I was over between 11:30 and 1:45 yesterday. Buzz was not seen at all. Ruby spent about 10 minutes in the nest during that period, at 12:15 and 1:00 p.m. At the latter she fed the kids something briefly.
She spent a fair amount of time on the railings, but was relatively calm. Occasionally she hopped up and down a railing. She hit the south wall of the atrium once. Several times she flew around to the south side of the building, landing in the tree and attacking the window at least once. When she did that, she also called loudly as she flew a very short distance between the tree and the glass. I tried to run over each time she went there, but she spent about 10 minutes in the trees over four intervals, plus several minutes in the trees on the SE corner of the building after feinting at her image in the window. The kids got up once to stretch and turn around and void, and I had a few brief moments of all three chicks sitting together in the front of the nest. Most of the time they were just hunkered down, with two of the kids standing up, helicoptering, separately about ten minutes apart. Ruby crashed only twice that I saw, but was still fixated on her reflection despite low, dark clouds and intermittent light drizzle.
