The puffling season is at its height and locals and visitors are busy helping lost baby puffins out to sea.

A total of 78% of puffin nests on the islands were occupied in a recent survey. Puffins have been hard hit in recent years due to a diminished food supply. It remains to be seen how successful the breeding season will be.

The season’s first puffins arrived on Grímsey island—the only part of Iceland to cross the Arctic Circle—a few days ago and the birds are generally arriving in Iceland significantly earlier each year than they used to.

Puffins are an endangered species, whose numbers have declined largely due to climate change and overfishing.
