A survey was conducted in the Spring of 1975, with supporting data from the previous year, to search for nests and to determine productivity of the American Peregrine Falcon (Falco peregrinus anatum). Eleven sites with pairs were in located 1974 and 1975. Although 4 river eyries failed to produce young, it appears that 6 of 7 nests located in the mountains were successful. Prey species of peregrines are listed
