Their nest is just a simple shallow scrape on the ground. Key words.-Royal Tern, Sterna maxima, chick diet, Fisherman Island, Virginia, prey switching. African populations may be vagrant within Europe. Diet: Feeds on small fish, but they also eat insects, shrimp, and crabs. Diet: Royal Terns eat fish, shrimp, small crabs, and occasionally squid. In some cases, tern eggs are laid directly on the ground, not in a scrape. The Elegant Tern feeds by plunge-diving for fish, almost invariably from the sea, like most Thalasseus terns. 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. 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. The slightly smaller T. m. albididorsalis lives on the coast of West Africa. Royal Terns mostly feed mostly on small fish - and to a lesser extent on squid, shrimp and crabs. , The royal tern usually feeds on small fish such as anchovies, weakfish, and croakers. When feeding they fly long distances from the colony to forage. P. A. Buckley and Francine G. Buckley. Waterbirds 24(3): 361-370, 2001 The breeding range of the Sandwich Tern  The royal tern is now placed in the genus Thalasseus that was erected by the German zoologist Friedrich Boie in 1822. A group of royal terns is known as a “highness.” Royal tern populations seriously declined in the late 1800s and early 1900s when eggs were used as food. This species has also wandered to Western Europe as a rare vagrant, these terns are probably from the American colonies. The royal tern feeds by diving into the water from heights near 30 feet (9.1 metres). Diet. Diet. 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. In the Americas, it occurs from southern California through to the Yucatan Peninsula and Mexico, on the Gulf and Atlantic coasts of the U.S. and the Caribbean, and also in south-eastern South America. They usually feed alone or in groups of two or three, b… The wintering range on the east coast is from North Carolina south to Panama and the Guianas, also the Caribbean islands. The royal tern plunges into the water and catches small fish and shrimp. Other threats involve: overfishing, human disturbance at nesting sites, egg collection, oil spills and discharge of chemicals and sewage into the sea, especially in the Rio de la Plata area in Argentina and Uruguay.

The royal tern is found in Europe, the Americas, and the Caribbean islands. A Royal tern remains with its parents for as long eight months after it hatches, an unusually long period amongst birds. The royal tern's length ranges from 45–50 cm (18–20 in) and their average weight is anywhere from 350–450 g (12–16 oz). It usually dives directly, and not from the "stepped-hover" favoured by the Arctic Tern. The entire breeding Both the male and the female incubate the egg for 30-31 days. the life cycle of the terns. , American birds migrate south to Peru and Argentina for the winter to escape the cold weather. When feeding they fly long distances from the colony to forage. The royal tern has an orange-red bill, pale grey upper parts and white under parts.  The royal tern feeds by diving into the water from heights near 30 feet (9.1 metres). 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. Sterna maxima, see Bridge et al., 2005) is a seabird in the tern family Sternidae. PROTECTION / THREATS / STATUS: Royal Tern populations decline in some parts of the range. A pair feeds only their own chick, managing to find it amongst the crowd, because they recognize its call. The Royal tern is the second biggest tern after the Caspian tern. 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. A group where chicks congregate together, known as a crèche, can number in the thousands. Nesting. 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. Royal and Sandwich tern adults partitioned food resources by prey species and prey size, while chick diet showed more overlap in prey species composition. The royal tern nests in large, dense colonies. Given their diverse diet of forage fishes high in the food chain, Royal Tern diet can be used to assess fish stock abundance and act as a potential bioindicator on the health of the local marine/estuarine ecosystem.  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. Recommended Citation. Diet / Feeding. 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. Minor details help distinguish this tern from its larger cousin. Inca terns follow fishing boats and often associate with whales and sea lions when feeding, stealing food from these fellow marine mammals.  The generic name is derived from the Ancient Greek Thalassa meaning "sea". 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. Diet / Feeding. The royal tern feeds in salt water and on very rare occasions in fresh water. Royal Terns eat mostly small (2–4-inch) fish and shrimp, which they capture by flying 20–30 feet above the water... Nesting. Its legs are black. About two weeks after hatching the chicks gather into groups called a crèche. The royal tern lives on the coast and is only found near salt water. Royal Tern. Animals such as foxes, raccoon, and large gulls prey on tern chicks and tern eggs. It is paler above than lesser crested tern and the yellow-billed great crested tern. The royal tern typically feeds in small secluded bodies of water such as estuaries, mangroves, and lagoons. Soft-shelled blue crabs are major items in diet on Atlantic Coast. Received 2 December 2000, accepted 8 February 2001.  The royal tern feeds on small crabs, such as young blue crabs that swim near the surface of the water. , The royal tern nests on island beaches or isolated beaches with limited predators. Royal and Sandwich tern diet closely reflected the species composition of trawls from … She either swallows it immediately or keeps it in her bill during the displays. The oldest royal tern was over 30 years old. The royal tern has few predators when it is mature, but before the chicks hatch or while they are chicks the tern is threatened by humans, other animals, and the tides. Feeds mostly on small fish (up to 4" long, sometimes up to 7") and crustaceans, especially crabs. Primary objectives were to document common prey species, annual and seasonal vari-ation in prey selection, and seasonal variation in prey size based on average bill length in this species. Royal terns rest on sandbars, beaches and mudflats, and are occasionally seen at inland lakes.  African birds may reach as far north as Spain. Status: Least Concern  When the chicks are a month old they fledge or start to fly. Chef David Pell provides guests with an array of freshly prepared seafood and steaks as well as seafood towers, carpaccios and tartares from our raw bar. The royal tern was originally placed in the genus Sterna; however, a 2005 study suggest that it is actually part of the genus Thalasseus.. We detected no age-related differences in Royal Tern prey size or selection; however, our sample was relatively small and further research is warranted. Habitat: They are found along coastal beaches. , "Diet of royal (Thalasseus Maximus) and sandwich (T.

