"Bats have sex beneath #Ravens Jeremy Butler vs #Lions -- They were escorted safely from the field. #batsex," Ferron tweeted, along with the version of the photo clearly showing the copulating animals. The photographer tweeted the bats, which he compared to "Pokemon characters" in appearance, gave "a whole new meaning to 'field of play.'"
