Crow or no

This was a lone visitor this morning at our peanut gallery. I can't tell what it is.

I used to think we were getting all crows at the nuts. Then someone told me we also have ravens. And pretty frequently we hear, unambiguously, ravens in the neighbourhood. So this may be a raven. Or a "craven" as the crosses are called.

EDIT, half-hour later:
"Maybe." But probably not.
A much more expert birding friend tells me the visual evidence here is of an American crow, not of a raven.
