Notes on the Birds of the Elk Mountain Region, Gunnison County, Colorado
Abstract
292 Warren, Birds of the Elk Mountain Region, Colo.[sae now be held of specific value, as no intermediate specimens are: forthcoming."It remained for M. Johan Beetz to point out the fact that there is an intermediate form between dresseri and borealis.Instead of this form.beinga new species, as M. Beetz suggests, it seems to me, however, that his important discovery shows that dressert intergrades with borealis, and that like borealis it should be classed as a subspecies of mollissima.If this view is accepted this Eider should be reduced from its specific station and be listed as Somateria mollissima dressert.A study of the breeding Eiders about Hamilton Inlet, the supposed dividing line between the ranges of borealis on the north and dresserii on the south, would be of interest.-C.W.
