The arctic tern (0) IS a water-loving bird that hatches during summer in the Arctic, the northernmost 1 of the Northern Hemisphere. During the unbearably cold, dark arctic winter, the arctic tern flies south, following the summer season all the way to the Antarctic 2 on the other side of the Earth. Because arctic terns do not fly in a straight line, the 3 they fly every year is even longer than the approximately 30,000-kilometer from pole to pole. This 4 the arctic tern's migration one of the longest of any animal on Earth. Like a lot of other birds, fish is 5 arctic terns eat. They catch fish by gliding 6 the ocean, then plunging their feet or beaks in the water to skim fish near the surface. Rarely, arctic terns will snatch flies or 7 insects out of the air, but they prefer fish and other marine creatures, such as shrimp. Arctic terns have beaks and webbed feet, both of 8 are almost the same shade of tomato-red. They have gray-white bodies and a head of jet-black feathers, which looks almost like a baseball cap.
