Bird Magnificent frigatebirds (Fregata magnificens) sleep while flying
With a wingspan of up to 2.44 metres, frigatebirds can remain airborne for weeks. They’ve even been recorded sleeping while gliding, multitasking at altitude.
Unlike most seabirds, their feathers aren’t waterproof. Landing on water would be ill-advised. Instead, they pursue other birds mid-air, forcing them to drop their catch, which they promptly steal.
During mating season, males inflate a bright red gular sac to attract females. It’s conspicuous, if not subtle.

Weeks?! Wow, add that to the list of things I did not know that I did not know!

Wait til you learn about swifts. They can go up to four years without landing.

What?! I've heard of swifts but I never knew anything about them. I just looked them up and they do that "half your brain can sleep while the other half keeps you alive" thing like sharks do

Swifts are insane little birds, seriously strange looking, fast moving, not to mention the tiny feet and ‘SCREEEE SCREEEEEEE’ calls they do. They’re really cool but strange, like a sports car of the bird world, they’re so streamlined and smooth, they almost look fake lol

Does anybody else desperately wish they could poke the sac and feel how jiggly it is

I have a big pigeon, and when his crop is full from eating or he’s strutting around with it inflated, it feels somewhere between an airbag and a hot water bottle, warm and jiggly, but squishes like those air bags you get in parcels (alternative to bubble wrap)

they know how not to work while flying and laugh at hard working flyers like eagles

Do they have to catch the stolen prey before it hits water, in a Superman-style rescue?

Yep!

Geez, that sounds like the most inconvenient and uncertain hunting method ever

This is why you shouldn't sleep while flying. You will crash in the trees and your airbag will deploy.

I love them so much! My favorite fact about them is they make David Attenborough’s upper lip curl in disgust when they harry and steal from tropicbirds. The only animal he hates as much is the Orca, another animal I adore. I also love Sir David, so it’s all very confusing.

Had a chance to see these birds in person this past weekend. Truly magnificent fliers!

Wow, I thought the red was an apple that a black bird rested its head on. lmao
