Evidence-based information about uk puffin: seabird welfare and climate impacts on prey for animal welfare improvement.
Puffin chicks that cannot be provisioned with sufficient sand eels starve in their burrows - a welfare outcome entirely dependent on adult foraging success. When warming seas drive sand eels deeper or further from colonies, adult puffins must work harder for less food. Breeding success has collapsed at some colonies, representing welfare failures for thousands of chicks.
