In 1973, Dr. Stephen Kress launched Project Puffin, an effort to reestablish a puffin colony on Eastern Egg Rock. Prior to this effort, no puffin colony had been recorded on the island since 1906. To reestablish the puffin population, Kress led a group of ornithologists based on Hog Island to transport chicks from an island in Newfoundland. The group reared chicks in burrows they constructed, before releasing the puffins in hopes that they would return to the island to rear their own chicks.
