From Langis Sirois, April 3, 2016:
As I was driving towards the Data Centre at 9h45 yesterday morning April 2, I saw a bird flight toward the West end of the building. When I arrived in the parking lot South of the building I saw a Peregrine Falcon perched on the ledge in front of the former nest site ; by the size, I thought it was a male. I heard calling and saw that bird fly to the West end corner – it had a small prey in its claws ; it was thereafter only partly in view. After a few minutes I saw a bird fly toward the East and land at the East corner of the building – an adult which, by its size, looked like the female. I heard calls again and saw that bird fly to the ledge in front of the nest and go to the nest after a few moments.
