Common Tern

This medium-sized tern is 34-37 cm long with a 70-80 cm wingspan. It is most readily confused within its range with the similar Arctic Tern , Roseate Tern , Antarctic Tern and South American Tern .

The Common Tern is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.

Common Tern (Sterna hirundo), a bird listed as Endangered in Wisconsin, prefers the Great Lakes' shorelines, bays, sand bars of large lakes and rivers, sandy or rocky coastal islands, and marshes. The breeding season extends from mid-May through late September. Status and NHI Documented Occurrences in Wisconsin The table below provides information about the protected status (State and Federal Status) and the rank (S and G Ranks) for Common Tern (Sterna hirundo).

The Common Tern (Sterna hirundo) is a seabird of the tern family Sternidae. This bird has a circumpolar distribution breeding in temperate and sub-Arctic regions of Europe, Asia and east and central North America. It is strongly migratory, wintering in coastal tropical and subtropical regions. It is sometimes known as the sea swallow. Contents - * 1 Description * 2 Behaviour * 2. More

Currently, the Common Tern is one of the main duties of management: one of the most important parts of managing for terns is to collect data to gain further knowledge on this species. During the summer of 1998, three studies were performed on Common Terns located on the north part of South Monomoy Island. This paper focuses on one of those studies, which is analyzing the productivity of Common Terns. More

note 3 : beginning July 2004 one of the Common Terns first c-ringed in 2002 is feeding 2 of that year chicks. Also in this period 16 chicks were ringed (15 on the rafts, 1 plucked from the water just before a Carrion Crow got to it). Five birds were found dead on the rafts. More

The Common Tern is a medium-sized seabird that is sometimes also called a “sea swallow” due to its diving abilities and affinity for water habitats. This species forms large colonies for breeding, and does so in temperate and sub-Arctic climates throughout Europe, Asia and eastern and central North America. In winter months, the Common Tern will migrate to subtropical and tropical ocean coastlines. Breeding takes place along the coasts and on islands of inland lakes. More

Like all Sterna terns, the Common Tern feeds by plunge-diving for fish, from either the sea or freshwater lakes and large rivers. It usually dives directly, and not from the "stepped-hover" favoured by Arctic Tern. The offering of fish by the male to the female is part of the courtship display. Common terns are known to reach an age of 23 years or more on occasion (Austin, 1953). The old Scottish word for the Common Tern is pictar, occasionally encountered in Scotland and the Maritime Provinces of Canada. More

Common Tern, it has a longer tail and mono-coloured bill, while the main differences from the Roseate are its slightly darker colour and longer wings.

This bird's closest relatives are a group of South Polar species, the South American (Sterna hirundinacea), Kerguelen (S. virgata), and Antarctic (S. vittata) Terns. More

The Vermont state endangered Common Tern (Sterna hirundo) population nests on 1-6 small islands in Lake Champalin's Inland Sea. This graceful, fish-eating bird was first documented on the lake on Popasquash Island in the late 1800's. During the 1960's the population spread to other sites including Rock (St. Albans), Grammas, Hen, Gull Rock and Savage islands. The number of birds using each island fluctuates from year to year with Popasquash and Rock islands being the predominate nesting sites in recent years. More

A graceful, black-and-white waterbird, the Common Tern is the most widespread tern in North America. It can be seen plunging from the air into water to catch small fish along rivers, lakes, and oceans. More

Common terns nest on Assateague and may be best spotted from spring through fall (most winter from Florida southward). It's seldom that you can cross the small bridge to Assateague where this photo was taken without spotting several terns eyeing the water from the bridge-side. Terns feed on small fish which they catch with a sudden, arrow-like plunge. Sometimes they will even swim a few feet under water to catch their prey. More

During the breeding season, the Common Tern primarily feeds on live prey, but during the winter, it will eat dead fish and bait discarded by fishermen. One bird can dive and attract up to 1,000 other birds from 1 kilometer away to form a very efficient foraging flock over schools of predatory fish. Frequently tries to steal fish from Arctic Terns and Least Terns. Larger chicks often take food from smaller chicks and sometimes form gangs to prevent smaller chicks from gaining access to food.

* Comments: By the 1870s, populations of Common Terns were decimated by the millinery trade but rebounded in the 1930s due to protection brought about by the Migratory Bird Treaty Act. However, they fell again when the effects of DDT and competition with gulls for limited breeding sites affected their breeding opportunities and success. More

Common TernThe Common Tern has become one of Vermont’s greatest wildlife conservation victories. Once the most prevalent tern in the Lake Champlain basin, their numbers dropped from almost 400 nesting pairs in the 1960s to only 50 in 1988. As a result, the Common Tern was placed on the Vermont Endangered species list in 1989. Since 1978, the Lake Champlain Land Trust has worked intently to permanently conserve and protect several important Common Tern nesting islands in Lake Champlain. More

Common Tern – Hollow, rotomolded polyethylene, 1” hole for wooden dowel or plastic plug. - Common Terns were first used in 1995 by the National Audubon Society Seabird Restoration Program on Petit Mannan Island National Wildlife Refuge to bring this species back to an historical nesting area. Birds responded by nesting in the decoy colony and a replacement colony was established. The decoys were then moved to Pond Island at the mouth of the Kennebec River to re-establish a colony there.
