Wild Puffin Welfare and Colony Decline

Atlantic puffins face mounting welfare challenges from prey fish decline, plastic ingestion, and climate-driven changes to prey distribution that leave chicks underfed.

Key Facts

Puffin colonies have declined significantly across the UK and Norway since the 1990s
Puffin chicks (pufflings) are fed primarily on sand eels, which have declined due to warming seas
Adult puffins fly up to 100km per foraging trip to find sufficient prey fish during chick-rearing
Plastic ingestion has been documented in puffins across the North Atlantic
Puffins are highly site-faithful, returning to the same burrow year after year

Welfare Considerations

Puffin welfare is intimately linked to the health of cold-water fish populations. As sand eels shift their distribution northward with warming seas, puffin parents must fly increasingly long distances to provision chicks. Chick starvation during poor prey years causes significant suffering before death. On land, colony disturbance from tourism and predation by introduced species such as rats reduces breeding success. Island rat eradication programs have shown dramatic improvements in seabird breeding success and are among the most cost-effective wildlife welfare interventions available.

What You Can Do

Support island restoration programs that eradicate invasive predators from puffin nesting islands
Donate to seabird monitoring programs that track puffin population trends
Reduce single-use plastic consumption to lower marine plastic pollution affecting seabirds
Advocate for climate policy that slows ocean warming and protects cold-water prey fish distributions
