[Note Guidelines] Photographer's Note
Another new bird for me on Iceland was the Arctic Tern. There are several colonies. In this time of the year they have a lot of chicks walking around. My next posting wil be an Arctic Tern chick.
This one was not happy with my presence. He was attacking me, so I left him alone soon.

The Arctic Tern (Sterna paradisaea) is a seabird of the tern family Sternidae. This bird has a circumpolar breeding distribution covering the Arctic and sub-Arctic regions of Europe, Asia, and North America (as far south as Brittany and Massachusetts). The species is strongly migratory, seeing two summers each year as it migrates from its northern breeding grounds along a winding route to the oceans around Antarctica and back, a round trip of about 70,900 km each year. This is by far the longest regular migration by any known animal. The Arctic Tern flies as well as glides through the air, performing almost all of its tasks in the air. It nests once every one to three years (depending on its mating cycle); once it has finished nesting it takes to the sky for another long southern migration.

Arctic Terns are medium-sized birds. They have a length of 33–39 cm and a wingspan of 76–85 cm. They are mainly grey and white plumaged, with a red beak (as long as the head, straight, with pronounced gonys) and feet, white forehead, a black nape and crown (streaked white), and white cheeks. The grey mantle is 305 mm, and the scapulae are fringed brown, some tipped white. The upper wing is grey with a white leading edge, and the collar is completely white, as is the rump. The deeply forked tail is whitish, with grey outer webs. The hindcrown to the ear-coverts is black.

Arctic Terns are long-lived birds, with many reaching thirty years of age. They eat mainly fish and small marine invertebrates. The species is abundant, with an estimated one million individuals. While the trend in the number of individuals in the species as a whole is not known, exploitation in the past has reduced this bird's numbers in the southern reaches of its range.

Distribution and migration
The Arctic Tern has a worldwide, circumpolar breeding distribution which is continuous; there are no recognized subspecies. It can be found in coastal regions in cooler temperate parts of North America and Eurasia during the northern summer. While wintering during the southern summer, it can be found at sea, reaching the northern edge of the Antarctic ice.
The Arctic Tern is famous for its migration; it flies from its Arctic breeding grounds to the Antarctic and back again each year. This 19,000 km journey each way ensures that this bird sees two summers per year and more daylight than any other creature on the planet. One example of this bird's remarkable long-distance flying abilities involves an Arctic Tern ringed as an unfledged chick on the Farne Islands, Northumberland, UK, in the northern summer of 1982, which reached Melbourne, Australia, in October 1982, a sea journey of over 22,000 km in just three months from fledging. Another example is that of a chick ringed in Labrador, Canada, on 23 July 1928. It was found in South Africa four months later.

Research using tracking devices attached to the birds was published in January 2010 and showed that the above examples are in fact not unusual for the species; eleven Arctic Terns that bred in Greenland or Iceland each covered 70,900 km on average in a year, with a maximum of 81,600 km. The difference from previous estimates was because the birds were found to take a meandering course to take advantage of prevailing winds. The average Arctic Tern lives about twenty years, and will travel about 2.4 million km.
Arctic Terns usually migrate far offshore. Consequently, they are rarely seen from land outside the breeding season.

Aggressive behaviour from a Tern, Peter? Must be worried about the safely of its chicks.
Very sharp in-flight picture at average shutter speed.
The posture of the bird with its head down is quite interesting.
Thanks for another great image from Iceland.

Fine composition, subtle colours to show the flight of this elegant bird. Ideal blurred background as contrast to the white plumage of the Arctic Tern. Beautiful picture.
