Arctic tern
Laridae
Sterna paradisaea · Least concern
The Arctic tern makes the longest migrations known in the animal kingdom, flying from the Arctic to the Antarctic and back each year: about 70,900 km for birds nesting in Iceland and Greenland. Over a lifetime that adds up to some 2.4 million km, more than three return trips to the Moon.

Black-headed gull
Laridae
Chroicocephalus ridibundus · Least concern
Black-headed gull parents remove the eggshells from the nest once the chicks hatch, a habit that helps keep the nest hidden from predators. These gulls are long-lived, with a wild bird reaching at least 32.9 years, and number 2 to 3 million pairs worldwide.

Black tern
Laridae
Chlidonias niger · Least concern
Draining its marshes wiped out the black tern's English breeding population around 1840. Since then the bird has tried again and again to return, with only a handful of nests recorded in England, and one in Ireland, in the second half of the 20th century.
