Research video published by the Wyoming Migration Initiative on Wednesday (February 10) shows a group of 20 mule deer as they approach the obstacle and cross to the other side one by one, either by jumping over or walking under the fence, designed to allow wild animals to cross while keeping farm animals coralled.

The trail camera footage was taken by student Tanner Warder as part of University of Wyoming research. It captures the mule deer migrating from high elevation mountains after spending their summer in Hoback Basin or the Upper Green River Valley, Wyoming Migration Initiative told Reuters in an email.

About 4,000-5,000 mule deer use the migration corridor each year, with some travelling 150 miles (241 kilometre) to the desert from the mountains and have to cross 100 fences on their way.
