Says who?
Animals, in general, have high accident rates.
They simply are not generally recorded.
When animals are injured in the wild, they tend to be killed and eaten fairly quickly.
I saw something on TV where a herd of reindeer were killed by a lightning strike. I saw a lightning strike on a mountain across my canyon one night. It was awesome. It started a brushfire and by the time the Forrest service fire department got there the skies opened up and put it out. It’s the dry lightning that is the problem.
Actually, it was a joke...
