I visited the Cathedral twice on Saturday. In the late morning, and in the late afternoon. The nest is too high and too deep to see into, so we depend on the behavior changes of the parents as our clue that there are eyasses.
There were plenty of clues on Saturday, including food being taken into the nest, lots of feeding behavior, etc.
In the morning, when I arrived, no one was to be seen. Soon the adult male arrived on the Archangel.
In the afternoon, I return around 5:00 p.m.
