3 white Greylag Geese. The question is, are they leucistic or albino? Collins Bird Guide (2022, Svensson et al): LEUCISM - innate pigment deficiency leading to pale, washed-out colours of the plumage; ALBINISM - innate lack of pigment, usually in the feathers, leading to partly or completely white plumage. So these birds are albino, and the above definition still lets them have coloured legs and bill and orbital ring.
