[2] The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. The AEWA covers 255 species that depend on wetlands for part of their life. Royal and Sandwich tern diet closely reflected the species composition of trawls from nearby waters, suggesting opportunistic prey selection. [9], "Diet of royal (Thalasseus Maximus) and sandwich (T. Sandvicensis) terns during the Austral winter in the Buenos Aires Province, Argentina", "Ground-Nesting Waterbirds and Mammalian Carnivores in the Virginia Barrier Island Region: Running out of Options", https://en.wikipedia.org/w/index.php?title=Royal_tern&oldid=982017643, Native birds of the Eastern United States, Native birds of the Southeastern United States, Articles with dead external links from December 2017, Articles with permanently dead external links, Taxonbars with automatically added original combinations, Creative Commons Attribution-ShareAlike License, This page was last edited on 5 October 2020, at 18:35. Royal Tern adults consumed significantly more Sciaenids than any other tern group, and Sandwich Tern adults consumed more Engraulids than any other tern group. The Royal tern is a diurnal animal and it feeds alone or with a small group, by flying several meters above the water’s surface and then diving, but it does not submerge. Feeds mostly on small fish (up to 4" long, sometimes up to 7") and crustaceans, especially crabs. Life Cycle. [16][17] When the chicks are a month old they fledge or start to fly. Royal Terns eat mostly small (2–4-inch) fish and shrimp, which they capture by flying 20–30 feet above the water... Nesting. The eggs incubate from 25 to 30 days; after the eggs hatch the chicks remain in the scrape for about a week. [16] Nests are 5 to 8 per sq. Some of the shrills sound like kree or tsirr; the royal tern also has a more plover like whistle that is longer, rolling and is more melodious.[11]. Colonies are vulnerable to flooding and egging. Its bill also becomes somewhat paler in the non-breeding season. African and North American populations typically breed from April to August, and in South America it is between October and March. They tend to feed near the shore, close to the beach or in backwater bays. The royal tern is also in the family Sternidae because of its white plumage, black cap on its head, long bill, webbed feet, and bodies that are more streamlined than those of gulls. Habitat: They are found along coastal beaches. Their courtship displays take place either on the ground or in the air. PROTECTION / THREATS / STATUS: Royal Tern populations decline in some parts of the range. Nests in colonies. The royal tern feeds in salt water and on very rare occasions in fresh water. Royal Tern Sterna maxima Description: 18-21" Crow-sized, large tern with long, heavy, yellow-orange to orange-red bill, black cap, pale gray back and wings, white forehead, tail forked, similar Caspian Tern … What I coincidence – I had a banded Royal Tern at Forsythe in early September that was banded on 7/17 near Chincoteague! [14], Like all white terns, it is fiercely defensive of its nest and young. Royal and Sandwich tern diet closely reflected the species composition of trawls from … The Royal tern is the second biggest tern after the Caspian tern. [10], The calls of the royal tern are usually short, clear shrills. The Royal Tern (Thalasseus maximus, syn. During their entire life cycles, Royal Terns inhabit warm coastal marine waters, and they normally rest and... Food. In the Americas, the royal terns on the east coast, during the breeding season (April to July), occur in the US north to Virginia, occasionally drifting north to Long Island, New York. The royal tern also uses this technique when hunting flying fish. Each species account is written by leading ornithologists and provides detailed information on bird distribution, migration, habitat, diet, sounds, behavior, breeding, current population status, and conservation. They are often observed flying several meters above the surface of water and diving. [9] Juvenile royal terns are similar to non-breeding adults. Diet: Royal Terns eat fish, shrimp, small crabs, and occasionally squid. The elegant tern has a longer more curved bill and shows more white on the forehead in winter. Its legs are black. A group of these birds is called a "highness" of terns. [18] Humans threaten terns by fishing and by disrupting the tern nesting sites. Fish are their main source of food but they also eat insects, shrimp, and crabs. Currently this species is classified as Least Concern (LC) and its numbers today remain stable. Soft-shelled blue crabs are major items in diet on Atlantic Coast. Diet: Feeds on small fish, but they also eat insects, shrimp, and crabs. Royal Terns fly gracefully and slowly along coastlines, diving