The first Arctic Terns were seen in Selfoss yesterday. A few days ago they were seen at the coast. The Tern is known as one of the longest distance migrant. It is an agile flyer and is on constant flight over sea except during the breeding time in the Arctic. Its winter grounds, if you can call it that, are in the sea around South Africa and Antarctica.

The Tern is a breeding bird in Iceland, mostly staying  near the coast but also inland, even as far as the interior. The Icelandic breeding population is estimated around 500,000 pairs.
