Cartão Bull Elk Resting

"Bull Elk Resting" by Catherine Sherman. A bull elk rests while chewing its cud on a hillside in Estes Park, Colorado. On the back of the card, a bull elk bugles (calls) to his herd of about fifty female elk, who are following him on a hillside in Estes Park. The town of Estes Park is outside of Rocky Mountain National Park. The elk or wapiti (Cervus canadensis) is one of the largest species within the deer family, Cervidae, in the world, and one of the largest terrestrial mammals in North America and Northeast Asia. Elk range in forest and forest-edge habitat, feeding on grasses, plants, leaves, and bark. Male elk have large antlers which are shed each year. Males also engage in ritualized mating behaviors during the rut, including posturing, antler wrestling (sparring), and bugling, a loud series of vocalizations that establishes dominance over other males and attracts females.
