From Langis Sirois, April 2, 2016:
Yesterday, around 3:30PM there was a Peregrine falcon at the Data Centre on Heron Rd, it was sitting on a ledge on the South side at the West end. I saw it from Heron Rd and had no time to go closer, but I beleive it was a male.
This was the first time since late January that I saw a peregrine there. I had checked numerous times in recent weeks.
I will check again this morning and in the days to come.
