Atlantic puffin with sand eels in its bill. Atlantic puffins (Fratercula arctica) feed primarily on fish and breed on the coasts of northern Europe, the Faroe Islands, Iceland and eastern North America, although it spends the winter months at sea. They grow to 34 centimetres high and have distinctive orange bill plates, which are shed after breeding. Photographed in the Wick, Skomer Island, Pembrokeshire, Wales, UK, in July.
