She seemed to shift around a lot, as if something under her was making her uncomfortable. We finally decided that was all we were going to see. So we took the camera off the scope, took the scope down, and started to walk away. We were 20 yards away when we heard the call of an incoming hawk and rushed back. From what we saw, we think it was a food drop off. For awhile, the hawk left in the nest kept looking down, as if watching the kids eat. Then she clearly began eating, tearing pieces off. Periodically she would give us the "hawk eye". I managed to get this pretty good picture of her before she settled down and all we could see was her tail again.
