Even birds get jet lagged, study shows
New research shows that humans are not the only species to get jet lag: Some birds appear to experience it too.
asserted
birds → get → it
A study published in the journal Science found that a type of seabird known as the Manx shearwater appears to become slightly disoriented during long flights across the Atlantic Ocean.
asserted
type → publish → Ocean
That disorientation, the authors say, is due to the bird's internal clock falling out of sync with the sun's position in the sky.
asserted
clock → say → sky
They look a little like seagulls, but "they're actually very closely related to an albatross," said Patrick Lewin, a behavioral ecologist at the University of Oxford.
asserted
Lewin → look → Oxford
Shearwaters mate for life, and when they breed, a couple lays just one egg.
asserted
couple → mate → egg
Then they take turns incubating it: "One partner will sit on the egg nonstop while the other one goes out to sea," Lewin said.
asserted
Lewin → take → sea
For up to two weeks the hunting partners scour the North Atlantic for fish and squid, often travelling hundreds of miles from their nests.
asserted
partners → scour → nests
Once these birds' bellies are full "they absolutely bomb it back to their colony," Lewin said.
asserted
Lewin → bomb → colony
Often they make the long journey home in just a day or so.
asserted
they → make → day
Which raised an interesting question: Do Manx shearwaters feel jet lag (or perhaps more aptly, flap lag)?
asserted
shearwaters → raise → lag
To see if these little birds really did feel the effects of flying through time zones like humans do, Lewin used a remarkable tool – for 20 years, his colleagues had been tagging birds with GPS trackers and collecting data on their flights out to the Atlantic and back.
asserted
colleagues → see → Atlantic
He figured he could see the jet lag in their flights.
uncertain
he → figure → flights
That's because the Manx shearwaters are believed to use the sun to navigate.
asserted
shearwaters → believe → sun
"To use the sun as a compass you have to know what time of day it is," Lewin said.
asserted
Lewin → use → day
If the shearwaters had the wrong time of day, they would fly the wrong way.
asserted
they → have → day
That's exactly what Lewin and his colleagues saw.
asserted
Lewin → see → what
As the birds rushed back to their partners and eggs, they veered ever-so-slightly off course.
asserted
they → rush → course
It wasn't much: A seven-degree error, the maximum deviation observed, only took a bird out of its way by about three miles on a 600-mile journey.
asserted
error → observe → journey
"It's a really small addition," he said.
asserted
he → say → ?
"This paper is so cool," said Alice Boyle, a biologist at the Centre for Animals on the Move at Western University in Ontario, Canada who was not part of the study.
asserted
who → say → study
Boyle said pretty much every creature on the planet, from corals to chipmunks, has to navigate its environment, yet it's rare to see a study showing navigation decisions in action.
asserted
it → say → action
That's what makes this type of GPS work so valuable.
asserted
type → make → work
"It's using these wild birds that travel to completely remote places and we're able to learn so much about how they do that," she said.
asserted
she → use → that
