💡Bar-tailed godwits are extraordinary migrants. They prepare by gorging on food to build massive fat reserves (sometimes doubling their body weight), then undergo physiological changes like shrinking internal organs to lighten the load and reduce energy needs. They can even "sleep" with one half of their brain at a time while flying. They navigate using Earth's magnetic field, stars, and other cues across the open Pacific with no land in sight.
This juvenile bar-tailed godwit (tagged "B6") that set the world record for the longest non-stop flight by any bird (or animal) in October 2022 , migrated from Alaska to Tasmania, Australia. It flew approximately 13,560 km (8,425 miles) in about 11 days without landing, eating, drinking, or resting. This surpassed previous records set by other bar-tailed godwits (e.g., one in 2021 flew ~12,000-13,000 km).
This is officially recognized by Guinness World Records as the longest non-stop migration by a bird.👌
