You will get varying opinions even from bird 'experts'. Just say you got great photos of a white Barred Owl. 
Leucism is a genetic mutation of birds and other animals that prevents melanin and other natural pigments from being deposited normally. Leucism comes in two main varieties: paleness (an equal reduction of pigment in all feathers) and pied (an absence of pigment in some feathers creating white patches). Birds with extensive leucism have weaker feathers that will wear out more swiftly, making flight difficult. The weaker feathers also reduce some of the bird’s insulation.
Albinism results in the reduction of melanin production throughout the body. The easiest way to determine whether an animal is an albino or leucistic is by looking at eye color. Albinistic birds have pink colored eyes because without melanin in the body, the only color comes from the blood vessels behind the eye. It is possible for a leucistic bird to be completely white and still have normal colored eyes, because the eye pigments develop through a different pathway and aren’t altered by the genetic mutation that affects feathers....Show more →
