Abstract
This study was conducted in the alpine regions of the Beartooth Plateau on the border of Wyoming and Montana during the summers of 1961 to 1964 and for shorter periods in the summers of 1958 to 1960. A general description of the geology and topography of the plateau is given. Six vegetation stand types were recognized, and the location, dominant plants, and their importance to the avifauna were described. Sixty-one spp. of birds were observed, and the status of each is described.
