Great story. Amazing birds. I like to hear about super-commuters and Arctic terns are the best. Where do they get the energy to move their wings for their journeys?
“Where do they get the energy to move their wings for their journeys?”
Look at those wings. They have one of the highest wing to (light)weight ratios or whatever they call it (big wings small bird). My guess is they do a lot of soaring.
Just amazing.
