The 1983 peregrine falcon (Falco peregrinus tundrius) nesting survey was a continuing effort to visit active and historic peregrine falcon nesting sites within the Arctic Resource Area (ARA), Alaska (Figure 1). Raptor surveys within the ARA have been conducted for many years: White and Cade (1971), White and Boyce (1978), Ambrose (1980), Dittrick and Swem (1981), Ritchie (1981), Ritchie and Craighead (1982), Swem, Dittrick and Silva (1983) and Dittrick and Moorehead (1983). The Colville and Sagavanirktok Rivers have been annually surveyed by the U.S. Fish and Wildlife Service (USFWS) and Bureau of Land Management (BLM) since the mid 1970s. A portion of the Sagavanirktok River is also under a BLM Habitat Management Plan for peregrine falcons which was implemented in 1979. In addition, many other areas within the ARA are periodically surveyed when funding and manpower is available. The 1983 BLM survey concentrated on the Utukok and Sagavanirktok Rivers. The results of the nesting survey, including cliff locations, banding data and raptor nesting success, are included in this report.
