I saw this poor little thing seemingly struggling on the ground last night by my house. It doesn't look like a fledgling, but maybe I'm wrong. Kept it in a ventilated shoe box with a towel overnight and let it out just now. I feel bad leaving it there in this state. Do/can I do anything for it? No signs of blood or missing feathers. Wings seem ok. Metro Detroit area.
