Arctic Tern Feeding

Arctic tern's diet varies depending on location and time, but is usually carnivorous. In most cases, it eats small fish or marine crustaceans. In Irish waters they feed on herring and cod, amongst other fish.

They dip down to the surface of the water to catch prey close to the surface. Arctic terns may also pick off insects in the air when breeding. They are also known to harass other birds so as to startle them into releasing their catches

Arctic Terns Nesting

Arctic Tern eggs

Arctic terns are ground-nesting and that makes them and their nests vulnerable to predation by cats and other animals. If their eggs or young come under threat these terns will aggressively attack any perceived threat. They often form mixed colonies with other terns, such as common and Sandwich terns.

In Ireland arctic terns are a coastal breeding bird, but will also breeds inland on the fresh water lakes of Lough Corrib in County Galway and on Lough Conn in County Mayo. Some of the largest Irish arctic tern colonies can be found found in Counties Wexford, Kerry, Mayo, and Donegal.

Long Distance Travellers

Arctic terns are renowned for their long-distance migrations. One tern, ringed as a chick on the Farne Islands off the coast of Northumberland, England in June 1982, turned up in Melbourne, Australia in October of the same year. As they travel over open seas (not overland) it is estimated this involved a flight of more than 20,000 Km. Most arctic terns return to the same area, even the same colony, where they were hatched to breed.
