They usually eat grass, but they also eat twigs. A long time ago elk were found all over North America. Hunters killed many elk. For a while there were only a few left in the Rocky Mountains. Elk are now mainly found in western North America.
Elk move in herds.
In the spring and summer they are in the high mountains. In the fall they move down the mountains. The males and female are usually separate. They travel together in the winter. Bull elk can move silently through forests at speeds up to 35 mph.
