Like most terns, the Arctic tern has high aspect ratio wings and a tail with a deep fork. [19] The adult plumage is grey above, with a black nape and crown and white cheeks. The upperwings are pale grey, with the area near the wingtip being translucent. The tail is white, and the underparts pale grey. Both sexes are similar in appearance.
The arctic tern is K-selected, caring for and aggressively defending a small number of young. Parents feed them fish for a considerable time, and help them fly south to winter. Arctic terns are long-lived birds, with many reaching twenty years of age. They eat mainly fish and small marine invertebrates. The species has an estimated one million ...
This is the longest regular migration by any known animal. Arctic terns are medium-sized birds with mainly grey and white plumage, a red beak and feet, and a deeply forked tail. The arctic tern is K-selected, caring for and aggressively defending a small number of young. They eat mainly fish and small marine invertebrates.
the Arctic and sub-Arctic regions of Europe, Asia, and North America (as far south as Brittany and Massachusetts). River tern: Sterna aurantia: inland rivers from Iran east into the Indian Subcontinent and further to Myanmar to Thailand Black-bellied tern: Sterna acuticauda: Pakistan, Nepal, India and Bangladesh, with a separate range in ...
Terns are generally long-lived birds, with individuals typically returning for 7–10 breeding seasons. Maximum known ages include 34 for an Arctic tern and 32 for a sooty. Although several other species are known to live in captivity for up to 20 years, their greatest recorded ages are underestimates because the birds can outlive their rings. [5]
Laridae is a family of seabirds in the order Charadriiformes that includes the gulls, terns (including white terns), noddies, and skimmers. It includes around 100 species arranged into 22 genera . They are an adaptable group of mostly aerial birds found worldwide.
The Antarctic tern does not migrate like the Arctic tern does, but it can still be found on a very large range. This tern species is actually more closely related to the South American tern. [2] Gulls, skuas and jaegers are the primary predators of the bird's eggs and young. The Antarctic tern can be further divided into six subspecies.
Arctic terns breed in the arctic and subarctic and winter in Antarctica. Like many birds, seabirds often migrate after the breeding season . Of these, the trip taken by the Arctic tern is the farthest of any bird, crossing the equator in order to spend the Austral summer in Antarctica.
