Falcon ID - BC Canada (1 Viewer)

[benoitjh]

Hello, looking for confirmation on this bird, seen today in S. Central BC around farmland/pond.
I thought the head looked good for peregrine but I am thrown off by the distinct shading under the wings perhaps like a Prairie Falcon. Common to also see Merlin and Kestrel in this area.
Thanks for assistance

I don't think a Prairie Falcon would show such a thick moustache.

Peregrine for me, too. I'm not seeing the truly dark/black underwings of Prairie, just a medium shade of uniform brown.
