I'm guessing a White-throated Sparrow, although I'm not very adept at identification. I was never trained to see the slight variations. I know people who can ID by a call or a brief view, I must say I very much do not discriminate among birds, they're big, little, brown with black or white, they whistle or chirp, they have feathers, and they give me much pleasure watching their antics. For that I will feed and care for them and be their friend.
