Maybe you could get one of those blow up owls that they put in barns to discourage little birds from coming in...strap it to your back. Maybe it would help with the birds.
I was attacked by ground wasps once while mowing a field, and had a major incident with hornets that thad taken up residence in a cross country log I was using while teaching a jumping lesson (with horses, not bikes)...they were MAD, MAD, MAD and the horses knew it, but have never been stung while riding the road bike.
Everything bites me on the mountain bike. Mosquitos, wasps, bees, spiders, and ticks. I am like a magnet. I have avoided (narrowly) snakes and the kamikazee squirrels that reside in the park here. I keep waiting for one to jump on my head and latch on to my ear or nose. But so far no takers.
