The Status of the Bald Eagle and Osprey in Grand Teton National Park, Yellowstone National Park and Vicinity

Abstract

Yellowstone National Park funded a research study conducted by Jon Swenson from 1972 through 1974 on the ecology of the bald eagle (Haliaeetus leucocephalus) and osprey (Pandion haliaetus). The present study was initiated to further the information on the ecology of the bald eagle and osprey in Grand Teton National Park and to obtain comparative data to that obtained by Swenson from Yellowstone National Park.
