In parts of the plains, coyotes had to compete with one of the most formidable scavengers — the Great Bear. Once known as Ursus horribilis, it's now known as Ursus arctos. This includes the brown bear of Europe and Asia, the Kodiak bear of the north Pacific coast, and the grizzly bear of North America's mountains and plains. The great bear eats mostly vegetation, including a good bit of grass. But its simple stomach can't get much of the good out of grass, though it does better on fruit and roots. Its closest relative is the polar bear, which is carnivorous. Grizzlies are enthusiastic carnivores, but when it comes to taking on the large hoofed animals on the plains, they are not very efficient. The great bear's avid appetite for meat may explain part of the male bear's enthusiasm for killing cubs.
