The
National Audubon Society started Project Puffin in 1973 in an effort to
learn how to restore puffins to historic nesting islands in the Gulf of
Maine. At that time, literally all the puffin eggs in Maine were in two
baskets - Matinicus Rock and Machias Seal Island. Although puffins are
not an endangered species (they are abundant in Newfoundland, Iceland,
and Britain), they are rare in Maine. The two surviving colonies were very
vulnerable to a disaster such as an oil spill, or accidental establishment
of predators such as rats or mink.
The Project began with an attempt to restore puffins to Eastern Egg Rock 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.
Between
1973 and 1986, 954 young puffins were transplanted from Great Island to
Eastern Egg Rock and 914 of these successfully fledged. Transplanted puffins
began returning to Eastern Egg Rock in June of 1977. To lure them ashore
and encourage the birds to explore their home, wooden puffin decoys were
positioned atop large boulders. These were readily visited by the curious
young birds, which often sat with the models and pecked at their stiff
wooden beaks. The number of young puffins slowly increased. In 1981, four
pairs nested beneath boulders at the edge of the island and the colony
has since increased to 37 pairs in 2001.
In 1984, National Audubon Society and the Canadian Wildlife Service began a similar puffin restoration project at Seal Island National Wildlife Refuge in outer Penobscot Bay (6 miles east of Matinicus Rock). Hundreds of puffins once nested at this large mid-coast Maine puffin colony, but hunting for food and feathers decimated this colony by 1887. Between 1984 and 1989, 950 puffin chicks were transplanted from Great Island Newfoundland, to Seal Island and 912 of these fledged. Seven pairs returned to nest in 1992 and the colony has rapidly increased to 145 pairs by 2001.
National Audubon biologists have also developed techniques for managing terns and storm-petrels, species that also have declined in recent years. Techniques such as gull and vegetation control, use of tern decoys, and tape recordings of courtship sounds broadcast from the islands are helping to restore colonies. These efforts are so successful, that in recent years, Eastern Egg Rock has become the largest Common, Arctic and Roseate Tern colony in Maine. These techniques have also helped to protect the terns at Matinicus Rock and establish new tern colonies at Seal Island, Stratton Island (Saco Bay), Jenny Island (Casco Bay), and Pond Island (Kennebec River). These methods are also proving useful for helping endangered seabirds in the Galapagos Islands of Ecuador (Dark-rumped Petrels), California (Common Murres) and Quebec (Northern Gannets).
Restoration of seabird colonies takes years of persistent work, since so many factors influencing success are beyond the control of researchers. For example, young puffins must find ample food and clean waters while avoiding predators. Unfortunately, oil spills, depleted fish stocks, entanglement in fishing nets and predation by gulls decrease the number of surviving birds. Considering these odds, the establishment of new puffin and tern colonies through active management is especially exciting.
Project Puffin has a year round staff of seven which increases to include more than 50 biologists and researchers during the seabird breeding season in spring and summer.
The project is based in Ithaca, New York
and the Todd Wildlife Sanctuary on mid-coast Maine.
