The Herring Gull Larus argentatus is widely distributed through much of North America and the Western Palearctic (Vaurie 1965, Harrison, 1983, Grant 1986). It occurs of all the archipelagos of Macaronesia except the Cape Verde Islands, where it is only an iccasional visitor (Bannerman & Bannerman 1968). Some 2000 pairs nest on the Azores and it is widespread in small, but unknown numbers on Madeira (Le Grand et al. 1984). On the Desertas, Le Grand et al. (1984) mentioned a large colony on Chao, as well as some old nests on Deserta Grande and Bugio in 1981, whilst a brief visit to Porto Santo in 1981 found breeding in only limited numbers. It seems to be relatively scarce on the Selvagens where Jouanin (1974) found 10 nests on Selvagem Grande during 1973 and Jensen (1981) estimated the size of the colony at 15-30 pairs, figures which agree with the observations of Hartog et al. (1984). On Selvagem Pequeña, Le Grand et al. (1984) counted 5-10 pairs.
