This habit greatly increases their food-collecting ability during bad weather when fish swim deeper, out of reach of plunge-diving terns, but still within reach of the deeper-diving Puffins. It often forages out in the ocean and nests on hard-to-visit islands. At close range, the adults have a dark blood-red bill, darker than that of Common Tern, with no black tip. Gochfeld, M. & Burger, J. Adults in breeding plumage are a shimmering chalky white overall, with pale gray upperwings, striking black cap, a blackish bill (mostly orange in Caribbean populations), and faintly rosy underparts. During breeding season, it has a black cap, a silvery gray back, and a white breast and belly lightly tinged with pink. In Australian territory, it has been recorded nesting alongside the black-naped tern (S. sumatrana), lesser crested tern (Thalasseus bengalensis), crested tern (T. bergii), fairy tern (Sternula nereis), bridled tern (Onychoprion anaethetus) and silver gull (Chroicocephalus novaehollandiae). While the core colonies of this species in Ireland and the UK are growing, it’s essential to think about the long-term future of the species and helping expand their range. The Roseate Tern breeds on coasts and islands in the tropics along the Indian, Pacific, and Atlantic oceans and in temperate zones of North America and Europe, South Africa, and western Australia. S. d. dougallii breeds on the Atlantic coasts of Europe and North America, and winters south to the Caribbean and west Africa. Ornithologists recognize three subspecies: dougallii of the Atlantic Ocean and Caribbean Sea, the smaller gracilis of most of the Indian Ocean, and korustes of the Indian Ocean around southern India and Sri Lanka, in which the bill is shorter and upperparts darker gray than in gracilis. The second population breeds from Florida and the Bahamas to the Lesser Antilles. They are shorter billed than Common Tern, with a small, rather round-looking head and a somewhat 'neckless' appearance. Roseate terns are found mainly in the northern hemisphere on North America’s northeastern coast, from Nova Scotia to Florida’s southernmost tip, as well as a number of islands in the Caribbean Sea, also northwestern Europe, west and south Africa, and Western Australia. One of the main reasons given in the UK plan for threat to the species is global warming, creating an alteration of vertical profile distribution for its food source fishes. Gulls, Terns, and Skimmers(Order: Charadriiformes, Family:Laridae). Both the European and North American populations have been in long term decline, though active conservation measures have reversed the decline in the last few years at some colonies, most notably at Rockabill Island off the coast of Dublin, Ireland, which now holds most of the European population (about 1200 pairs). [11], With their favouring partly hidden nest sites, the provision of nestboxes has proven a dramatic conservation success, with the birds taking to them very readily. Sterna dougallii . The roseate tern is a graceful, slender, medium-sized tern. The long-billed and short-winged S. d. gracilis breeds in Australia and New Caledonia. The tropical forms S. d. korustes and S. d. bangsi are resident breeders from east Africa across the Indian Ocean to Japan. Barcelona: Lynx Edicions. Long, forked tail white. They have more red on the bill. pp. The Canadian Wildlife Service lists the roseate tern as Threatened. At one colony on Coquet Island, Northumberland, the population rose from 25 pairs (1997) to 92 pairs (2005) after nestboxes were provided. Roseate Tern: Found in temperate and tropical habitats in the northern hemisphere, breeding in two distinct groups: the Northeast population, breeding from the Magdalen Islands of Quebec to Long Island in New York, and a population in the Caribbean Sea. In smaller colonies, they may rarely mate with these other tern species. The Rockabill tern colony in the Irish sea is managed by BirdWatch Ireland and consists of two granite islands: the Rock, and the Bill. The largest colony, more than 1,000 pairs, is located at Great Gull Island off eastern Long Island. This is a small-medium tern, 33–36 cm (13–14 in) long with a 67–76 cm (26–30 in) wingspan, which can be confused with the common tern, Arctic tern, and the larger, but similarly plumaged, Sandwich tern. Forages in ocean waters from coastlines to deep water. Back and wings pale grey and white with dark grey and black on leading edge of primaries. The Roseate Tern is a bird of elegant proportions and dazzling white breeding plumage, accented with a black cap, dark bill, and pale rosy breast. The Roseate Tern occurs on coasts and islands along the Atlantic, Indian and Pacific oceans. 624–667. This results in greatly increased breeding productivity with the protection given to the young from predatory birds like herring gulls. The Roseate Tern is also found in Atlantic coastal areas of Europe and North America. The Cornell Lab will send you updates about birds, birding, and opportunities to help bird conservation. State Status: Endangered Endangered . The white-bellied sea-eagle (Haliaeetus leucogaster) and silver gull are known to prey on eggs and chicks, while the turnstone (Arenaria interpres), black rat (Rattus rattus) and King's skink (Egernia kingii) are suspected predators.[9]. The r oseate tern is the rarest breeding seabird in the UK with only 13 1 pairs recorded in 2020. This species breeds in colonies on coasts and islands, at times with other seabirds. The Roseate Tern (Sterna dougallii) is a seabird of the tern family Sternidae. Tree, AJ (2005) The known history and movements of the Roseate Tern, "A phylogenetic framework for the terns (Sternini) inferred from mtDNA sequences: implications for taxonomy and plumage evolution", https://community.rspb.org.uk/getinvolved/wales/b/wales-blog/posts/celebrating-recent-successes-around-wales, Species text in The Atlas of Southern African Birds, https://en.wikipedia.org/w/index.php?title=Roseate_tern&oldid=983998891, Taxa named by George Montagu (naturalist), Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License, This page was last edited on 17 October 2020, at 15:16. During the late 1800s, however, roseate tern numbers declined drastically as human-related habitat degradation and unrestricted shooting nearly eliminated the species throughout its range.
