Road kill aside, shouldn’t we come across more creature corpses more often?

There are SO many birds and rodents alone. We should come across their dead on at least a weekly basis.

Have you ever seen a dead squirrel that wasn’t smashed into the asphalt? What about a pigeon that gave up the ghost without a windshield? How about a deer taking it’s dirtnap in the middle of a trail?

I surmise the following:

Wildlife doesn’t die unless by violence or disease. Which make critters undead or like the Eldar. Orrrrr they eat their dead.
