A comparative study of the breeding bird population of Shenandoah Mountains, Virginia

WHILE working on habitat studies of the Ruffed Grouse (Bonasa umbellus) in the George Washington National Forest during the late spring and early summer of 1941, the author found it possible to carry out a supplemental study on the relative abundance of the breeding birds of the area. Since considerable time was spent in traversing certain sections of the forest in search of Ruffed Grouse broods, an unusual opportunity was afforded to make a general comparative census of the species of birds found therein.
