Leucistic or Albino?

Snowy the white Australian Magpie has taken up residence at Washerwomans beach on the beautiful New South Wales South Coast. Unusual whiteness in birds such as Snowy can occur because of two different causes: leucism and albinism.

Leucism is a genetic mutation that prevents the pigment melanin from being properly deposited on a bird’s feathers. Albinism affects all pigments and albino birds show no color whatsoever in their feathers, skin or eyes. Snowy has very pale legs and bill but dark eyes and some small dark marks.
