People think nature is perfect and nothing ever goes wrong. NONSENSE! I have customers who complain when their horses trip. They attribute every human characteristic to animals except the ability to err.
The La Brea tar pits are filled with mistakes animals have made.
I remember finding a racoon that had crawled up inside a hollow tree and tried to get out through a knot hole catching its hips. It died there.
I frequently see dear leap fences and land on them. A deer lept into the neighbor’s pool where it died. I have seen bucks with their antlers locked and dying. I saw a deer that tried to leap a tall wrought iron gate it impaled itself on. I have frequently seen a number of different animals trapped in deep creek beds or ravines unable to get out. I have seen animals attempt to swim rivers that were too swift.
One of my favorite Gary Larson toons is a beautiful picture of a buck running through the woods leaping over a log about to catch his rack on a low hanging branch. He captioned it, “Seldom seen Nature scenes.” From my experience these events are far from seldom, though I am sure they are rare in a cartoonists drawing room.
We humans have police, fireman, etc. to rescue us when we do something stupid. Animals die from their mistakes.
