25 NESTS IN OUR 25TH YEAR
Project Puffin celebrated its 25th season this summer as the restored Egg
Rock puffin colony increased to a record high of 25 nests. Eleven of the
breeding puffins this summer were among the original 954 chicks transplanted
to Egg Rock from Newfoundland between 1973-1986. They are now joined by
increasing numbers of native puffins from Egg Rock and other Maine puffin
colonies.
The original puffin population at Egg Rock was decimated by excessive
hunting for food and feathers that led to the loss of the colony by the
late 1880s. Puffins recolonized Eastern Egg Rock in 1981-eight years after
the first puffin chicks were reared and released at the island. In 1979,
an effort was begun to boost the small colony on Matinicus Rock where puffins
had persisted since the beginning of the century. The Seal Island National
Wildlife Refuge puffin restoration began in 1984 (see Seal
Island Update.)
The
restored puffin colony at Eastern Egg Rock began with four pairs in 1981
and then leveled off at about 16 pairs for nearly a decade before increasing
to 19 pairs in 1996, 22 pairs in 1997 and 25 pairs in 1998. This is especially
heartening since translocation of young chicks ended in 1986 and all recent
colony growth is due to unbanded birds which are either young produced
at Egg Rock or at neighboring islands. By 1998, 77 percent of the known
Egg Rock breeders were unbanded birds which had likely hatched at the island
or at other puffin colonies in the Gulf of Maine.
While the Egg Rock puffin colony is small compared to huge colonies
in Newfoundland, Iceland, Scotland and elsewhere, this tiny island has
demonstrated that with enough persistence and care, restoration of lost
seabird communities is possible. This is important because too often human
enterprise results in the loss of colonies, leading to reduced ranges and
increased vulnerability to catastrophes such as chemical spills, disease,
extreme weather and predation.
ROSEATE TERNS CONTINUE 12-YEAR
INCREASE
Roseate Terns, a federally endangered species, increased their numbers
to 144 nesting pairs at Egg Rock this summer which represents more than
half of the Roseates nesting in Maine. Roseate Terns recolonized Eastern
Egg Rock in 1981 and their numbers have continued to rise as Common Tern
numbers climb. Both species nested at record levels this summer, with the
Common Tern population reaching about 1,400 pairs. It is likely that the
Egg Rock Roseates once nested at the island within a larger colony of Common
and Arctic Terns, but disappeared more than 60 years ago as Herring and
Great Black-backed Gull populations increased and displaced the nesting
terns. Both Roseate and Common Tern colonies
at Egg Rock achieved excellent breeding success this summer as Roseates
fledged at least 121 young and Common Terns produced about 1,600 fledglings!
