The arctic tern is a small seabird known for its remarkable migratory journey. It breeds in the Arctic regions during the summer and travels to the Antarctic for the winter, covering about 44,000 miles each year. This long-distance migration is the longest of any bird species. Arctic terns have a distinctive appearance, with a white body, black cap on their head, and long, slender wings. They primarily feed on small fish and invertebrates, catching their prey by diving into the water. Their adaptability and endurance make them fascinating subjects for ornithologists and birdwatchers alike.
