Swooping in for a landing, an Atlantic puffin brings a meal for its chick on Scotland’s Treshnish Isles.
Puffin parents make up to eight food runs a day; each bird can grip 20 or more fish in its beak.
Peeking from its burrow, a puffin snips off a bloom to dress up its temporary home on Skomer Island, where 6,000 pairs breed. Burrows usually extend several feet or more to keep egg and chick safe.
Chicks are rarely seen, staying hidden for six weeks or so until flying off one night.
From April to August puffins take over fog-swept cliffs at Hermaness Reserve. Many return to the same partner and burrow.
What exactly a puffin does in winter remains a mystery.
