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 north and east coasts of Australia and New Guinea

The little tern breeds in colonies on gravel or shingle coasts and islands. It lays two to four eggs on the ground. Like all white terns, it is defensive of its nest and young and will attack intruders.

Like most other white terns, the little tern feeds by plunge-diving for fish, usually from saline environments. The offering of fish by the male to the female is part of the courtship display.

This is a small tern, 21–25 cm long with a 41–47 cm wingspan. It is not likely to be confused with other species, apart from fairy tern and Saunders's tern, because of its size and white forehead in breeding plumage. Its thin sharp bill is yellow with a black tip and its legs are also yellow. In winter, the forehead is more extensively white, the bill is black and the legs duller. The call is a loud and distinctive creaking noise.

The little tern was described by the German naturalist Peter Simon Pallas in 1764 and given the binomial name Sterna albifrons.

The Little Tern, Sternula albifrons, is a diminutive member of the seabird family Laridae. This sprightly bird is easily recognized by its compact body, measuring 21–25 cm in length with a wingspan of 41–47 cm. It is characterized by its white forehead, which is particularly prominent during the breeding season.

When observing the Little Tern, look for its yellow, thin, sharp bill tipped with black, and its matching yellow legs. In breeding plumage, the white forehead contrasts with a black cap, while in winter, the forehead becomes more extensively white, the bill turns black, and the legs appear duller. Its flight is buoyant and graceful, a delight to watch as it hovers over water before diving.

This species is partial to coastal environments, favoring gravel or shingle beaches and islands for breeding. It also frequents inland waterways, adapting to the habitats provided by temperate and tropical regions alike.

The Little Tern is a globe-trotter, breeding across temperate and tropical Europe and Asia, and migrating to subtropical and tropical oceans for the winter. Its range extends as far south as South Africa and Australia, with three recognized subspecies occupying distinct geographical areas.

The Little Tern is a colonial nester, laying two to four eggs directly on the ground. It is fiercely protective of its nest and offspring, ready to dive at intruders with surprising ferocity. Courtship involves the male presenting fish to the female, a tender ritual that strengthens their pair bond.

Listen for a loud, distinctive creaking noise that carries over the sounds of the sea, a call that is unmistakably that of the Little Tern.

Breeding colonies are established on coasts and islands, where the Little Tern's nest can be found on the bare ground. The commitment to their young is evident in their vigilant defense against potential threats.

Adept at plunge-diving, the Little Tern primarily feeds on fish from saline environments. Its hunting technique is a marvel of precision, as it drops from the air into the water to catch its prey.

The Little Tern is currently listed as Least Concern by the IUCN. However, its populations have faced declines due to habitat loss, pollution, and human disturbance, particularly in coastal areas and along European rivers where traditional habitats have been compromised. Conservation efforts are ongoing to protect this species and its habitats, especially along rivers like the Drava where populations are critically threatened. The Little Tern is also a subject of the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA), highlighting the international commitment to its preservation.
