Exempel på hur man kan använda SKUAS i en mening

• The three smaller skuas, the Arctic skua, the long-tailed skua, and the pomarine skua, are called jaegers in North American English.
• The ibisbill belongs to the order Charadriiformes which also includes the sandpipers, plovers, terns, auks, gulls, skuas and others.
• Baker and colleagues found that the Laridae lineage diverged from a lineage that gave rise to both the skuas (Stercorariidae) and auks (Alcidae) before the end of the Cretaceous in the age of dinosaurs.
• The suborder Lari is the part of the order Charadriiformes that includes the gulls, terns, skuas and skimmers; the rest of the order is made up of the waders and snipes.
• In poor lemming years, predatory species such as skuas and snowy owls take Arctic-breeding waders instead.
• Poor weather can lead to high mortality rates among eggs and chicks and they are also preyed on by skuas and sheathbills.
• The parasitic jaeger is now placed with the six other skuas in the genus Stercorarius that was introduced in 1760 by the French zoologist Mathurin Jacques Brisson.
• The most likely explanation is extensive hybridization between the great and one species of lesser skuas, which resulted in a hybrid population that eventually evolved into a distinct species, the pomarine jaeger; or alternatively between the pomarine and a species of Southern Hemisphere skua, with the great skua being the hybrid offspring, perhaps appearing as recently as the 15th century.
• The behavior occurs, too, in vertebrates including birds such as skuas, which persistently chase other seabirds until they disgorge their food, and carnivorous mammals such as spotted hyenas and lions.
• It spends the rest of the year at sea and strictly nocturnal at the breeding sites to avoid predation by gulls and skuas, and will even avoid coming to land on clear moonlit nights.
• This storm petrel is strictly nocturnal at the breeding sites to avoid predation by larger and more aggressive gulls and skuas.
• Predators of the king penguin include giant petrels, skuas, the snowy sheathbill, the leopard seal, and the orca.
• The Shiant Islands have a large population of seabirds, including tens of thousands of Atlantic puffins that breed in burrows on the slopes of Garbh Eilean, and significant numbers of common guillemots, razorbills, northern fulmars, black-legged kittiwakes, common shags, gulls and great skuas.
• The skuas, fat and dark in colour with white wingtips, are said to be aggressive "pirates of the seas", which harass other birds as big as gannets.
• Depending on the season, birds may include fulmars, guillemots, kittiwakes, puffins, great skuas, arctic skuas, razorbills, and - at sea - gannets and herring gulls.
• Other birds nesting at the site in smaller numbers include Adélie penguins, imperial shags, Wilson's storm petrels and south polar skuas.
• A wide array of seabirds have been recorded in the strait, including approximately 54 different species in various families: penguins (4 species), albatrosses and mollymawks (7 species), shearwaters, petrels, and prions (25 species), gannets and shags (6 species), skuas, gulls and terns (12 species).
• Malin Head is an ideal vantage point from which to view the autumnal movements of seabirds such as gannets, shearwaters, skuas, auks and others, on their southward migration flights.
• Distinguishing this skua from the Northern Hemisphere Arctic, pomarine, and long-tailed skuas is relatively straightforward.
• Birds for which the IBA has conservation significance include northern rockhopper penguins (30,000 breeding pairs), Tristan albatrosses (1,500–2,000 pairs), sooty albatrosses (5,000 pairs), Atlantic yellow-nosed albatrosses (5,000 pairs), broad-billed prions (1,750,000 pairs), Kerguelen petrels (20,000 pairs), soft-plumaged petrels (400,000 pairs), Atlantic petrels (900,000 pairs), great-winged petrels (5,000 pairs), grey petrels (10,000 pairs), great shearwaters (100,000 pairs), little shearwaters (10,000 pairs), grey-backed storm petrels (10,000 pairs), white-faced storm petrels (10,000 pairs), white-bellied storm petrels (10,000 pairs), Antarctic terns (500 pairs), southern skuas (500 pairs), Gough moorhens (2,500 pairs), and Gough buntings (3,000 individuals).
