My son and I were driving on our way to Banff one morning. It was still early dawn when we came across a herd of approximately 30 Pronghorn feeding in a field near Kindersley SK . Although you may not guess so from their somewhat shorter legs and stubby body, Pronghorn are the fastest animals in North America, capable of reaching speeds of almost 100 km/hr (60 mph). They are a different species from antelope which are found in the United States. Unlike deer who may stay more in the trees, pronghorn prefer to roam in areas where they have the high ground and can run off at the first sight of danger. It therefore makes sense that I had found these animals on a higher ridge leading to an open field. Also unlike deer, they don't like to jump over barbed wire or other fences and instead prefer to duck underneath them when possible. (cited from National Geographic Nov 2010 edition).
