Looks good for a Taiga bird (F. columbarius columbarius)
Edit: I don't have Wheeler to check, but the bird doesn't look light enough for a Prairie, imo. I believe columbarius should be the expected subspecies in the east, even during winter.

That's what I thought too. I saw my first merlin yesterday at Peter's Canyon. I wasn't looking for it (had given up in the other location and didn't expect to see it there). I ask because the merlin I saw appears very much like this one, Taiga.

A west coast birder might be able to speak to this better, but ebird shows Taiga as the most frequently reported species in SoCal during the winter. The Black subspecies is usually resident further north and Prairies seem to be considerably less common.

I just checked, and the areas around me, which is where I found the merlin, do show that.
I have a question: any idea of the evolutionary advantage to a female being larger than a male? I read this (Wheeler/Clark) is the case in merlins, and I am just curious why.
