Most terns hunt fish by diving, often hovering first, and the particular approach technique used can help to distinguish similar species at a distance. [55] Sea terns often hunt in association with porpoises or predatory fish, such as bluefish, tuna or bonitos, since these large marine animals drive the prey to the surface. Sooty terns feed at ...

Juvenile gull-billed terns have a fainter mask, but otherwise look much like winter adults. Juvenile Sandwich terns have a short bill, and are frequently mistaken for gull-billed tern where the latter species is uncommon, such as North Sea coasts.
Juvenile lesser crested terns resemble same-age Sandwich terns, but with a yellow-orange bill, and paler overall, with only faint dark crescents on the mantle feathers. There are two other orange-billed terns within the range of this species, royal tern and Greater crested tern. Both are much larger and stouter-billed; royal also has a white ...
The greater crested tern [3] (Thalasseus bergii), also called crested tern, swift tern, or great crested tern, is a tern in the family Laridae that nests in dense colonies on coastlines and islands in the tropical and subtropical Old World.
Sterna striata in flight with tiny fish in its beak. The white-fronted tern is an average-sized tern; its dimensions are 35–43 cm (14–17 in) in length, with a wingspan between 79 and 82 cm (31 and 32 in); the male weighs on average 130 g (4.6 oz). [3]
The white tern or common white tern (Gygis alba) is a small seabird found across the tropical oceans of the world. [2] It is sometimes known as the fairy tern, although this name is potentially confusing as it is also the common name of Sternula nereis.
It has very marine habits compared to most terns; sooty terns are generally found inland only after severe storms. The Field Museum, for example, has a male specimen which was found exhausted on August 2, 1933 on the slopes of Mount Cameroon above Buea, about 1,000 m (3,300 ft) ASL, after foul weather had hit the Gulf of Guinea.
