From the moment he captured his first loon on Michigan’s Seney National Wildlife Refuge, Dave Evers has been a champion of wildlife, incorporating innovative approaches to traditional research methods. As the founder, executive director, and chief scientist of BRI, Dr. Evers has made great strides in bringing critical ecological issues to the forefront of our nation’s and the world’s consciousness. He is a brilliant collaborator, working at the highest international levels with world-class scientists, federal and state agencies, renowned universities and research institutes, as well as other nonprofit organizations. As a conservation biologist, he believes it his responsibility to provide decision makers with scientific findings from an unbiased viewpoint. He often testifies or presents scientific results to Congressional committees, state legislative committees, and other regulatory branches of government.
Dr. Evers specializes in research on ecotoxicology with an emphasis on the patterns of oil pollution and methylmercury availability and effects in wildlife, especially birds. Current research projects include assessments of mercury impacts on fish and wildlife across much of North America and in parts of 40 other countries within Africa, Asia, Europe and South America. Through BRI’s Center for Mercury Studies, Dr. Evers oversees several ongoing national and international mercury monitoring networks and database summary efforts, including new projects and partnerships with the International POPs (Persistent Organic Pollutants) Elimination Network and the United Nations Environment Programme.
During his graduate studies, he worked as a field ornithologist for the Michigan Breeding Bird Atlas and as a wildlife ecologist for the Kalamazoo Nature Center. In 1991, he became Executive Director of the Whitefish Point Bird Observatory. In 1998, he founded BRI to further progressive wildlife research and conservation.
Dr. Evers also holds positions as adjunct professor at both the University of Southern Maine, where he teaches ornithology, and the University of Maine at Orono. He is also the adjunct senior scientist at the University of Southern Maine's Center for Integrated and Applied Environmental technology. He has published four books on the Common Loon, the Northwoods, and endangered and threatened species and has published over 80 peer-reviewed publications. He was elected as a National Fellow of the Explorers Club in 2012.
