If you can get close enough to a carcass, you'll see there is a pecking order with the wildlife that's trying to get a meal, which can result in lot of squabbling. The big and the powerful species will dominate most of the times. Even within one specie, there can be an order to follow, from the oldest to the youngest or strongest to the weakest. With the carcass in the picture, first came the coyotes, followed by eagles, right behind were the ravens and magpies when this picture was taken.
Until next moment,
