Chris,
Too LITTLE oxygen is toxic, and to little babies too much can be, to their retinas.

But in coming down from Cloudbait, have you considered the nitrogen? Divers breathing air who go below 100ft (30m) start to experience 'nitrogen narcosis' as the partial pressure of nitrogen in air rises to about 2400mmHg. Experiments have been done at sea level to wash out as much nitrogen as possible by breathing pure oxygen that showed a marginal increase in cognition. So your confusion on descending from your eyrie is due to the nitrogen!
John
Too much oxygen is toxic to everyone. (But of course, I was just joking about the amount of oxygen at sea level being a problem.)

But maybe the nitrogen explains my painful joints when I drive back to altitude too fast!
Chris

<<The mountain gorilla inhabits the Albertine Rift montane cloud forests and of the Virunga Volcanoes, ranging in altitude from 2,200–4,300 metres. Most are found on the slopes of three of the dormant volcanoes: Karisimbi, Mikeno, and Visoke. For reasons unknown, mountain gorillas that have been studied appear to [have a PHOBia] of certain reptiles and insects. Infants, whose natural behavior is to chase anything that moves, will go out of their way to avoid chameleons and caterpillars. They also [have a PHOBia] of water and will cross streams only if they can do so without getting wet, such as by crossing over fallen logs. The mountain gorilla's dislike of rain has been observed and noted, as well. Mountain gorillas are descendants of ancestral monkeys and apes found in Africa and Arabia during the start of the Oligocene epoch (34-24 million years ago). It was about 9 million years ago that the group of primates that were to evolve into gorillas split from their common ancestor with humans and chimps; this is when the genus Gorilla emerged. Mountain gorillas have been isolated from eastern lowland gorillas for about 400,000 years and these two taxa separated from their western counterparts approximately 2 million years ago.>>

No Shout, Sherlock! What other animal LIKES rain, except perhaps. ducks? Ordinary garden birds shelter in heavy rain. Have you ever seen a wet buzzard? Or a vulture?

As PG Wodehouse nearly said, it is not hard to distinguish a wet vulture from a ray of sunshine.

To be surprised that intelligent, insightful creatures like gorillas avoid getting wet is just humans, patronising!

Lots of animals (including humans) seem just fine with rain, and don't typically take shelter. (Humans, of course, usually bring portable shelter with them.)