for small fish, which they capture with a swift strike of their daggerlike bills. The purpose of this study was to … In some cases, tern eggs are laid directly on the ground, not in a scrape. The royal tern nests in large, dense colonies. north American and African populations: April-August, south American populations: October-March, 2. In 1999 we also monitored a sample of 48 color-banded, known-age breeding birds ranging in age from 6––17 years to assess variations in diet with age. The royal tern has a red-orange bill and a black cap during the breeding season, but in the winter the cap becomes patchy. However, its preferred breeding sites are often at risk of flooding, and a potential threat is contamination of its prey by pesticides. The royal tern is found in Europe, the Americas, and the Caribbean islands. The wintering range on the east coast is from North Carolina south to Panama and the Guianas, also the Caribbean islands. Aspects of foraging and breeding ecology of the Royal Tern, Sterna[=Thalasseus]maxima, Common Tern, Sterna hirundo, and Black Skimmer, Rynchops niger, were compared in light of the food resource. Description: Royal Terns are large and similar to Caspian Terns. [14] They usually feed alone or in groups of two or three, but on occasion they feed in large groups when hunting large schools of fish. Fishing nets can catch a tern while it is diving, making it unable to feed or it may cause it to drown if it is caught under water. It is presently classified as Thalasseus maximus, which places it with six other seabirds from the tern family. The diets of both tern species contained a variety of demersal prey items indicating use of discards from local fisheries activities. A group where chicks congregate together, known as a crèche, can number in the thousands. [20] There are little other conservation efforts because the royal tern's status is of least concern. The reason there is little concern for the extinction of the royal tern is that the species has not experienced a significant enough decrease in population to become threatened or endangered. Breeding: Lays 1 or 2 eggs. She either swallows it immediately or keeps it in her bill during the displays. It may also perform aerial skimming to scoop up offal by surface-dipping, and will also take food from other terns; other seabirds do this too. These birds winter on the Pacific Coast, in Washington to Peru, and from Texas on the Atlantic Coast through the Caribbean and to southern Brazil. Diet. In flocks of terns and gulls, it is usually easily identified by its size, its characteristic black crest and its bright orange bill. About Located in the heart of Johns Island on Maybank Highway, The Royal Tern is a family restaurant and neighborhood eatery. The Royal tern occurs in both North and South America, as well as on Africa’s Atlantic coast. Note that images and other media featured on this page are each governed by their own license, and they may or may not be available for reuse. They are reproductively mature at 3-4 years. Also, but less frequently, the royal terns will hunt for fish in open water, typically within about 100 metres (110 yards) off the shore. The greater crested often associates with the lesser crested tern, but is 25% larger than the latter, with a proportionately longer bill, longer and heavier head, and bulkier body. The royal tern feeds by diving into the water from heights near 30 feet (9.1 metres). A sleek seabird of warm saltwater coasts, the Royal Tern lives up to its regal name with a tangerine-colored bill and ragged, ink-black crest against crisp white plumage. Royal Tern Life History Habitat. Primarily a coastal species, this bird is typically found in inshore waters, lagoons, bays, harbors, estuaries, mangroves and salt marshes. The offering of fish by the male to the female is part of the courtship display. [3] Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Sterna maxima in his catalogue of the Planches Enluminées. [5][6] The generic name is derived from the Ancient Greek Thalassa meaning "sea". Waterbirds 29(3): 395-400, 2006 In North America, the Royal Tern (Sterna maxima) is a conspicuous colonial-nesting waterbird that primarily breeds on barrier is-lands or man-made dredge islands along the mid-Atlantic seaboard. Results agree with previous stud-ies which indicate that birds are the main food resource of Peregrine Falcons (Oro & Tella 1996, White et al. Over 2200 While the chicks are in the crèche, they usually roam freely around the colony. Royal terns mature around the age of 4 years, after which they build their own nests and reproduce. Key Words.