- So in between meals, apparently, frigatebirds soar ... and soar ... and soar.
In one case, for two months — continuously aloft.
This is brilliant. But, That's an interesting qualifier because I'm not sure what it means or if it's true. There are geese and vultures (!) that reach twice that height. But they're over land, and potentially not more than 12000 feet above the ground? No, I don't believe it. Most of these examples involve Everest, but what about that Swan in Ireland? Anyway, interesting. Sent on to my birdwatching-enthusiast friends."There is no other bird flying so high relative to the sea surface," he says.
In the gliding (the planes without engines) world, those heat updrafts are called thermals. If ya look around and see birds moving in circles without wings flapping, there you have a thermal! Those are rough to navigate and sorta turbulent when you're in it. Takes real effort. Neat story and analogy. 'grats!
Congratulations! This year seems to be the 1000 days year for many users.
