My research interests include conservation and ecology of raptors. As climate change, habitat loss, and environmental contaminants increasingly impact raptors, it is important to gather baseline information and quantify changes through time. A large part of my research focuses on raptors in the agricultural ecosystem of the Central Valley of California. Raptors rely heavily on this landscape, especially for over-wintering habitat, while at the same time provide valuable natural pest-control services by consuming vertebrate pests. I am interested in determining how raptor habitat-use shifts with available habitat through time, as cropland is increasingly being converted to perennial crops (orchards and vineyards). I am also quantifying rodenticide exposure of diurnal and nocturnal raptors in the agricultural landscape to help develop integrated pest management strategies that maximize benefits from raptors.
