MASSACHUSETTS
Official State Classification: Rare
This classification requires that "all reasonable effort be made to
avoid adversely affecting" the loon.
Historical Perspective:
The noted ornithologist Edward Howe Forbush stated that "probably
the common loon once bred in suitable locations throughout
Massachusetts." By 1925, he considered them extirpated from the
state after being unable to learn of any nesting locations in the early
1900s.
Quabbin Reservoir, a 25,000 acre lake used as the source of drinking
water for metropolitan Boston, was constructed and filled by 1946.
Loons were suspected to be nesting there on and off over the next
several years. Meanwhile, nesting was documented on a nearby lake
in 1943. Finally, in 1975 nesting was confirmed on Quabbin.
Present Population:
The Metropolitan District Commission has kept records on the
numbers of loons on Quabbin since 1975. In 1988, there were six
pairs on Quabbin and four others on four public drinking water
reservoirs. Nine of the ten pairs nested in 1987 and seven chicks
were raised to fledging.
Prospects:
The prospects for Massachusetts look pretty good. According to Brad
Blodget, state ornithologist for the Division of Fisheries and Wildlife,
there seems to be plenty of suitable habitat for loons on surface
water reservoirs closed to boating. A protection plan has been
formulated for the loons on Quabbin and the publicity generated by
the project should make future protection programs more effective.
The only clouds on the horizon are the ones carrying acid rain. Unless
improvements in the acid rain situation are made soon, the Quabbin
Reservoir, according to Dick Cronin, director of the Department of
Fisheries and Wildlife, will be acidified by 1995 and loons on that
water body will suffer.
Private Loon Organization:
The Massachusetts Audubon Society, the Massachusetts Division of
Fisheries and Wildlife, and the Metropolitan District Commission
jointly sponsor a conservation and management program.
VERMONT
Official State Classification: Endangered
Historical Perspective:
While there are no solid historical baseline population estimates for
loons in Vermont, early naturalists reported loons breeding on most
of Vermont's larger lakes. Records clearly indicate loons nested on
Dunsmore and Bomoseen Lakes and Mallets Bay of Lake Champlain,
all lakes where no loons have nested for at least thirty years. In
1978, the Vermont Institute of Natural Sciences (VINS) staff and
volunteers surveyed sixty-eight lakes and found only sixteen active
loon nests. Only fifty-six adults were seen.
Present Population:
VINS has surveyed Vermont lakes for loons each year since 1978.
The number of nesting pairs reached a high of nineteen in 1982, but
dropped to a low of eight the next year. In 1987, twelve nesting
pairs on eleven different lakes produced eleven fledged young. A
total of forty-five adults were seen on Vermont lakes during the
1987 summer season. There has been a disturbing number of lakes
that have been used only one, two or three years by nesting loons.
Thirteen lakes with nesting loons in 1978 and 1979 lost their pairs
by 1986n87, while only four lakes gained pairs during this period.
Almost all of the lakes used by loons in Vermont are in the
northeastern corner.
Prospects:
There are a number of lakes with suitable loon habitat that are
vacant at present. Since the low year of 1983, the population has
been increasing slowly and Chris Rimmer, coordinator of the VINS
loon project, is cautiously optimistic that it will continue. This small
population seems to be isolated from populations in New Hampshire
and New York, which may limit the number of new birds coming into
the population.
Private Loon Organization:
The Vermont Institute of Natural Sciences conducts an annual loon
survey, limited research and public education programs on behalf of
loons.
