In North America bears have branched out into numerous species, and here they have attained their greatest development. South America has, perhaps, only one small species, and Africa only one. Europe and Asia combined are accredited with having eight species. The grizzly is distributed over the western half of North America, from northern Alaska far down into Mexico. His home is more generally in the mountains. He is also found in the barren lands of Canada, in the Bad Lands of the Upper Missouri, and in the western margin of the Great Plains. On a number of the wilderness islands of the Alaskan and Northwest Coast, where he is of unusually large size, he forms a numerous population. The similarity of the mental processes and the customs of the various species of Alaskan bears has been remarked upon by many people. Mr. Charles Sheldon, the hunter-scientist, says:-- "Nothing is more striking than the general similarity in nature, actions, appearance, and habits of both the brown bears of the humid coast region of Alaska and the grizzlies of the dry interior. The several species of both the coast and inland bears differ more or less widely in size, anatomy, color, and claws, but no one can observe them in their natural habitats without realizing that all have descended from a common ancestor." The little that I have seen of the polar bear suggests to me that he may be related to the grizzly. It is interesting that the coats of the polar bear are uniformly white, while those of the grizzly are of assorted colors. The grizzly is scattered over a vast and varied range, feeds on a variety of food, and is divided into numerous species and subspecies, but he ever runs true to character, everywhere is one hundred per cent grizzly. The chief points of dissimilarity in the different species are the shape of the skull and the character of the teeth. Rarely is there any difference apparent in the living animals; the classification is determined chiefly from the teeth and the formation of the skull. Color is no clue to the species. Color may vary as much in one species, or even in one litter of cubs, as in different species widely separated as to locality. Assemble a number of grizzlies representing each of the many species and subspecies, and there will be a bewildering array of fur coats, perhaps no two alike. However, as I have said, the grizzly's characteristics are ever the same, no matter what the color of his coat or where he lives. Wherever you see a grizzly,--on the glaciers of Alaska, on the desert sands of Mexico, or fishing in the Columbia,--he seems as much the same old acquaintance as the bluebird who comes each spring.
