AI Summary

A new study published in Science examined Manx shearwaters, seabirds that travel hundreds of kilometres each day across the North Atlantic. Researchers found that the birds experience jet lag when they cross multiple time zones during their long flights. Because the birds rely on the Sun for navigation, this self‑induced jet lag alters their internal clock and produces a measurable skew in their compass orientation. The findings reveal that jet lag is not limited to humans but can affect avian navigation as well.
