Ecology of the Mountain Sheep

Abstract

Most of the field data herein presented were obtained by the writer as an employee of the Wyoming Fish and Game Commission while studying the decimating factors affecting the Rocky Mountain bighorn sheep (Ovis canadensis), in the Gros Ventre area of northwestern Wyoming. Prior to the initiation of the actual study, Dr. John W. Scott, Executive Secretary of the Wyoming Fish and Game Commission, gave the author permission to use such ecological data as herein contained. The field study extended from November, 1938 to October, 1939 during which bands of sheep were kept under almost daily observation.
