1991 Noatak River raptor survey
Wildman AM. 1991. 1991 Noatak River raptor survey. National Park Service. Kotzebue, AK
The raptor survey of 1991 represents the sixth consecutive year that the mainstream of the Noatak River was surveyed for the presence of nesting raptors. The first survey, conducted in 1986 by Amaral and Gardner of the Endangered Species Division of the U.S. Fish and Wildlife Service, Alaska, was initiated to document the occurrence of cliff-nesting raptor species and their susceptibility to disturbance by recreational visitor use. Of primary interest was the likely existence of a small population of nesting Arctic Peregrine Falcons. The first documentation of a peregrine eyrie occurred in the year prior, 1985, and this finding prompted the survey. Surveys were undertaken in subsequent years by various researchers; J.A.K. Ball 1987, D.F. Whitacre 1990, and A.M. Wildman et al. 1991. The purpose of each survey was to monitor the occupancy and, if able the productivity of known and new nest sites along the Noatak River.
