Pat Maxwell found this small bird, a Brown Creeper, stunned from his collision with her window.
The bird rested while, as Pat put it, his brain unscrambled. She said it then pooped in her hand and flew off! Brown Creepers are woodland birds. They spiral up the tallest tree they can find, looking for insects and spiders. The male's song is very high - it's easy to miss it. If you'd like to hear their call, here is the link to the Cornell Lab of Ornithology: https://www.allaboutbirds.org/guide/Brown_Creeper/sounds
Thanks to Pat for allowing me to share her photo with you here.
