The Arctic tern has arrived in Iceland a week later than usual, according to ornithologist Jóhann Óli Hilmarsson in the South Iceland town of Stokkseyri, mbl.is reports.
The birds, which make a roundtrip of around 90,000 kms (56,000 miles) from Iceland or Greenland to their breeding grounds in Antarctica, take part in by far the longest known migration in the animal kingdom.
Arctic tern nesting has gone badly in parts of Iceland in recent years due to a lack of sandeel for the young birds.
