Daughter was laying on floor by sliding glass door and started exclaiming about shiny birds. I ran over to see what she was talking about and there was a large group of floating/shifting shiny objects not far from above our home. At first I thought they were birds; they looked like they had wings at first but the way they were shining and moving seemed wrong. Perhaps, a large group of foil balloons tied together or drones? They kept getting further away and they would shift around together quickly, change formation shape and become invisible at times. My husband and 3 year old were also watching. Barely captured part of it on video.