-Foraging ecology, Royal Tern, Sandwich Tern, North Carolina, stable isotopes, Sterna maxima, Ster-na sandvicensis. Royal terns rest on sandbars, beaches and mudflats, and are occasionally seen at inland lakes. Royal terns are carnivores (piscivores), they eat fish that average 6-7 cm in length, squid, shrimps and crabs. Disclaimer: The Animal Diversity Web is an educational resource written largely by and for college students.ADW doesn't cover all species in the world, nor does it include all the latest scientific information about organisms we describe. Their bill is bright orange-red, but a different shade of red than Caspian Terns. [12], American birds migrate south to Peru and Argentina for the winter to escape the cold weather. [9] African birds may reach as far north as Spain. It breeds on sandy, barren beaches, man-made islands and offshore coral islands. Royal Tern (Sterna maxima) chick diet at Fisherman Island National Wildlife Refuge, Virginia, was investigated in 2003 and 2004. Diet / Feeding. On the western coast of the Americas, the royal tern spends the breeding season from the US state of California to Mexico, wintering from California south to Peru. This bird is gregarious, and breeds in colonies and roosts in flocks. [12], The royal tern typically feeds in small secluded bodies of water such as estuaries, mangroves, and lagoons. Over one million pairs of seabirds breed annually on the Houtman Abrolhos island group, off the mid‐western coast of Australia, the largest seabird breeding station in the eastern Indian Ocean. A Royal tern defecates directly onto the rim of its nest, perhaps to reinforce it against flooding, as in a few weeks, the rim of the nest hardens. Their populations have since made a substantial comeback in the 20th century. Soon after hatching, chicks join a crèche or group with other young on the beach. The royal tern and the Cayenne tern nest and breed together in Argentina and Brazil.[18]. The royal tern feeds in salt water and on very rare occasions in fresh water. [13], The royal tern usually feeds on small fish such as anchovies, weakfish, and croakers. [14] When the chicks are in the crèche, they are primarily fed by their parents who recognize their offspring by their voice and looks. The Royal tern usually forages no more than 100 meters from the shoreline, but often this will be up to 30-40 km distant from the colony. This bird has two distinctive subspecies: T. m. maximus which lives on the Atlantic and Pacific coasts of the North and South America.

Royal Terns mostly feed mostly on small fish - and to a lesser extent on squid, shrimp and crabs. Inca terns follow fishing boats and often associate with whales and sea lions when feeding, stealing food from these fellow marine mammals. Status: Least Concern Royal Tern (Sterna maxima) chick diet at Fisherman Island National Wildlife Refuge, Virginia, was in-vestigated in 2003 and 2004. About two weeks after hatching the chicks gather into groups called a crèche. Sterna maxima, see Bridge et al., 2005) is a seabird in the tern family Sternidae. The royal tern belongs to the class Aves and the order Charadriiformes. Alterna- tively, if the shift in Royal Tern diet from mul- let in 1999 to tonguefish and squid in 2000 is real, it suggests that prey switching occurred perhaps due to changing availability of spe- cific forage species. When feeding they fly long distances from the colony to forage. Usually, a male will bring a fish to the female. Food: Fish constitutes the bulk of the diet for Royal … Diet. The Inca tern is a diurnal, gregarious species, living and nesting in large colonies numbering several thousand birds, often close to gull colonies. Cathy Adair November 24, 2019 at 5:04 pm Corey, I have a photo of a royal tern that I took 10-14-19 at Huntington Beach State Park , SC Also known as Murrells Islet. Differences include juveniles having black splotched wings and a yellower bill. The diet of Royal Terns was mainly of two species, the Argentine Anchovy and the silverside O. argentinensis, although the former was clearly the dominant prey. A pair feeds only their own chick, managing to find it amongst the crowd, because they recognize its call. African populations may be vagrant within Europe. Royal Terns usually forage alone or in groups around estuaries, lagoons and mangroves. This species has a very large range, but the IUCN Red List and other sources do not provide the Royal tern total population size. A Royal tern remains with its parents for as long eight months after it hatches, an unusually long period amongst birds. It lives only along ocean beaches. Royal Tern. An adult royal tern has an average wingspan of 130 cm (51 in), for both sexes, but their wingspan can range from 125–135 cm (49–53 in). In Africa, the royal tern breeds on the west coast from Mauritania to Guinea, and winter from Morocco and the Straits of Gibraltar to Namibia.
