Resource use of arctic peregrine falcons along the Colville River, Alaska


September 2010 - December 2015


The Colville River Special Area (CRSA) was designated in 1977 to protect nesting and foraging habitat of the then-endangered Arctic peregrine falcon. The objectives of this project are to (1) summarize and evaluate existing CRSA peregrine nesting data to assess nesting habitat use and related productivity, and (2) implement additional data collection efforts focused on assessing nesting area occupancy related to habitat and other factors associated with productivity. This information will help inform management of the CRSA.
