I am interested in the impacts on environmental contaminants on birds. Currently, I am investigating mercury contamination in songbird populations along Fountain Creek. Terrestrial birds adjacent to contaminated waterways can have similar levels of mercury accumulation to birds eating fish directly from the aquatic ecosystem. However, there is a large amount of variation in the exposure levels both within and between species. I am examining the ecological, behavioral, and molecular factors that influence inter- and intra-specific variation in bioaccumulation of mercury. I am also interested in the impacts that neurotoxins like mercury have on bird behavior. In particular, I am currently examining the effects of developmental mercury exposure on song learning in passerine birds.
