Science Study: Manx Shearwaters Show Jet Lag-Like Navigation Errors on Atlantic Flights

1.7 · 1d ago · WORLD · TECH

The Facts

  • A study published in the journal Science found that Manx shearwaters appear to become slightly disoriented on long flights across the Atlantic, with the authors attributing this to the birds' internal clock falling out of sync with the sun's position. NPR only
  • Lead researcher Patrick Lewin, a behavioral ecologist at the University of Oxford, used GPS tracking data collected by colleagues over 20 years on shearwater flights out to the Atlantic and back. NPR only
  • Returning birds veered slightly off course; the maximum deviation observed was seven degrees, which added about three miles to a 600-mile journey. NPR only
  • Manx shearwaters are believed to navigate using the sun as a compass, which requires knowing the time of day. NPR only
  • Shearwaters mate for life and lay one egg; partners take turns incubating while the other forages at sea for up to two weeks, often returning to the colony in about a day. NPR only

  • Alice Boyle, a biologist at Western University's Centre for Animals on the Move who was not part of the study, called the paper 'so cool' and said studies showing navigation decisions in action are rare. NPR only

Context

Researchers report that Manx shearwaters, seabirds common in the British Isles and closely related to albatrosses, show small navigation errors consistent with jet lag. The findings, published in Science, draw on two decades of GPS tracking data.

The birds are believed to use the sun as a compass, so a mismatch between their internal clock and the sun's position would produce small heading errors. The observed deviations were small, at most seven degrees.

Independent AI personas each scored importance 1–10; the story's score is a trimmed mean (highest and lowest votes dropped). Vote spread: 1.

2 News Editor This is a niche wildlife science study reporting a small, observational finding about seabird navigation with minimal direct impact on people, though it is a concrete published result rather than mere commentary.
2 Informed Citizen This is a niche wildlife science study about seabird navigation with negligible direct impact on ordinary people and little relevance in a week.
1 Business Analyst This is a niche wildlife science study with tiny navigation deviations and no economic or market-relevant impact.
