I wonder if you (the bird) get hypoxia or altitude sickness and experience the whole thing as a sort of gliding blur

- Scoundreller 3y agoI guess they always have the choice of turning around and increasing the pressure hitting their beak? What’s the temperature like up there though? I guess it’s different during this kind of storm than usual? Internet says temperature drop 2C per 1000’
- HeyLaughingBoy 3y ago> Internet says temperature drop 2C per 1000’ The Dry Adiabatic Lapse Rate: one of only two things I retained from a Meteorology class decades ago :-)
- seabass-labrax 3y agoAnd the other fantastically unforgettable fact?
- lainga 3y agoThe saturated adiabatic lapse rate! When they meet it's happy land^W^W the cloud base
- HeyLaughingBoy 3y agoThere are 27 species of clouds. My favorite will always be cirrus spissatus cumulonimbogenitus (google helped me remember how to spell it!).
- matheusmoreira 3y agoNow I won't be able to forget that either. Clouds have species? I thought they were random. Until today.

- xenadu02 3y agoBird lungs work very differently from mammals. They have air sacs in front of and behind the lungs that take up a significant portion of their body cavity. The lungs themselves don't expand or compress. Air moves unidirectionally through the lungs both during inhalation and exhalation so there is no time at which the lungs themselves are not operating optimally. It is a two-phase system... during inhalation the posterior air sac fills with fresh air as spent air accumulates in the anterior air sac. The effective blood gas exchange surface area is about double that of mammals as well. Basically: bird lungs are "pipelined" and highly optimized to extract oxygen even at altitude.
- everybodyknows 3y agoA reminder of just how far back in genetic history birds and mammals went separate ways. Another being that birds have no X or Y chromosomes -- their genetic machinery for sex is very different from ours.
- NooneAtAll3 3y agosome birds have X and Z and 2 of the same shape in the males, while females have different
- wnoise 3y agoW and Z.
- ordu 3y agoAnd no neocortex. Smart birds like ravens rely on a traditional system of ganglia to be smart, not on that hyped six-layered neocortex covering most of the brain.
- euroderf 3y agoDo we know whether this is also a feature of dinosaur lungs ? It might make an interesting sidebar in a Jurassic Park sequel.