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. Also, but less frequently, the royal terns will hunt for fish in open water, typically within about 100 metres (110 yards) off the shore. Also, but less frequently, the royal terns will hunt for fish in open water, typically within about 100 metres (110 yards) off the shore. 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. What I coincidence – I had a banded Royal Tern at Forsythe in early September that was banded on 7/17 near Chincoteague! Differences include juveniles having black splotched wings and a yellower bill. 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. This species is territorial and will defend its small space by flying or walking or towards intruders, by flutter flights, aerial chases, and a number of displays involving head movements. Their courtship displays take place either on the ground or in the air. The AEWA covers birds from 64 countries in Africa and Eurasia. Fish are their main source of food but they also eat insects, shrimp, and crabs. Royal Tern adults consumed significantly more Sciaenids than any other tern group, and Sandwich Tern adults consumed more Engraulids than any other tern group. It is presently classified as Thalasseus maximus, which places it with six other seabirds from the tern family. Usually, a male will bring a fish to the female. 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 … Description: Royal Terns are large and similar to Caspian Terns. , The royal tern typically feeds in small secluded bodies of water such as estuaries, mangroves, and lagoons. In winter, the black cap becomes patchy. A group of these birds is called a "highness" of terns. Royal and Sandwich tern diet closely reflected the species composition of trawls from nearby waters, suggesting opportunistic prey selection. Royal terns are carnivores (piscivores), they eat fish that average 6-7 cm in length, squid, shrimps and crabs. The royal tern feeds in salt water and on very rare occasions in fresh water. The largest is the Caspian tern. This species has a very large range, but the IUCN Red List and other sources do not provide the Royal tern total population size. In flocks of terns and gulls, it is usually easily identified by its size, its characteristic black crest and its bright orange bill. Eggs may be destroyed by sandy crabs. The Royal Tern (Thalasseus maximus, syn. Royal Tern (Sterna maxima) chick diet at Fisherman Island National Wildlife Refuge, Virginia, was in-vestigated in 2003 and 2004. The Royal tern occurs in both North and South America, as well as on Africa’s Atlantic coast. The Common Black-headed Gull takes eggs and chicks. It lives only along ocean beaches. About Located in the heart of Johns Island on Maybank Highway, The Royal Tern is a family restaurant and neighborhood eatery. Royal terns mature around the age of 4 years, after which they build their own nests and reproduce. This bird has two distinctive subspecies, T. m. maximus which lives on the Atlantic and Pacific coasts of the North and South America. Soon after hatching, chicks join a crèche or group with other young on the beach. Nests are 5 to 8 per sq. The Royal Tern Nestled in the heart of Johns Island, The Royal Tern is a family restaurant and neighborhood eatery. 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). This bird has two distinctive subspecies: T. m. maximus which lives on the Atlantic and Pacific coasts of the North and South America. Breeding: Lays 1 or 2 eggs. Unlock thousands of full-length species accounts and hundreds of bird family overviews when you subscribe to Birds of the World. This bird is gregarious, and breeds in colonies and roosts in flocks. Their bill is bright orange-red, but a different shade of red than Caspian Terns. Its bill also becomes somewhat paler in the non-breeding season. They are reproductively mature at 3-4 years.  When the chicks are in the crèche, they are primarily fed by their parents who recognize their offspring by their voice and looks. However, its preferred breeding sites are often at risk of flooding, and a potential threat is contamination of its prey by pesticides. African and North American populations typically breed from April to August, and in South America it is between October and March. The royal tern also uses this technique when hunting flying fish. The AEWA covers 255 species that depend on wetlands for part of their life. The royal tern has a red-orange bill and a black cap during the breeding season, but in the winter the cap becomes patchy. This is a large tern, second only to Caspian tern but is unlikely to be confused with the carrot-billed giant, which has extensive dark under wing patches. Royal Terns usually forage alone or in groups around estuaries, lagoons and mangroves. Both genders look alike. Royal terns are carnivores (piscivores), they eat fish that average 6-7 cm in length, squid, shrimps and crabs. Eats wide variety of small fish, also shrimp, squid. 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. The royal tern's conservation status is listed as of least concern. The breeding plumage is a black crown with a distinctive black shaggy crest. The royal tern was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1781 in his Histoire Naturelle des Oiseaux from a specimen collected in Cayenne, French Guiana. The taxonomy of the royal tern has been debated, whether the correct scientific name was Thalasseus maximus or Sterna maxima. Tern nesting sites can also be affected by the tides; if a tern colony has nested too close to the high tide mark a spring tide would flood the nesting site and kill the chicks and make unhatched eggs infertile. , The calls of the royal tern are usually short, clear shrills. The diets of both tern species contained a variety of demersal prey items indicating use of discards from local fisheries activities. 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. 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..  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.

Key Words.-Foraging ecology, Royal Tern, Sandwich Tern, North Carolina, stable isotopes, Sterna maxima, Ster-na sandvicensis. Charadriiformes are mainly seabirds of small to medium-large size. According to the All About Birds resource, the total breeding population size of the Royal tern on the North American continent is 100,000-150,000 birds. Over 2200 The elegant tern has a longer more curved bill and shows more white on the forehead in winter. The purpose of this study was to … 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. The offering of fish by the male to the female is part of the courtship display. In various parts of its range, the royal tern could be confused with the elegant tern, lesser crested tern (the other orange-billed terns), and the greater crested tern.
