A blue bird. With a short tail. A moderately short wing. And a thickish bill. Not much else matches that description than a male Indigo Bunting -- and one that has attained full adult plumage, with a complete set of bright blue edgings on the flight feathers and wing coverts.
The classic confusion species is Blue Grosbeak, another member of the genus Passerina. But especially in a view like this, we'd see the shorter, darker, white-tipped tail of a Blue Grosbeak, the fatter body, the extensively rusty wings, the blacker face, and the more cardinal-like bill of that larger species. In poor light or at a distance, either species can appear simply blackish, but even then the shorter tail, bulkier body, and heavier bill of Blue Grosbeak should distinguish it readily from the slighter and more gracile Indigo Bunting.

Well, after all the agonizing I did the other day, I should certainly know that beak by now. :-)
The male's plumage makes the answer a little easier this time: indigo bunting.
This is a male Indigo Bunting. It does not have the brown on thw wings asociated with a male blue grossbeak, and its beak looks smaller than that of a blue grossbeak.

Not only is it a male Indigo Bunting (INBU), it is an after-second-year (ASY) male INBU, based on the black (not brown) primaries and the fully blue (not brownish black) primary coverts. Additionally, these birds usually don't get that nearly purple color on the head until after the second year.
The first bird I ever banded was an ASY INBU. It looked a lot like this one. Nice bird!
That is the Blue Bird of Happiness!
