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.

It was a tufted titmouse!
