The Atlantic puffin, a beloved seabird known for its colorful beak and charismatic presence, is facing a severe population decline, with experts warning that up to 90% of Britain's puffins could be wiped out by 2050 due to climate change and shifts in food supply.
These birds, scientifically known as Fratercula arctica, have a long history, having been around for approximately five million years and surviving multiple ice ages. Britain is home to about 580,000 breeding pairs, representing roughly 9% of the European population.
Recent warnings from the British Trust for Ornithology highlight the precarious future of these birds. While the situation is dire, the puffin's history shows a capacity for recovery. Some populations in Pembrokeshire experienced significant drops between the late 19th and early 20th centuries, only to rebound later, partly due to conservation efforts. Similarly, populations on the Lundy island recovered after predators like rats were eradicated. Fluctuations in sand eel populations, a primary food source for puffins, have also been linked to observed drops and rises in Scottish island colonies during the 2000s and 2010s.
Puffins return to land in May to breed after spending up to eight months at sea. During the breeding season, their coastal habitats are adorned with flowers, and the birds can be seen flying low over the surf, bobbing on waves, and emerging from the sea with sand eels in their bills. Their multi-colored beaks, which change from vibrant in the breeding season to dull gray or brown at sea, are used for catching fish, courtship displays, and signaling health to potential mates. The beaks contain Velcro-like spikes that allow puffins to hold multiple fish, with one recorded individual carrying 61 sand eels and a rockling.
Male puffins are territorial and will defend their burrows, which are typically only about 10 inches wide. They engage in courtship rituals, including touching bills. Puffins are known for their loyalty, mating for life, with the oldest known pair staying together for over 30 years. However, studies suggest they may be more loyal to their nesting burrow than to their mate. After the breeding season, they separate and undertake lengthy migrations across the Atlantic, navigating vast distances to find food before returning to their breeding grounds.
These birds are also powerful excavators, using their beaks as tools to create and maintain their burrows. Their digging activities can significantly alter the landscape of the islands they inhabit. Historically, puffins have been a food source for humans, with archaeological evidence suggesting consumption in the Stone Age and their use as a staple diet in Shetland during the ninth century. Some communities, like those in the Faroe Islands, continue to consume puffins, though methods include fermenting them.
Writer Adam Nicolson, who spent extended periods observing puffins on the Shiant Isles in Scotland, describes them not merely as cute creatures but as tenacious survivors. He emphasizes their remarkable ability to learn and remember ocean maps, currents, and feeding grounds during their solitary winter journeys across the Atlantic, and their adeptness at finding their way back to their colonies. The potential loss of the Atlantic puffin from British waters would represent a significant cultural and ecological blow, though Nicolson notes their resilience suggests they might relocate north if necessary.
