Arctic terns may be considered seabirds, but they don’t spend very much time on the ground. In a single year an arctic tern may fly over 44,000 miles, an amazing but necessary feat for a bird that spends its summers and winters on opposite ends of the earth. Arctic terns may fly over 1.5 million miles in their 20+ year lifetimes.
Arctic terns are primarily carnivores and feed most often on small varieties of fish such as herring and cod, usually diving down to the surface to snatch the fish out of the water. In addition, they will also feed on crustaceans, berries and insects during the northern summer.
