A robin built two nests next to each other up under our covered patio. Today a nestling fell out of the one she laid eggs in. I put it back up in the second nest because the original was coming apart with no type of bowl to keep the nestling secure (no other nestlings up there or on the ground and I'm not sure how long it had been on the ground). Mama bird was watching me from a distance but she hasn't came back to the nest yet (been close to an hour). Will she check the nest again for her baby? The nestling was alive and stretching its neck for food when I was putting it back.
