Skomer Island, off Wales, hosts 350,000 puffins in a thriving colony, thanks to burrows and lack of predators, despite avian flu impacts elsewhere.
Puffin population rises on Skomer Island
The island of Skomer, located off the coast of Wales, is home to approximately 349,663 pairs of English puffins, a significant increase of 10.6% compared to the 2011 count. This growth highlights the success of conservation efforts on the island.
Skomer’s unique bird numbers
Skomer is not only a haven for puffins but also hosts a record number of northern fulmars, with 52,019 counted in the latest census. This figure marks a notable increase from the previous year’s count of 43,626.
Puffins and avian jet lag
A study from the University of Oxford based on 20 years of GPS data reveals that puffins experience a form of "jet lag" that affects their solar orientation. This results in heading errors of up to 15 degrees when they return to their nesting sites.
Skomer’s natural sanctuary status
Skomer is recognized as a Site of Special Scientific Interest and the only marine nature reserve in Wales. This status necessitates careful management of the island’s land to protect its unique ecosystem and wildlife.
Life beneath the surface
The puffins on Skomer live in underground burrows, which serve as their nests and shelters. These burrows protect them from predators and provide a safe environment for incubating their eggs and raising their young.
Skomer’s ecological advantages
The absence of rats and other terrestrial predators is a key factor in the success of the puffin colony on Skomer. In contrast, other Welsh colonies such as those on Grassholm have suffered significant declines due to factors like avian flu.
