Pictures Set-up
#1 First Screenshot is called "Pictures Set-up". It showes your sky and your bird picture set up to move. This was done by going to top of PS page and going Window>Arrange>Cascade Vertically and then again to Window>Arrange>Match zoom and location. (you can see that I have picked vertically tiled and that the zoom % is the same) It also shows you the move tool and that the sky picture is active (it was activated by clicking on it).
