I shouldn't get all sentimental about a bird, especially a wild bird, but the San Jose City Hall peregrine falcons are birds we're all emotionally involved with. I've watched them grow up, very literally, on the nest webcam. So one of them apparently hit a building and died, Monday. Fiesty little Cielo, who chewed up the thumbs of the guy who banded her. I know that most young raptors don't survive their first year, but damn, I'd gotten to know this one. I was almost as upset over the news as I was over death of the 6th-grader who was struck by a car and killed, two blocks from the house, the other day.
