Example of the 2 different crossing behaviors exhibited by pronghorn when crossing a fence (A) and a road (B). When crossing under a fence, a pronghorn must crawl on its elbows to get under the bottom wire of the fence (A). Note the hair loss and scaring on the neck and back of the animal depicted in (A) as a result of crawling under fences. When crossing a road, a pronghorn can walk or run across depending on the presence of a vehicle (B). Note the flared white rump patch on the animal depicted in (B), which is an anti-predatory alarm sign used by pronghorn. Panel C depicts a pronghorn crossing a road that is fenced on one side. Panel D depicts a group of pronghorn crossing a road with two fences where both the fence and road crossing behaviors are employed. Also note the spatial distance covered to successfully cross each linear feature. (Photos: A—Alberta Conservation Association; B—P. F. Jones, Alberta Conservation Association, C—A. F.
