I found this Elk Fawn hiding not far from his nervous mother in the Lamar Valley of Yellowstone National Park in western Wyoming. Elk and other members of the deer family belong to a group of animals called ungulates, the Latin word for “hoof.” Members of the deer family must eat and watch for predators at the same time. Elk fulfill these double needs by gathering in herds. In a group, at least one animal is looking up while others are eating. Even the animals that are feeding are constantly twitching and turning their ears to listen for unusual or warning sounds. The young elk fawns must hide in the tall grass until they are strong enough to run and escape predators.
