After Bob left, Karl arrived to help watch. He told that the parents had been spotted Monday night sitting on a building that is a few blocks south of the Temple grounds, called One Utah Center. There was confirmation that while they were spotted there, the two kids were flying around near the Church Office Building. I determined to visit One Utah Center soon so I could try to get some photos of the adults. Karl also said that kids could be seen flying south, maybe to that building, then returning very soon after (also on Monday night).
A few other watchers arrived and very soon after there was a fly in by both adults, a meal handoff and a lot of sqwauking (presumably because Lexi didn't want to share her meal with Early and was warning him off). There has been growning suspicion that Lexi, who was thought to be a female while she was still in the nest, (then was identified as a male upon tagging) is actually a female after all. I was told that she/he is displaying plumage that is more identifiable as a female, like the dark bars showing in the second picture below.
I have a whole string of flying pictures that I will post later today. They are from a last week but they are so great, I just have to put more of them up. I am on duty tonight as well, so there should be more pictures tomorrow.
