Grizzly Bears eat Deer
One of the most predators of deer that eat deer is the grizzly bear, also called the North American brown bear. Although it may not move as quickly as the feline predators below, it is just as large and lethal. After all, the typical male grizzly bear is between 180 and 360 kilos in weight and is about 6.5 feet tall.
The grizzly bear is a meat-eating carnivore, although it usually eats both plants and animals, making it an omnivore. It favors large creatures, including elk, moose, caribou, mule deer, and white-tailed deer, as well as several deer species. Some deer species, like the elk and the moose, are dangerous prey due to their size. Because of this, the grizzly bear begins stalking them. A frail adult or even a vulnerable calf will come under attack if all else fails. The declining population of elks in Yellowstone National Park is attributed to the grizzly bear's preference for young animals.
