Sternula
''Sternula'' is a genus of small white terns. It is often subsumed into the larger genus ''Sterna'', although the most recent changes to the AOU checklist considers it a separate genus. The genus name is a diminutive of ''Sterna ''Sterna'' is a genus of terns in the bird family Laridae.

Least Tern
The least tern (''Sternula antillarum'') is a species of tern that breeds in North America and locally in northern South America. It is closely related to, and was formerly often considered conspecific with, the little tern of the Old World. Other close relatives include the yellow-billed tern and Peruvian tern, both from South America. It is a small tern, long, with a wingspan of , and weighing . The upper parts are a fairly uniform pale gray, and the underparts white. The head is white, with a black cap and line through the eye to the base of the bill, and a small white forehead patch above the bill; in winter, the white forehead is more extensive, with a smaller and less sharply defined black cap. The bill is yellow with a small black tip in summer, all blackish in winter. The legs are yellowish. The wings are mostly pale gray, but with conspicuous black markings on their outermost primaries. It flies over water with fast, jerky wingbeats and a distinctive hunchback appearan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fairy Tern
The fairy tern (''Sternula nereis'') is a small tern which is native to the southwestern Pacific. It is listed as " Vulnerable" by the IUCN and the New Zealand subspecies is " Critically Endangered". There are three subspecies: * Australian fairy tern, ''Sternula nereis nereis'' (Gould, 1843) – breeds in Australia * New Caledonian fairy tern, ''Sternula nereis exsul'' ( Mathews, 1912) – breeds in New Caledonia * New Zealand fairy tern, ''Sternula nereis davisae'' ( Mathews & Iredale, 1913) – breeds in northern New Zealand Description The fairy tern is a small tern with a white body and light bluish-grey wings.A small black patch extends no further than the eye and not as far as the bill. In the breeding plumage both the beak and the legs are yellowish-orange. During the rest of the year the black crown is lost, being mostly replaced by white feathers, and the beak becomes black at the tip and the base. The sexes look alike and the plumage of immature birds is similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Little Tern
The little tern (''Sternula albifrons'') is a seabird of the family Laridae. It was formerly placed into the genus ''Sterna'', which now is restricted to the large white terns. The genus name is a diminutive of ''Sterna'', "tern". The specific ''albifrons'' is from Latin ''albus'', "white", and "frons", ''forehead''. The former North American (''S. a. antillarum'') and Red Sea ''S. a. saundersi'' subspecies are now considered to be separate species, the least tern (''Sternula antillarum'') and Saunders's tern (''Sternula saundersi''). This bird breeds on the coasts and inland waterways of temperate and tropical Europe and Asia. It is strongly migratory, wintering in the subtropical and tropical oceans as far south as South Africa and Australia. There are three subspecies, the nominate ''albifrons'' occurring in Europe to North Africa and western Asia; ''guineae'' of western and central Africa; and ''sinensis'' of East Asia (SE Russia to Japan, SE Asia, Philippines) and the nort ...

Tern
Terns are seabirds in the family Laridae that have a worldwide distribution and are normally found near the sea, rivers, or wetlands. Terns are treated as a subgroup of the family Laridae which includes gulls and skimmers and consists of eleven genera. They are slender, lightly built birds with long, forked tails, narrow wings, long bills, and relatively short legs. Most species are pale grey above and white below, with a contrasting black cap to the head, but the marsh terns, the Inca tern, and some noddies have dark plumage for at least part of the year. The sexes are identical in appearance, but young birds are readily distinguishable from adults. Terns have a non-breeding plumage, which usually involves a white forehead and much-reduced black cap. Terns are long-lived birds and are relatively free from natural predators and parasites; most species are declining in numbers due directly or indirectly to human activities, including habitat loss, pollution, disturbance, an ...

Saunders's Tern
Saunders's tern (''Sternula saundersi''), sometimes known as the Black-Shafted tern, is a species of bird in the family Laridae. It is sparsely resident along the shores of the north-western Indian Ocean (namely southern Somalia, Arabian peninsula, Socotra, Pakistan, Andaman and Nicobar Islands and northern Sri Lanka). It is a close relative of the Little Tern, Least Tern, Yellow-billed tern, and Peruvian tern. In non-breeding plumages, the Saunder's Tern and the Little Tern may be almost indistinguishable. The two have been considered by some to be conspecific. Description Saunders's tern shares many of the features of its close relative, the Little Tern, including a white body, a black-tipped yellow bill, and a black cap with a white forehead patch. In its breeding plumage, it distinguishes itself with a straight-bordered forehead patch, possessing more black outer primaries, and duskier colored legs and feet in comparison to the bright yellow legs of the Little Tern.
