The elk or wapiti (Cervus canadensis) is one of the largest species within the Cervidae or deer family in the world, and one of the largest land mammals in North America and eastern Asia. This animal should not be confused with the larger moose (Alces alces), to which the name "elk" applies in the British Isles and Eurasia. Apart from the moose, the only other member of the deer family to rival the elk in size is the south Asian sambar (Rusa unicolor).
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 which establishes dominance over other males and attracts females.
