	Arctic Skua - Wikipedia, the free encyclopedia
		The Arctic Skua, Stercorarius parasiticus, known as Parasitic Jaeger in North America, is a seabird in the skua family Stercorariidae.
		Like the larger skua species, it continues this piratical behaviour throughout the year, showing great agility as it harasses its victims.
		Identification of this skua is complicated by its similarities to Long-tailed Skua and Pomarine Skua, and the existence of three colour phases.

	Abstract (Site not responding. Last check: 2007-10-07)
		The influence of territory density on the vulnerability of Arctic skuas Stercorarius parasiticus to predation.
		The distribution of Arctic skua territories on Foula changed markedly between 1976 and 1999, with a disproportionately large decline occurring in most of the northern half of the island.
		This is particularly relevent in the light of recent concerns that the impact of great skua predation on other seabirds, including Arctic skuas, is unacceptably high in Shetland, and that some degree of population management should be considered.

	Long Tailed Skua
		The distinction between the Arctic Skua and the Long Tailed Skua are the tail feathers of the Long Tailed Skua.
		Skuas breed along the sea coasts and inland away from the sea and they breed on the bare ground at high altitudes and when they migrate they fly to the opposite hemisphere.
		While the Skua are in their winter quarters they spend all their time at sea though they will settle on drifting objects, on the shore at times and in the southern hemisphere will perch on ships.

	Arctic Skua
		In Britain the Arctic Skua is confined to breeding in north and west Scotland, at the southern extremity of its circumpolar, high latitude breeding range.
		Counting Arctic Skuas is made difficult by the scattered nature of territories in many areas â“ in Mainland Shetland and Caithness, single pairs may be scattered, often considerable distances from the coast and might be easily overlooked.
		Breeding success of Arctic Skuas in Shetland was also poor in 2000 and 2001, and birds that lost eggs early on may have shown low attendance in the territory, so that some breeding AOTs may also have been missed.

		Pomarine and Arctic Skuas have been seen in the spring but only in very small numbers, partly because the area is under-watched at this time of the year.
		Pomarine Skua is circumpolar in distribution, breeding on tundra habitat north of the Arctic Circle.
		Arctic Skua has a circumpolar breeding distribution and is the commonest European skua species They breed in a large range of climactic zones from cool temperate (e.g.

	SKUA FACTS AND INFORMATION (Site not responding. Last check: 2007-10-07)
		Skuas nest on the ground in temperate and arctic regions and are long-distance migrants.
		Skuas are related to gulls, waders, auks and skimmers.
		The skuas are often split into two genera with only the smaller species retained in ''Stercorarius'', and the large species transferred to ''Catharacta'', but there is no real genetic basis for this separation.

		The arctic skua breeds in the northern hemisphere, on open spaces inland, on coastal flats and islands, from the Arctic circle to as far south as northern Scotland.
		The arctic skua migrates south around September and passes through the tropics to winter in the southern hemisphere.
		They are common in New Zealand waters from November — April and, during that time, are the most numerous skua seen off the coasts of the mainland and the Chatham Islands.

		Jonathan had discovered a pair of Arctic Skuas which had nested on the debris fan close to the river from Vatnsdalur but I suggested that the hide, which by now seemed to have been manned by just about everyone in the camp, should be abandoned.
		The Skua spotted us when we were still about fifty metres away from the nest and they began circling overhead.

		It was possible that the Skua had roosted overnight on the water at the rear of the old Bilsthorpe pit top and had moved off at the onset of the clearer weather.

	Skuas and Jaegers
		Skuas are closely related to gulls, terns, skimmers, and alcids; indeed, some authors follows Sibley and Monroe (1990) in considering them simply a tribe (not even a subfamily) of an expanded Laridae family.
		Although related to gulls, all the skuas show adaptations associated with their piratical and predatory way of life, and with their breeding at high latitudes close to both poles.
		While any particular jaeger or skua may chase most any bird that has food, here on Monterey Bay the migrations of the three jaegers are closely tied with the migrations of three smaller seabirds.

		A small skua was found on the beach at Huttoft and the initial impression was that it was in some difficulty for it seemed very inactive and reasonably approachable.
		Although a Long-tailed Skua was considered, this identification was dismissed as the plumage features on the bird were scrutinised and evaluated.
		Owing to the strength of barring on the flanks and undertail-coverts and the strength of the fringing of the upperparts feathers, the bird was aged as a juvenile.

		Great skuas have arguably the highest conservation value of any British bird, with 60% of the world population, whilst >10% of all Arctic skuas breed in Britain.
		This project will determine the climate response surfaces of Arctic and great skuas and will use these, both to model the observed range changes of the two species over the past 30 years and to predict future distributions for both species.
		Hence climate response surfaces will also be generated for a wide range of other such species including southern-hemisphere skuas, and used to predict changes in their distributions under a range of future climate scenarios.
