This eastern screech was so focused on our bats, that he allowed us to approach to within 6 feet before finally flying off!  The rehabilitating bats are working on their flight skills and for that reason, they attract even more attention from local owls.
Our Mexican free-tail Bernie has a permanently injured wrist but was roaming the flight cage last night.  But for the netting, he would have been scooped up in an instant by this owl.
