During the mating season in the autumn, the rams battle for dominance by crashing horns together until the weaker animal gives up. Horn tips are often broken during these battles. Bighorn sheep are frequently seen on Highway 16 east of Jasper and along the Icefields Parkway at Tangle Falls. Actually, they are not goats, but belong to a group of mountain antelopes. During the rut, fights between billies are rare, but when they do occur, they are vicious and involve goring with their sharp horns.
Goats are generalists and live on a wide variety of vegetation.
This allows them to survive year round at elevations above 2000 metres. There is no seasonal migration, but goats often trek to salt licks in the valleys. Overhunting and possibly disease wiped out all the native bison in this area by about the mid-1800s. Today there is only one bison living in Jasper. You can look for it in the Rocky River area of the park.
