Skomer Island, Wales
Atlantic puffins bash beaks. Skomer has the biggest puffin colony in southern Britain, with more than 52,000 birds recorded in 2026. The puffins visit the island between April and July to breed.
Billing (sometimes called "clattering") is an example of puffin social behaviour. They tap their beaks together to reinforce pair bonds or re-establish their hierarchy after a long winter apart at sea.
