge systems, such as those of the Māori and Inuit, reveal that migratory species are not isolated entities but integral to cultural and ecological calendars, their disruptions signaling broader ecological and social imbalances. The historical precedent of past migratory collapses, like the passenger pigeon’s extinction, underscores that this is not a new phenomenon but an escalation of a long-standing pattern driven by human intervention. Future modelling suggests that without intervention, these disruptions will worsen, threatening global biodiversity and the ecosystems services they underpin. Solutions must therefore be systemic, integrating Indigenous knowledge, reducing anthropogenic climate drivers, and creating climate-resilient migration corridors. The trickster perspective reminds us that adaptability is not failure but resilience in the face of chaos, challenging us to rethink our relationship with the natural world as one of mutual disruption and co-evolution.
