It was 25°F when I drove to work along Coleman Valley Road this morning. I stopped briefly for a few frost photos.

I wasn't the only one surveying (and puffed up in) the chilly morning scene:
Varied Thrush (Ixoreus naevius). This species often blends in with its surroundings, but in this light it was notable how the oranges and blues stood out against the grays and greens.
Hermit Thrush (Catharus guttatus). It landed in a tree right above me and peered down with its large eye. A magical view!
