The Omnivorous Opportunists

Animals such as Pandas are very picky eating only bamboo. And when humans destroyed bamboo forests their population crashed. They had no other food to fall back on. But many other animals have. They are all successful omnivores.

The Raccoon
With and extreme sense of touch these are very successful omnivores. When in a creek, they feel underwater and build an image of what there is. And they can distinguish the difference between Oysters and rocks. When they feel a crayfish which has pincers they quickly kill it by disarming it and then eating the soft underside.

Skunks
In caves for a few months skunks dwell in them. Bats poo and produce a strong ammonia smell and the ground is full of flesh eating beetles. But still skunks prefer this place. It's when young bats are born. These bats are flightless and the huge number of them causes some to lose gripping. The skunk uses its hearing and depends on bumping into them. But if the bats once again reaches the wall, its safe.

Grizzly Bears 
These animals consume at least 12 salmon a day. Salmon in this season of late summer migrate in great numbers of 1,000's together and an easy feast of fat. And a few months before hibernation they eat berries because it's berry season. They can consume up to 200,000 berries a day. This boosts their hope of hibernation survival for 4 months in the winter.
