Booni thanks for the photos. Mum did take a beating. When I found out she had gone missing I went back to look at the videos of her, including the last day she was seen. From the time she was injured to the time she left, she was eating, flying and really looked very strong. On the last video she was in the nest by herself. There had been an influx of more eagles due to some sort of feeding frenzy going on in the water. What I remember is that she was looking strong, but nervous as other eagles flew overhead. Then she started jumping up and down in the nest and calling out, it seemed angrily. I still think she left because she was weakened by the fight where she was injured, felt intimidated by all of the aggressive eagles, and went off to follow the food as Booni said. I really hope we see her again in October.
