Puffins thrived on the small rocky island called Eastern Egg Rock off the coast of Maine for millennia before they were hunted to extinction in the 1880s. In an effort to repopulate the island, a group of chicks were relocated there from Newfoundland in the 1970s and then monitored ever since. In 2026, researchers studied the gaps between the island's boulders – the hidden places where puffins make their nests, and they recorded 200 separate places where puffins were delivering fish to their babies. This beat the previous record of 188 nests, and it demonstrated that these puffins have grown into a viable and vibrant community. This is the southernmost puffin colony in North America.
