I agree with Udo. And in part with James and Shannon, I think. If I understood them correctly.

In my opinion, even if albinism is usually characterized by amelanism and hypomelanism (most notably in mammals and birds), it's a gross oversimplification to call an amelanistic or hypomelanistic animal an albino. As bad as calling a hypo-/anerythristic or hypo-/axanthic animal that.
