Absolutely Lesser Goldfinch. By the way, I don't know how much time you spent looking at warbler pics, but you would have saved yourself that effort by noting the bill shape: warblers have much thinner bills. Bill shape and size is often a good clue to point you in the right direction; bright colour patterns you'll likely remember without trying, but the bill really needs to be looked at (unless we're talking about a toucan or spoonbill etc). Just a friendly hint. -O-

Ok...so I believe Google helped me ID this as a zebra finch. Looks like it's native to Australia! Must be someone's escaped pet? Wonder how he's doing today? He's a long way from home here in NE FL.

Might be an Eastern Phoebe. Looks like it has the "Phoebe smudge" on the sides of its chest & a thin eye ring.

Whitelacey.......this is so funny! I looked out my kitchen window, and on the ground under my suet feeder was a bird that looked just like what you described. Very black head and back with white stripes on the wings, and very white chest and abdomen. Of course, just as I turned to get my camera, it flew off. I should have stayed and observed more instead! As it flew off, it had pretty obvious white wing stripes. My first inclination was a juvenile male towhee.....since we have lots of towhees around. I saw no brown. I'll keep my eye out and my camera close-by........but I immediately thought of you and wondered if, now, I will be driven crazy too. hahaha What caught my eye as it was flying up to a tree was the white on it's wings, which made me think of a red-headed woodpecker. I looked up juvenile redheaded woodpecker and some of the pics looked like it, except mostly in the pics, their heads were grayish. Oh well.....hopefully I'll see it again!
