The Project began with an attempt to restore puffins to Eastern Egg Rock (pictured at right) in Muscongus Bay, about six miles east of Pemaquid Point. Puffins had nested there until the early 1880's when hunters took the last survivors of this once-flourishing colony. The restoration of puffins to Eastern Egg Rock is based on the fact that young puffins usually return to breed on the same island where they hatched.
Young puffins from Great Island, Newfoundland (where about 160,000 pairs nest) were transplanted to Eastern Egg Rock when they were about 10 - 14 days old. The young puffins were then reared in artificial sod burrows for about one month. Audubon biologists placed handfuls of vitamin-fortified fish in their burrows each day and, in effect, took the place of parent puffins. As the young puffins reached fledging age (the time when birds leave the nest), they received leg bands so they could be recognized in the future.
After spending their first 2-3 years at sea, it was hoped they would return to establish a new colony at Eastern Egg Rock rather than Great Island. Because this was the first time an attempt had been made to restore a puffin colony, the outcome was unknown.
