Which bird holds the record for the longest migration distance, and how far does it travel?
The bird species that holds the record for the longest migration distance is the Arctic Tern (Sterna paradisaea). These birds breed in the Arctic regions during the summer and then migrate to the Antarctic region for the winter, traveling a round trip distance of up to 44,000 miles (71,000 kilometers) each year. This incredible journey takes them across the entire planet, from one polar region to the other, and covers more distance than any other bird species. The Arctic Tern's migration is made possible by its ability to fly long distances without stopping, its efficient use of energy, and its ability to navigate using the Earth's magnetic field and other environmental cues.
