I just had two Peregrine Falcons (Falco peregrinus) scream by the apartment building at eye (fifth floor eye) level. One pulled up and did a little “wing over” before peeling off in another direction.
This is the second time that I’ve seen Peregrines in the last week or so. I know that they live over on the CIBC building at Yonge & Bloor, but I hadn’t seen them outside my window.
