Help with ID (crow or raven perhaps, but with white on wing)

[Colin Chisholm]

This shot was taken mid March 2010 on the south rim of the Grand Canyon.
It is more of a scenic shot, the bird is rather small.
But I have provided below the full size image on Flickr, so hopefully it is enough to ID this bird...maybe.

I would have assumed it is a crow or raven, but I am not sure why it would have the white on the wings.

Anyone have any ideas on what this might be?

Regards,
Colin

Hi Colin. This looks to me to be a leucistic Common Raven. Nice canyon scenic

White feathers in corvids (ravens, crows, jays) are not an unusual occurrence in North America. I've seen one with a complete white wing stripe at the base of the flight feathers. If you do a search for "piebald crows", you'll see a number of sites that show odd crows that were taken by hunters.

Dan, and Paul -
Thanks for the quick replies and the education about "corvids" & "leucism".

Regards,
Colin

PS: Beautiful place, the Grand Canyon. I have to go back again some day for a longer stay.
