To power the journey, a satellite-tagged bar-tailed godwit builds massive fat reserves before departure and even shrink some internal organs during flight to reduce weight and energy use,an extreme adaptation for long distance migration across the Pacific.

      Wait, so they don’t even land in the ocean to rest? I always assumed that was part of the migration.

      “Shrink some internal organs during flight to reduce weight” sorry but that requires quite an explanation, anyone?

      So the pic of the bird is pre-flight?

      What do they do once they arrive? Just collapse for a while and take some time to properly refuel?

      So what, we can do the same thing. It only requires a $100M dollar machine and thousands of dollars worth of fossil fuels. /s

      Key Facts About the Record Flight:

      Distance: Over 13,500 km (approx. 8,400 miles).

      Time: 11 days, 1 hour (non-stop).

      Species: Bar-tailed Godwit (Limosa lapponica).

      Route: From Alaska to Ansons Bay, Tasmania, Australia.

      Adaptations: To prepare, godwits build massive fat reserves and can shrink their internal organs (gizzards, kidneys, liver) to reduce weight.

      Physiological Cost: They likely lost half their body weight during the journey.

    6. So do they have a loooong sleep once they arrive? How often do such birds need an actual sleep period?

      So how did they discover Tasmania? Did one of them one day just go “fuck it imma fly that way for a couple of weeks”?
