Terns are a group of seabirds that are found in all parts of the world, from the Arctic to the Antarctic. They are well-known for their graceful, buoyant flights and for their unique breeding behaviour.
Although there are over 40 species of terns, they all share certain characteristics such as their long, slender wings, their webbed feet, and their long, slender bills.
Terns are highly adapted for life at sea and have many features that help them to survive and thrive in the harsh ocean environment.
1. Common Tern
The Common Tern is a seabird in the Laridae family, found all over Europe, Asia and North America. It has a migratory nature, spending its winters in coastal tropical and subtropical regions.
Breeding adults have light grey upperparts with white to very light grey underparts featuring an orange-red beak and black cap.
They are known for their graceful flight as they hunt small fish or insects by diving into water from great heights.
During breeding season they build nests together on islands or sandbars using grasses and other materials to create them.
The female will lay two eggs which she incubates while her mate stands guard nearby; both parents take turns feeding the chicks until it’s time for them fly away.Scientific classification:

36. Iceland Gull
The Iceland Gull is a medium-sized, Arctic-dwelling gull whose range includes Canada and Greenland, but not its namesake.
Its gray wings are marked with black primaries and white tips on the inner secondary feathers which distinguishes it from other similar species like Larus hyperboreus which has completely white secondaries.
It feeds mainly by scavenging or kleptoparasitism – stealing food from other birds – as well as actively pursuing smaller prey such as crustaceans and insects in shallow waters near shorelines.
When breeding season arrives they nest atop rocky outcrops found along coastal areas to provide adequate protection against predators while also giving them an unobstructed view of their surroundings for when danger approaches.
The Iceland Gull can be seen during winter months visiting places like Iceland where temperatures remain more hospitable than its native habitat further north despite the cold weather.Scientific classification:
