Your post brought a past sighting to mind.
A few years back I visited the CWB in Winnepeg ( currently a news topic ) , and my contact was also a birder . He showed me a peregrine nest situated on the roof of a bank - being monitored through a camera with the monitor set up in the teller area of the bank . The falcon was not at the nest , however, I did spot it couple of times flying in the area.
