First time and possibly last time visitor to this subreddit. I'm looking to learn about this one fact among a space of people who would probably love to talk my ear off about this. I saw an IG post that said a Sooty Tern can stay airborne for YEARS, and only land to mate.

Soooo many questions. First of all, how do they eat and sleep? Don't their muscles get tired?What exactly are the mechanics and evolutionary advantage of this? Other facts that would be cool to know?

I have a bachelor's in Biology, so I can understand concepts on an undergraduate level at least. Please give me the info dump. My mind is blown :)
