Oxford study shows Manx shearwaters get lost 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.

Part detective story, part cutting-edge science, Mindlin’s mission leads him to the dusty 1960s archives of Buenos Aires naturalist, confirming that some songs no longer echo in the biosphere. So he deploys “robot tutors” to see whether young birds can learn and spread the old songs once again.
