Breeding in a wider range of habitats than any of its relatives, the common tern nests on any flat, poorly vegetated surface close to water, including beaches and islands, and it readily adapts to artificial substrates such as floating rafts.

A common tern’s nest is a simple scrape in the ground, often lined with small stones, shells, and vegetation to provide some insulation and camouflage. Because it’s a simple scrape nest, they can often build them in just a few days, typically 1 – 3 days.

Common Terns nest on rocky islands, barrier beaches, and saltmarshes and forage over open waters. Terns often gather over warmer waters with high densities of American sand lance (a small fish) in the spring, and tuna that help scare up smaller fish in the fall.

The Common Tern (Sterna hirundo) is Eastern Egg Rock's most numerous species, with about 1400 pairs nesting on the island. Terns are related to gulls, but have pointed wings and forked tails, allowing them to fly very gracefully.

The Common tern enjoys a wide range, but its colonies are threatened by human disturbance through increase in recreational activities, naturally fluctuating water-levels flooding their nest sites, habitat loss from coastal development, erosion, pollution and invasive vegetation at …

2024年12月10日 · The Common Tern Sterna hirundo nests colonially in both marine and freshwater habitats with incubation and chick rearing being shared parental responsibilities.

Common Terns prefer to nest on islands or in salt marshes in areas with sand, gravel, shell or rocky substrates with some scattered vegetation or other cover for sheltering chicks. Colonies are generally placed within 20 km of foraging areas that have fish available 50 cm below the water’s surface (shallow coastal waters, bays, inlets, shoals ...

Denac & Bozic give an account of a wide variety of conservation measures undertaken to provide and enhance breeding habitat for Common Terns in Slovenia, including various actions to manage vegetation, reduce predation and increase nest site availability by preventing Black-headed Gulls from occupying sites (the latter by blocking access until ...

Common Terns are a colony-nesting species. Therefore, shelters may not attract birds to an area that currently does not have nesting terns; rather, they provide shade and protection from predators for chicks on the open expanse of a beach.

Common Terns are found nesting on flat, poorly vegetated surfaces close to water, such as beaches, islands, and artificial substrates like floating rafts. They adapt to a variety of habitats, from the taiga to tropical shores, and avoid excessively rainy, windy, or icy areas.
