I jumped on the Google and found this entry, "Notes on some Albino birds in Maryland...," from
The Oölogist: for the student of birds, their nests and eggs, Volume 16, no. 9,a book edited and published by Frank H. Lattin in 1899. The information covering the American Crow begins on the bottom rh column of p. 129 (below) and continues on the top lh of p. 130.
Albino crows do not have to be all white. They can range in color from solid light blue to mottled black & white, as the one above, or mottled black, brown, & white with a blue tinge in the white parts. The albino crows cited in the book lived in this area at the turn of the last century, but this is the first one Linda has ever seen. I've never seen one, period. Kinda cute.
