Moose live on the margins of lakes, muskegs and streams of the boreal forest, on the rocky, wooded hillsides of the western mountain ranges and now even northward through the transition forest that extends to the open tundra. Moose can also travel through practically any terrain. Their long, stilt-like legs make it easy for them to travel over deadfall trees and deep snow. A moose's antlers are pale in colour, sometimes almost white. They are used for fighting in the hunting season. It is in the late summer and autumn that a mature bull carries its rack of antlers, which normally span between 120 and 150 centimetres.
