The Sky Rivers: Bar-Tailed Godwits and Record-Breaking Flights

Join host David Hale as he explores the incredible world of bar-tailed godwits, the champion long-distance migrants of the bird world. Discover how these unassuming shorebirds accomplish the longest non-stop flights in the animal kingdom, traveling over 7,000 miles across the Pacific Ocean without landing. Learn about the remarkable physiological changes these birds undergo to prepare for their epic journeys, from doubling their body weight to shrinking their digestive organs. Explore the cutting-edge satellite tracking technology that revealed their use of 'sky rivers' – atmospheric highways of favorable winds that carry them across vast oceanic expanses. Meet E7, the record-holding female who flew non-stop from Alaska to New Zealand in just over eight days. Understand the complex navigation systems godwits use to cross thousands of miles of open ocean with pinpoint accuracy, including magnetic fields, celestial cues, and possibly infrasound. Examine the challenges these incredible migrants face from climate change and habitat loss, particularly the disappearing coastal wetlands crucial to their survival. This episode reveals how bar-tailed godwits represent one of nature's most spectacular examples of endurance, navigation, and adaptation in the face of seemingly impossible odds.
