As I understand it, a true albino has no pigment at all, whereas a
leucistic individual has individual feathers or even entire tracts which
lack pigment, but pigment is present elsewhere. Lack of eye pigment would
be the way to figure out which is which. I have seen some nearly pure white
birds that were still not albino, including a Red-tailed Hawks and an
American Robin.
