In this cold, clear weather, birds are busy looking for enough fuel to get them through the days (and nights). Down low in the blackberries are Ruby-crowned Kinglets, picking arthropods and their eggs
as noisy flocks of American Robins clear mountain ash and other trees of berries.
European Starlings are flocking, looking for a chicken coop in which to hide.
And the top of the food chain is getting plumper. This Cooper's Hawk was unusually calm as I stood near, snapping shots.
She even casually scratched an itch. I wonder if they ever hurt themselves doing that. The relatively thick leg is one reason I think it's a Cooper's and not a Sharp-shinned Hawk. Other features suggesting COHA were relatively large size, tail shape (rounded) and shape of the head. This site provides helpful detail.
