Tom Mitchell reported that he observed the nest between 7:30 and 8:30 AM on Saturday DEC 1, and one adult eagle was sitting low in the nest the entire time.
I think it is safe to say that egg laying has begun. This may cover a period of 3-5 days, during which the female will occupy the nest just about all the time. After that we may see the pair exchange incubation duties, so keep a sharp eye out
