First, as it's dying from weakness, shock, tetnus, or from ingesting some noxious plant, the eagles, hawks, crows, and vultures will pluck out the eyeballs. Next, the eagles will start surgically removing strips of flesh from the hind quaters, shoulders and back. This offers the best meat while the animal is still alive and tasty. In cool weather this can go on for a week before actual death occurs.
Next, after death, the eagles and hawks leave. They only prefer fresh prarie sushi. Now come the coyotes, foxes, vultures, and badgers. First thing they go for are the entrails(innerds and intestines). And yes, they remove them from the back end first. It's like pulling out rope. You keep on pulling for hours. Every now and then, a bladder, stomach, liver or such accompanies the intestines. In the summer , this ends the party, since the meat is pretty foul by this point. It's left for the rats, maggots, and insects. The hair or fur will make nice nesting material for every bird, rabbit, or vermin for a mile around. In the winter, the coyotes and wolves will dine on the carcass for months between good fresh kills.
It's esay to conclude that anyone stumbling on natures buffet party might confuse it for some strange animal mutilation, especially around the time it's been surgically skinned in strips and either barely alive or just dead with half it's intestines pulled out in what might look like an anal probe gone Manson.
I have great respect for eagles, but I did not know that they could cut off cow parts with surgical precision.
How would you explain the cow being completely drained of blood?
