In the United States Environmental Protection Agency's (USEPA) current pesticide risk assessment process, a pair of laboratory avian reproduction tests with mallards (Anas platyrhynchos) and northern bobwhites (Colinus virginianus) is conducted to evaluate how dietary pesticide exposure affects a standard suite of reproduction endpoints (USEPA 1996). This report was prepared for the U.S. Environmental Protection Agency by ICF International under contract. Additionally, we gratefully acknowledge the programs and individuals mentioned below for their contributions to this project.
