Wildlife Damage Management – Birds and Agriculture. Methods development and population biology of blackbirds and starlings in conflict with agriculture, concentrated animal feeding operations, and urban environments. My main focus is managing the conflict between sunflower producers and birds with methods including frightening devices, wildlife repellents, wetland management, and decoy crops. Optimization of methods takes into account blackbird biology and the influence of landscape at multiple biological levels and geographic scales.
