James Carlson is a Wildlife Biologist for the USDA APHIS Wildlife Services, National Wildlife Research Center (NWRC) in Fort Collins, CO. He has been studying avian ecology for more than 10 years. He began working for USDA in 2002 conducting research on bird damage to plant and animal agricultural operations. Currently his research focuses on the integration of avian and disease ecology to address public health, ecological and economic issues associated with bird use of feedlots and dairies.
