A bird completes a record flight of 13,560 km non-stop


A red godwit born in 2022 flew 11 days and 11 nights between Alaska and Tasmania last October without taking a break to eat or drink.

This bird has earned a place in history.

A five-month-old Bar-tailed Godwit traveled 13,560 kilometers from Alaska to the Australian state of Tasmania without stopping to feed or rest.

This non-stop crossing of the Pacific Ocean is considered the longest ever made by a migrating bird.

It was made official by the Guinness Book of Records.

It was thanks to a 5G satellite tag attached to its lower back that scientists were able to record this journey, which began on October 13, 2022. It lasted eleven days and an hour without the bird landing once, explains the English work.

The distance covered is equivalent to two and a half journeys between London and New York, or one third of the total circumference of the planet


All red godwits make long migrations, but those from Alaska make exceptional flights

,” ornithologist Maxime Zucca told Franceinfo.

These godwits that nest in Alaska are used to making a direct flight of 12,000 km to the Yucatán delta, in the Gulf of Mexico, where they store their fat.

To then reach New Zealand, where they spend the winter.

But "

this is the first time that one of them has won Tasmania

", rejoices Maxime Zucca on his Twitter account.

If this bird known by its tag number “


” has not made a stopover to rest, “

it is assumed that it is capable of having unihemispheric sleep phases

”, continues the ornithologist.

In birds, this type of sleep mobilizes only half of the brain and allows the other to continue flapping its wings.
