The Arctic tern flies a round trip of 21,750 miles a year, breeding in the Arctic in the northern summer and feeding in the Antarctic during the southern summer. The bar-tailed godwit migrates farther in a single trip than any other bird. Each year it travels non-stop from Alaska to New Zealand in nine days and loses over half its body weight.<|im_end|>
