I have baby birdies

Some tiny sparrows have managed to make a nest just behind a piece of siding that's under my bedroom window sill. All I hear every 5 minutes is tweet tweet tweet tweet tweet. At least they are more or less faint, so they are not an annoyance. They can just barely open their eyes, but for the most part keep them closed still.

The yellow in the pics are from the sides of their beaks, so seeing two yellow kind of lined up with black in between is the full beak, like in this pic.
