The only time I have been stung by a bee is riding and through shorts. I have also heard reports of rattlesnakes on some of the trails and get this- a bobcat! At DH's last mountain bike race they had one running on the trail. DH scared a wild turkey at the same trail. I don't know of anyone bit by a rattler but they scare me. We also have to watch for white tail deer, I have heard one report of someone hitting one they dart across the roads especially during rutting season. Our birds seem a bit mellower than yours thankfully.

I did once see a hawk drop out of the sky and grab a snake in a field while I was riding on the road. It was impressive to watch him fly with the 3-4 foot snake.

Oh we do have to be careful of cattle, they startle easy and in some spots there are open range ranches so that means cattle in the road! Someone told me they hit a bunny on a trail. The rider wasn't injured, she wasn't sure about the bunny though.
