A bar-tailed godwit completed a remarkable migration of approximately 13,560 kilometers from Alaska to Australia without stopping for food or water, setting a new world record.
In October 2022, a small bird known as the bar-tailed godwit astonished the world by completing an unprecedented migration across the globe. This bird, identified as B6, undertook a remarkable journey from the Kuskochwim Delta in Alaska to Tasmania, Australia, covering a distance of around 13,560 kilometers without a single stop for food or water. This feat has now been officially recognized in the Guinness World Records after a comprehensive three-year scientific study by experts.
Scientists from the United States Geological Survey (USGS) tracked the bird's extraordinary journey using a small solar-powered tag. This tagging allowed researchers to verify that the godwit flew continuously for 11 days, demonstrating incredible endurance as it traveled without any rest. The record highlights not only the bird's extraordinary capabilities but also attracts attention to the migration patterns of such avian species, which can traverse the globe in search of suitable habitats.
The bar-tailed godwit, despite its small size of only 300-400 grams, undergoes significant physiological changes before its migratory flight. A few weeks prior to migration, the bird feeds extensively, accumulating fat reserves that are crucial for its long journey. By significantly increasing its weight, the godwit prepares to tackle the extreme distances, showcasing an impressive evolutionary adaptation that allows it to thrive in varied environments around the world.
