Population dynamics of the common loon (Gavia immer) associated with mercury-contaminated waters in northwestern Ontario / J.F. Barr.: CW69-1/56E-PDF
"Common Loons on lakes of the Wabigoon-English River system, northwestern Ontario, were adversely affected by unnatural, unpredictable water-Ievel fluctuations and turbidity, and by mercury contamination. Extensive, man-induced water-level changes resulted in increased desertion and predation of clutches. Increasing turbidity resulted primarily in a decrease in the number of potential territories occupied. A strong negative correlation existed between the successful use of territories by breeding loons and mercury contamination"--Abstract.
