This was the first time I actually saw a bald eagle alight on his nest and disappear into it.  I assume that (??? was is ???) what it was.  It was definitely a big bird.  The nest can be seen on top of a tree on a cliff adjacent to the highway.  The foliage will hide the nest later on.  The trees were still bare.  When I passed the nest, I noted how close it was to the gas station and restaurant and on the way home I spotted the nest for the first time across the highway.
