In the spring of 2001 the Department of Environmental Conservation, in partnership with the Wildlife Conservation Society, BioDiversity Research Institute, Natural History Museum of the Adirondacks, and Audubon Society of New York State initiated a study of the natural history of common loons (Gavia immer). It also explored the effects of contaminants and human interactions on loon populations in the Adirondack Park. This research is coordinated with similar efforts throughout North America. Since the North American effort began, over 3,000 common loons have been banded across 13 states and four Canadian provinces.


Look for signs like this on Adirondack
lakes where loons breed.

Data gathered are used by wildlife managers and biologists to ensure that common loons remain an integral part of our State's wildlife heritage.
