I awoke to the sounds of bats and birds chirping in my building today. Bats used to live in swarms at my grandmothers house, so I know thier sounds quite well. As a child, my grandmother and I would take graham crackers and milk and go outside after dark to sit on her front porch. we would do this all in hopes a bat would fly close enough to the street lamp and then we could get a good look at one.
Today it sounded as if the bats and birds were singing to one another.
