Tonight was bitter sweet. The park's resident Screech-Owl was back in a spot she has used more frequently in the fall. She looked great and I was happy to see her in good health. (Screech-owls generally switch between a few cavities to roost, and I haven't been able to find her alternative locations over the past few weeks.)
After fly out, she called almost immediately and continued to call for over an hour. When I left she was still calling. Now is the time she would normally be starting to brood, but without a mate she was just calling and calling.
