Peregrine falcons have been nesting on a ledge high on the exterior of the Library Tower at the University of Calgary for almost a decade. They've returned each year, but failed to nest in 2004 and 2005. As I was heading for the bus with Evan after work yesterday, we heard one of the falcons screeching from a nearby poplar tree. Evan hadn't heard a bird that sounded like that before, so we got to have a nice talk about falcons while walking to the bus stop.
At least one falcon has returned this year. I'll keep my eyes open for its mate, and hopefully they make a nest again this year.
