Pronghorn antelope on Seedskadee National Wildlife Refuge. Pronghorn rely on their excellent eyesight to detect danger. They have a field of view that is 320 degrees or more, allowing them to see in front and to the sides, and also behind. The pronghorn doe on the left appears to be looking at us while she is facing completely away. Photo by Tom Koerner/USFWS. Posted on Flickr by the US Department of the Interior, 12/24/16.
