Why jet lag throws even foraging seabirds off course

Oxford study shows Manx shearwaters lose direction when their body clocks get out of sync Seabirds returning from foraging trips can be thrown hundreds of miles off course by a form of jet lag that arises when their body clocks get out of sync with local time, researchers say. Tracking data from Manx shearwaters on the west coast of the UK revealed that when the birds returned home to their colonies after trips over the Atlantic, their rapid eastward flights disrupted their sense of time and navigation.
