Zonotrichia leucophrys

A flock of House Sparrows live in a juniper bush in our front yard, and regularly make noisy forays into the back yard for food and drink. Once every few days, I see this (single) White-Crowned Sparrow mixed in with them. This is admittedly not the world's greatest photo of this bird (a foreground obstruction blurs the lower part of the image), but he rarely gets to a place where I can get a clear photo, and this is the first chance I have had to post a picture of one this year. He's foraging in yesterday's snow for some seed, along with the other sparrows and Juncos.
