A downfall to so many windows on the backside of the Burrow is that the birds sometimes see the reflection of the woods. Usually they gently bump into my windows. Occasionally, when the hawk is out hunting, the gentle bump is a very loud THUD and a mark can be seen. Look at the upper left window below.
Here's a close up of that window pane.
It's usually the Mourning Doves the hawk hunts. Such a sweet bird. I am sorry to see their loss when it happens, but I respect the circle of life and am in awe at the hawk and the role they play in our world.This lucky dove just stunned himself. He sat by our backdoor for a few hours and then flew to the safety of a nearby tree. His foe had been scared off by the teenage girl in our household who cannot accept the circle of life when she's around. I also think my teen was hoping she'd have a new "pet" to nurse back to health. She is a compassionate soul.
