The bull moose produce large palmate antlers which are shed annually. Although cow moose do not have antlers, both bulls and cows do have a bell which is a growth of skin and hair that hangs down from the throat. Calves are born in the spring and remain with the cow for a year. Cow moose will aggressively protect their young from any perceived threat. Moose browse on twigs and leaves.
Willows are an important food source, and moose also feed on submerged aquatic plants.
Moose are dark in color ranging from brown to black. The moose also has long legs which are an adaptation to the thick marshes where it feeds and to a habitat that is covered by deep snow much of the year. The moose is normally a reclusive animal. You are most likely to see one in the streams, marshes, and willow thickets along the road between Mammoth Hot Springs and Norris. Occasionally, they can be observed feeding or resting while partially submerged in water.
