Confusion While Hunting

So you are at the famous Christmas Place Hunting Club up in a white oak tree waiting for a big old buck to come out and suddenly a large group of elephant-like animals come out of the thicket and come over to your tree and start eating acorns right off the tree. They're blaring and huffing and grunting and making all kind of racket while they look you in the eye or poke you with their trunks and you realize that you need to make a decision. Are they Mammoths or are they Mastodons? See how confusing it is?
