The first migrating Arctic tern of the season have been spotted in Blönduós, north Iceland, arriving 4 to 5 days later than usual, the Morgunblaðið online edition reports. The tern, which travels all the way from Antarctica, is ubiquitous in Iceland in summer and nests in large groups. It can become highly aggressive during nesting season, diving and pecking the heads of unsuspecting trespassers.
