I took a drive to the Lamar Valley today and came upon coyotes on an elk carcass. There were anywhere from 6 to 8 coyotes around the kill. It was an amazing experience watching their behavior. There was definitely a pecking order. When the dominant coyote would get full and move off to rest, others would move in. I spent over 4 hours out in the cold photographing and enjoying the event. This guy was letting an approaching coyote know that he was not welcome.

A coyote bares his teeth as he approaches the elk carcass.

When they were away from the kill, they exhibited no signs of aggression.

This guy goes on alert at the approach of 3 more coyotes.
