Picture taken from last year of the female
I am now almost certain the Peregrine Falcons are nesting on top of the Unum building in their usual nest box. I saw both of them for the first time in weeks, right at the ledge of the nest box; they were in the midst of a nest switch off, I believe. The falcon on the ledge would remain there for only a few seconds until it went inside the nest box, presumably to incubate eggs. On another note, I spoke to Emily and it doesn't appear that Fish & Wildlife will be making a visit to the nest site until banding is done this summer, so it looks as if there will be no egg count. I will post updates as I get more information.
Just thought I'd share!
