One of the pictures shows one of the birds carrying a twig back to the tree. It seems to me that they plan to build a nest there. This is why I was hesitant to report this sighting.
This is the same tree that has been reported on before. It has a flat top and it's right in the parking lot. I took Bailey off 101 and drove into the north entrance and saw one right away. Approaching from the south on Monterey doesn't give as good a view.
I kept my distance and took a few shots out through my sunroof, but these two didn't seem to mind me being there, so I parked and walked around.
