Chilly White-throated Sparrow

At least I am thinking it's a female white-throated sparrow. Positve ID help would be appreciated. I have a mental thing with sparrows and shorebirds.
Spotted this little bundle of feathers under the bushes at the edge of the birdfeeder. She has two legs and feet, but she was trying to keep one warm.

Very nice detailed shot of what I believe is a tan morph White-throated Sparrow.

Nice shot. I have one wintering over in my yard this year. I don't think you can tell any differences in sexes.

Beautiful shot, looks very much like the female of a pair of white-throated sparrows I have in my yard.
