Eagle nest---gone

A while back I showed you pictures of several Eagle nests not far from my home. I thought I would go check them out and I was shocked to find one totally gone. Well the tree was still standing but the nest is gone. It is in a wild life viewing area so I am going to call the Fish and Game people and see if they know what happened. We have had a few days of high winds but that nest has withstood all kinds of weather. I'll let you know what happens.
Here are the eagles and their nest taken not too long ago. MB
