摘要

Data were collected on eagles trapped from winter 1989-90 through winter 1996-97. Although we concentrated our trapping efforts primarily in the Lemhi and Pahsimeroi River Valleys, we also trapped birds in the Birch Creek Valley during winter 1996-97 because of historical accounts of lead contamination in that area. In addition, we collected a few blood samples from injured eagles that were turned in to the Idaho Department of Fish and Game during the course of the study.
