The behavior of the eagles suggests that they are now entering the egg-laying phase, which may take 3-5 days, as up to three eggs may be deposited. They are especially sensitive to disturbance during this time, so be very cautious when observing the nest.
Looking at my photos of the nest this morning, I fear that the right side may have had some loss of nesting materials, maybe after the big winds we had yesterday. I put a comparison of the nest with a photo from a month ago in my FLICKR album <http://www.flickr.com/photos/rosyfinch/>. Not sure, but it does suggest some damage. This morning I noted a good-sized stick fall from that area of the nest.
