Berkley Lake, Denver, CO
I noticed the pelicans swimming with the cormorants, then a flurry of wings and I didn't realize till I got home and looked at the images that the pelican was trying to take the fish from the cormorant. The next frame had the cormorant's entire head, with the fish, in the pelican's mouth.
