Sandwich Tern
Lat : Sterna sandvicensis
Tur : Karagagalı Sumru

Behaviour
This species breeds in very dense colonies on coasts and islands, and exceptionally inland on suitable large freshwater lakes close to the coast. It nests in a ground scrape and lays one to three eggs. Unlike some of the smaller white terns, it is not very aggressive toward potential predators, relying on the sheer density of the nests—often only 20–30 cm (8–12 in) apart— and nesting close to other more aggressive species such as Arctic Terns and Black-headed Gulls to avoid predation.
Like all Thalasseus terns, the Sandwich Tern feeds by plunge-diving for fish, almost invariably from the sea. 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.

Status
The Sandwich Tern has an extensive global range estimated at 100,000–1,000,000 million square kilometres km². (0.04–0.38 million square miles). It has a population estimated at 460,000–500,000 individuals. Population trends have not been quantified, but the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e., declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as Least Concern.[1]
The Sandwich Tern is among the taxa to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies.[5] Parties to the Agreement are required to engage in a wide range of conservation actions which are describes in a detailed action plan. This plan should address key issues such as species and habitat conservation, management of human activities, research, education, and implementation.[6]
