Elk mother and calf, Great Smoky Mountains National Park

Elk mother and her calf. Cow elk are very protective of their calves.

Elk dwell in open forest and forest-edge habitats, grazing on grasses and sedges and browsing higher-growing plants, leaves, twigs and bark. Male elk have large, blood- and nerve-filled antlers, which they routinely shed each year as the weather warms. Males also engage in ritualized mating behaviors during the mating season, including posturing to attract females, antler-wrestling (sparring), and bugling, a loud series of throaty whistles, bellows, screams, and other vocalizations that establish dominance over other males and aim to attract females.
