During fall and winter, moose consume large quantities of willow, birch, and aspen twigs. In some areas, moose actually establish a “hedge” or browse line 6 to 8 ft (1.8 – 2.4 m) above the ground by clipping most of the terminal shoots of favored food species. Spring is the time of grazing as well as browsing. Moose eat a variety of foods, particularly sedges, equisetum (horsetail), pond weeds, and grasses. During summer, moose feed on vegetation in shallow ponds, forbs, and the leaves of birch, willow, and aspen.

Only bull moose have antlers. The largest moose antlers in North America come from Alaska, the Yukon Territory, and the Northwest Territories of Canada. Trophy class bulls are found throughout Alaska, but the largest come from the western portion of the state. Moose occasionally produce trophy-size antlers when they are 6 or 7 years old, with the largest antlers grown at approximately 10 – 12 years of age. In the wild, moose rarely live more than 16 years.
