White-throated Sparrows (Zonotrichia albicollis) always remind me of Santa Claus because of their white “beards.” The effect was magnified on a recent frigid morning at Occoquan Bay National Wildlife Refuge, when a White-throated Sparrow had fluffed up its feathers to retain heat and looked even chubbier than normal.

I love everything about this image.
