Última In Situ Behavioral Response of Common Loons Associated with Elevated Mercury (Hg) Exposure Ecology and Society Nocera, Joseph J; Acadia University; 023758n@acadiau.ca; Taylor, Philip D; Acadia University; ptaylor@resalliance.org. Common Loons (Gavia immer) in Nova Scotia, Canada have the highest blood mercury (Hg) concentrations of any loon population in North America. Previous studies have shown that exposure to varying levels of Hg in prey is associated with changes in pre-nesting adult behavior. We report here the first association of sublethal blood Hg contamination with changes in behavior of Common Loon young. As Hg levels in their blood rise, the amount of time that chicks spend brooding (by back-riding) decreases (P = 0.004) and time spent preening increases (P = 0.003). The sum increase in energy expenditure is not being compensated for with expected increases in feeding rates or begging. We suggest that such altered time-activity budgets may disrupt the energetic balance...
