Mystery Bird

Do you know what this is? I don't. It has olive shoulders, an olive white back, and a white rump with a yellow spot. It's about the size of a Goldfinch:

Notice the white wing bars, and the yellow neck. What are you, bird?!? The House Finch which shouldn't be there.

This is another picture from the side:

The mystery bird strikes back

It's not a Goldfinch though; the head, rump and wing bar's pattern do not match. It also looked as though it had a crest at one point, but I think that was just hurricane/superstorm Sandy's wind. Please comment if you think you know what it is. Thanks!
