POLYMORPHISM IN THE ARCTIC SKUA STERCORARIUS PARASITICUS IN ICELAND
Summary. A survey of the frequency of the dark and light colour forms of the Arctic Skuas breeding in Iceland provided evidence of a south‐north cline, the light form being more frequent in the north than in the south. In one area there were significantly more dark birds in 1971 than 30 years earlie...
