Leucistic Laysan Albatross chick on Midway Atoll, April 2025
A leucistic Laysan Albatross Phoebastria immutabilis chick was recently photographed on Midway Atoll. Author and photographer Joe Owen writes:
“While most albatross chicks are typically grey and black, leucism gives this one its striking, lighter plumage. This genetic condition reduces pigment, resulting in the pale feathers that make this chick truly unique. It is possible to tell the difference between leucistic and albinism; in this case, by the normal coloration T melof the chick's eye.”
