This joint 1975 U.S. Bureau of Land Management and U.S. Fish and Wildlife Service report evaluates raptor populations in various parts of Alaska including the Noatak River area. Between 19-30 June 1975 the authors floated the Noatak River from the mouth of Aniuk River to that of Kelly River. In addition, they conducted an aerial survey on July 4 and 5. The main purpose of the investigation was to determine the present breeding dispersion, density, and reproductivity of cliff-nesting raptors and bald eagles. No peregrines were observed along the Noatak. Three species of raptors (gyrfalcon, golden eagle, and rough-legged hawk) occupied cliffs along the Noatak River. Shore birds and passerines constituted the majority of the avifauna. The appendices contain an annotated list of bird species encountered, as well as observations on large mammals.
