If you think your commute is too long, be glad you’re not a godwit.Each year around this time, tens of thousands of bar-tailed godwits migrate from Alaska to New Zealand and Australia. The 7,000-mile journey — the longest nonstop migration of any land bird — is completed in eight to 10 days of continuous flapping without stopping to eat, drink or rest.
The godwit’s ordeal is so extreme that, as one recent paper put it, it challenges “underlying assumptions of bird physiology.” Before the bird takes off, its organs shrink, its pectoral muscles grow, and it gobbles up insects, worms and mollusks to store fat for the long journey. One scientist called the godwits “obese super athletes.”
