Two photographs of adult Arctic Skuas placed side-by-side for comparison. The bird in the top photograph is a dark morph, with dark brown plumage all over its body and wings., The bird in the bottom photograph is a pale morph, with a dark brown back, wings and crown, and cream-coloured neck, chest and belly. Both these morphs occur in the same Arctic Skua breeding colonies.
