The team's long term goal is: Examine the causes, fates, exposures, biological accumulation, and adverse effects (including sublethal effects) of environmental contaminants on animal (largely bird) populations.
Systematic Approach to Understanding Tree Swallow Health in the Great Lakes Region—Science to Inform Restoration
Four papers by U.S. Geological Survey (USGS) scientists document tree swallow ( Tachycineta bicolor) chemical exposure, physiological responses, and reproductive success in the Great Lakes region. These studies were designed to understand if there are health threats to swallows from contaminant exposure, and to provide resource managers with information about the actual as opposed to the perceived...
Birds as Indicators of Contaminant Exposure in the Great Lakes
Objectives: 1. Use tree swallows and colonial waterbirds in the Great Lakes to evaluate contaminant Exposure (geographic and spatial) 2. Trends through time (temporal) 3. Effects (reproductive, physiological, genetic) 4. Monitor cleanup actions

Emerging Contaminants Might Affect Tree Swallow Reproduction
Contamination from commercial products such as nonstick cookware and stain repellents could reduce the reproduction of tree swallows nesting in Minnesota and Wisconsin.
