Atlantic Puffin Welfare: Ocean Changes and Conservation
Species and Population Status
The Atlantic puffin (Fratercula arctica) is an iconic seabird that breeds in burrows on rocky coasts and offshore islands. The UK holds approximately 580,000 pairs, primarily on Shetland, Orkney, St Kilda, and the Farne Islands. Despite appearing abundant, puffin populations have declined significantly: the UK lost approximately 10% of its puffin population between 2000 and 2015, and populations in key colonies are declining further.
Food Supply Welfare Challenges
Puffins feed primarily on sandeels (Ammodytes spp.) during the breeding season, which they carry in bundles to feed chicks. Sandeel abundance is strongly influenced by sea surface temperature: warmer seas reduce sandeel availability and shift their distribution. Climate change is fundamentally altering puffin food chains. When sandeels are scarce, puffins bring lower-quality alternative prey (sprat, other small fish) that is less nutritious for chicks, reducing fledgling success.
Breeding Colony Welfare
Breeding success varies enormously between years and colonies depending on sandeel availability. In poor years, large numbers of chicks starve before fledging. Adults that cannot find sufficient food may abandon their chick (trading offspring welfare for parental survival and future reproductive opportunities). Long-term monitoring at key colonies (RSPB, JNCC seabird monitoring programme) documents productivity trends and welfare over time.
Migration and Wintering Welfare
Outside the breeding season, puffins spend 6-7 months at sea in the North Atlantic, coming ashore only to breed. They are vulnerable to: oil pollution (a single spill can kill thousands); entanglement in fishing gear; and depletion of prey by commercial fishing. Mortality at sea is high and partially responsible for population declines.
Conservation Actions
Conservation measures: protection of key breeding colonies from disturbance; reduction of competing fisheries (sandeel quota management in UK waters); climate change mitigation (reducing greenhouse gas emissions protects marine ecosystems long-term); oil spill response planning; and monitoring population trends through standardised monitoring programmes. The RSPB's work at key colonies and advocacy for sustainable fisheries management are the most impactful welfare and conservation actions.
