Jet lag can throw seabirds hundreds of miles off course, study finds

Seabirds can suffer a form of jet lag that sends them off course, an Oxford study of 20 years of GPS data on Manx shearwaters shows. Fast eastward flights home after Atlantic foraging trips put their body clocks behind local time, skewing their sun compass. Adults corrected quickly, but first-time foragers risk straying by hundreds of miles.
