Pine Grosbeak

I got this email from Mary Whitley today, about the bird i posted yesterday.
Thanks Mary and Cameron!
And thanks Rien and Cicero, you both knew anyway.

Hi Mary,

Cool photos. Let Jozien know that it is a leucistic (partial albino) Pine Grosbeak. They turn up from time to time as well as leucistic redpolls, siskins, juncos, and a fairly long list of other species. The cause may be genetic or possibly environmental (nutrition, stress, etc).
