When I started to watch the eagle cam, there was one eagle lying down with its head up. It looked around and twitched its wings a few times until putting its head down after about three minutes. When it put its head down, its wings moved to the side of its body exposing its white tail. This was the majority of the movement I saw. Towards the end of the 15 minutes, the eagle sat up at started to dart its head around with its beak open. Its wings moved more central again, covering its tail. It also started to breath heavier. That is all I observed during the 15 minutes.
