Morning in Tucson

I popped out for some emergency groceries before breakfast; it's a bright, cold morning, with frost clinging to shady slopes here and there. Arriving home again, I happened to glance up and see a small hawk perched atop a utility pole, sharp against the sky. I don't think it was a redtail, which is what we usually get around here in the winter; it was too small and too grey, but it was definitely a raptor and not a pigeon.
