| Abstract |
The distribution and occurrence of the Great Skua in the North Sea is described using records made from ships and oil production platforms. The species was a summer migrant to the area and no birds were recorded between mid-November and late March. Most sightings were made in the vicinity of breeding colonies in Shetland and Orkney. The large immature component of the population probably caused the large influx to other areas of the North Sea. These young birds probably also accounted for seasonal changes in numbers at sea near breeding sites. Observations made on feeding behaviour agree with previous studies of Great Skua diet during the breeding season, and indicate that birds may be feeding mainly on sandeels in June and July, but discarded whitefish at other times. |
