As an amatuer birder and amatuer photographer, I agree, nice shot/nice bird. As to the color, we get mostly Scrub Jays out here (Oregon), which have a different set of shadings. That said, a quick review of my bird books and a couple birding sites show a range of bluish shading (including none) on this bird's white parts. Of course, those photos could have had incorrect WB as well. FWIW.
