Wow, the peregrines have really been surprising this year. I’ve posted about the fights Sean and I witnessed when we were tracking the river birds. The first fight took place over Prudential Two and the second, and most recent, in the skies above Michigan Avenue and Wacker Drive. Between those two battles, the nest at Mag Mile failed. When I reported the second fight to Mary, I wondered out-loud whether it was possible that the Mag Mile birds were looking to renest and had wandered into the river birds territory in their quest to find a new site. Mary admitted she’d wondered the same thing.
Cut to a week or so later. Mary called me to say she’d received and email from a man named David. Turns out, he reads this blog! Also, turns out he works in the London Guarantee building, which is a site the river birds have used for nesting from time to time. David and his co-workers reported that a pair of peregrines had been hanging around right outside the windows of their office. Apparently, they’d caused quite the stir and had become, to some extent, celebrities/mascots for the inhabitants of the office. Could this be our wandering river pair?
