On Christmas Eve of 2012 I visited Fort Marcy Park in Santa Fe, New Mexico.  There I found a flock of maybe ten Western bluebirds.  The temperature was just above freezing and the birds were intent on getting water from a few trickles from runoff.  And I found a few eating berries from the cedar or juniper trees around the park.  All of these photos were of male bluebirds, but there were females in the flock.

The odd-man out is a male finch, presumably a House finch.
