Leaving the nest

As I was walking out into the garage this morning I saw a bird flying from the nest.  At first I thought it was one of the parents but then I noticed that it wasn't flying real good.  It flew over to the window and then flopped down.  I went over and it was on the ground and seemed to be okay.  It had plenty of places to hide so I wasn't worried about the pups getting to it.  I am sure the parents will come back when I am not in there and teach it to fly.  If the parents are there, they will protect the little ones.
