This white pigeon/dove appeared in my yard about a week ago and has been here ever since. It is quite friendly, does not shy away from the camera, and seems to have adopted us as its new family. I think it may be leucistic as it did appear to have some coloration in the eyes. (South central Louisiana)
Postscript—My friend left after being with us for nine or ten days; I think it was the fireworks in the neighborhood that scared it away on the Fourth of July 2013. SO sad to see it depart but SO happy I was able to have this lovely bird with me for a spell.
