Info from Licensor: "There is a local bat colony not far from where I live. Just before sunset every night, they take off and fly south in a direct path over our home, presumably for feeding. There are literally thousands of bats. This video only goes for 1 minute, but the bats continue to emerge from the trees for 10-15 minutes each night. It's an amazing sight!"
