Baby American Robins about to fledge and leave the nest.
This photo was taken of robins in a nest over our front door. They were just about to leave the nest. The next day they were gone. We spied one of them in the middle of our driveway, then a parent robin came and fed it then it followed the parent into the woods to safer place as it could only fly a very short distance. In several days it will develop better flying skills.
So many times fledglings like this are scooped up by well-meaning people, convinced the fledgling has been adandoned. What a tragedy. If only they knew how to back up and observe from a distance, keep kids and cats indoors, and let the parents care for the fledgling and lead it to cover.
By the way, if you ever do find a truly abandoned fledgling or nestling, (confirmed by observing it for quite a while to be sure no parent is involved), you should know it is not legal for you to keep and raise a native bird. Bring the fledgling to a licensed bird rehabilitator.

With birds that nest in bird houses, such as bluebirds and Tree Swallows, the fledglings from the get go are better flyers than the young of birds who nest in open cups. Tree Swallows fly very well when they leave the box and are hardly fed at all by the parents, as they can catch food on their own. Bluebirds can fly somewhat when they leave the next box, usually enough to make it to the safety of trees. They are then fed for several weeks by the parents.
