Description

In 1979, the U.S. Fish and Wildlife Service initiated a banding project on the Yukon, Porcupine, and Colville rivers where high concentrations of peregrines are located. This report provides the results of the 1981 banding project on the Porcupine River. The objectives of this study were: 1. To locate cliffs occupied by peregrine falcons on the Porcupine River, determine productivity, and band nestlings; 2. To collect prey items, addled eggs, and eggshell fragments from active peregrine nests; and 3. To locate other raptors, raptor nests, and band as many nestlings as possible.
