Mature bald eagles have a white head, neck, and tail, and a dark-brown body. They are 30 to 43 inches long, with wingspans of 80 to 96 inches. Chiefly fish-eaters, they have powerful bills and talons, and are sometimes seen stealing fish from other raptors. Gray, or timber, wolves are rarely seen, although hikers often find their scat and four-toed tracks, or hear their haunting yips and howls. The gregarious animals live in packs, mate for life, and hunt caribou, deer, and moose.
Arctic foxes inhabit tundra or icy mountain and sea regions.
White in winter, grayish or brown in summer, they attain a length of 20 to 24 inches. Their diet consists of small animals and vegetation.
