During a June 2010 evening drive through Grand Teton National Park my husband and I came across a fantastic photographic opportunity - an interaction of two animals: a pronghorn (antelope) and a coyote.

                The pronghorn (Antilocapra americana) first appeared along the road sporadically trotting through the knee-high sagebrush and evergreens. Frequently stopping to rub her head against nearby vegetation, she kept a cautious eye on her surroundings.  As I took pictures of her, we were told that the pronghorn had just been down the road chasing a coyote (Canis latrans).  We then understood why she was staying in the area for so long.  We only had to wait a few minutes before the coyote appeared and the chase continued.  Off and on the pronghorn would rush the coyote and the coyote would take off with the pronghorn on its tail.  The pronghorn would stop usually after a short chase trying to get rid of the coyote, but the coyote continued to come back to the area.  They would rest for a few minutes, with the pronghorn scratching her head or neck on sagebrush, and then the chase would resume.  It continued until the coyote slinked under some trees to rest.  The doe wandered around rubbing her head and neck some more and waited to see if the coyote would venture out.  We waited, too, but the coyote remained there, occasionally poking its head out, until we had to leave.
