Each evening, before dark, with just enough light to see my way around the garden, I go to shut the door on the chicken coop. I then walk around the house with the dogs. I generally see bats flying around summertime, but they do seem to be dive-bombing me more than usual and follow me closely as I go around the garden, right up until I go inside. It's not a problem as I love watching them twist and turn at amazing speed, it is hard to keep a track of them. But I wonder is there a reason, are they playful, fearful or what?
