Scientists representing the Adirondack Cooperative Loon Program (ACLP), a partnership of WCS, the Natural History Museum of the Adirondacks (NHMA), New York State Department of Environmental Conservation, BioDiversity Research Institute (BRI), and the Audubon Society of New York, are concerned because data already shows that mercury pollution impacts loons in the Adirondacks and other areas, causing lower reproductive rates. One recent sample of 100 Adirondack loons by BioDiversity Research Institute (BRI) and the US Fish & Wildlife Service revealed that 17 percent of the birds had mercury levels high enough to potentially affect their reproductive success and behavior.
A new federal plan calls for easing regulations proposed by the Clinton Administration to reduce mercury emissions from coal-fired power plants something that scientists say may lead to more bad news.
"We are very concerned that any increase in mercury emissions could spell further trouble for loons in the Adirondack Park and elsewhere in the Northeast," said WCS-NHMA scientist Dr. Nina Schoch, Coordinator for the Adirondack Cooperative Loon Program. "Loons are already suffering from mercury pollution here and in other locations. More mercury will mean greater impacts on northeastern loon populations and their habitats."
Mercury toxicity causes behavioral changes in loons, making them more lethargic, due to its neurotoxic effects. Adult birds incubate and feed their young less, while chicks feed less and ride on their parents' backs less, making them more susceptible to predation and chilling. Mercury levels in loons elevates as you go farther eas
