I'm not running around like henny penny. In summer we have loads of bats flying around the street light catching bugs at night. But, I have always read you don't ever approach a bat laying on the ground,. I wouldn't try to pick up a raccoon or opposum or fox, that didn't move away at my approach. I did want to help a hummingbird that once knocked himself out on our picture window. I saw he had a little blood around his beak(?). By the time I got outside he was gone.
They have had several reported cases of rabies in bats in suburban areas close to us - our area has aloads of forest preserve area and all the accompanying critters.
