I met Alec after the peregrines started nesting on the Cathedral of Learning. In the early years of the nest he used to come to the bandings. He loved the peregrines too and told me this story:

When many of the rooms in Cathedral of Learning did not have air conditioning (before the remodeling at the Honors College) he was conducting a seminar with a few students around a table on an upper floor of the CL. It was hot and the window was open. They heard something at the window and turned to see a peregrine on the sill. Everyone froze in awe. The peregrine slowly looked at the entire scene, then turned and flew away. You can imagine the impression this made on everyone in the room.

Wish I’d been there!
