A Winter Roadside Survey Of Hawks In Eastern Nemaha County, Nebraska, Steve Shupe, Robert Collins

Nebraska Bird Review

During the winters of 1980-81 and 1981-82 roadside surveys of hawks were conducted on 76 square miles (196.8 square kilometers) of Nemaha County, Nebraska. Forty surveys were conducted each winter to acquire baseline data on distribution and populations. Ten species were observed, with the Red-tailed Hawk (49.7%) and the American Kestrel (21.5%) comprising more than 70%of all sightings. Population estimates for each species were determined by using square mile extrapolation and the bounded count method. Intervals of confidence were calculated in an attempt to determine upper and lower winter population limits.
