I am not sure if this is an Arctic or Common Tern
Can anyone help?

The tern was going for small fish. This dive ended with no result..

Info:
Terns are seabirds in the family Sternidae, previously considered a subfamily Sterninae of the gull family Laridae. They are less closely related to the waders, auks and skimmers. They have a worldwide distribution.

Most terns belong to the large genus Sterna, with the other genera being small, though some authorities split the genus Sterna into several smaller genera (see list, below).

Many terns breeding in temperate zones are long-distance migrants, and the Arctic Tern probably sees more daylight than any other creature, since it migrates from its northern breeding grounds to Antarctic waters. One Arctic Tern, ringed as a chick (not yet able to fly) on the Farne Islands off the Northumberland coast in eastern Britain in summer 1982, reached Melbourne, Australia in October 1982, a sea journey of over 22,000 km (14,000 miles) in just three months from fledging - an average of over 240 km per day, and one of the longest journeys ever recorded for a bird.

They are in general medium to large birds, typically with grey or white plumage, often with black markings on the head. They have longish bills and webbed feet. They are lighter bodied and more streamlined than gulls, and look elegant in flight with long tails and long narrow wings. Terns in the genus Sterna have deeply forked tails, those in Chlidonias and Larosterna shallowly forked tails, while the noddies (genera Anous, Procelsterna, Gygis) have unusual 'notched wedge' shaped tails, the longest tail feathers being the middle-outer, not the central nor the outermost.

Most terns (Sterna and the noddies) hunt fish by diving, often hovering first, but the marsh terns (Chlidonias) pick insects of the surface of fresh water. Terns only glide infrequently; a few species, notably Sooty Tern, will soar high above the sea. Apart from bathing, they only rarely swim, despite having webbed feet.

Terns are generally long-lived birds, with several species now known to live in excess of 25-30 years.

Hello Shir
Technically the quality of the shot is poor, but I am pleased you have shared it with us as the subject matter is great and so was your timing. Better luck next time. 2 points for the diving tern!

Well done for getting the bird 'just about' in focus. I tried following one of these and not a single shot came out acceptable, out of about 50. I think I would have rotated thwe picture to level the horizon before posting, though.
I think that the Arctic Tern and Common Tern are the same species, so it is both!

Nice shot! Thank you Shir!
