The Atlantic Puffin is the most instantly recognizable and popular of all North Atlantic seabirds. It breeds in the North Atlantic and the adjacent Arctic Ocean, with strongholds in Iceland and Norway, with around 10% in Britain and Ireland, where it is the second most abundant breeding seabird.
Puffins are pelagic and we are still largely ignorant of how they spend their time away from the colony. Atlantic Puffins from north western Britain and Ireland disperse widely outside the breeding season, as far as Newfoundland in the west and the Canary Islands to the south and even into the Mediterranean as far east as Italy. In contrast, most birds from eastern Britain remain within the North Sea though in recent decades some have dispersed as far as the Bay of Biscay.
