Visiting a peregrine eyrie (1961)

Jay Sumner, Director of MPI, has worked on Montana raptor populations for over 40 years. He located his first active peregrine falcon eyrie in 1961 near Livingston, Montana. Raptor research experience includes studies for the National Park Service, the Montana Fish Wildlife and Parks, the United States Fish & Wildlife Service, the Bureau of Land Management, the Peregrine Fund, and the Bureau of Indian Affairs. Jay took a brief interlude (12 years) from the falcon studies to work with the Craigheads’ on grizzly bear research in Yellowstone Park and  the Scapegoat and Bob Marshall ecosystems.
