Have to say, Flashy, I larfed aloud at the idea of missionaries escaping by drinking the water.

Well, thanks - but seriously, folks, it could be a question if we can come up with some science on the odd fact that we seem to be able to tolerate hotter liquids internally than externally.

Flamingos frequently stand on one leg. Curling a leg under the body keeps the foot warm and conserves body heat. Flamingos stand on one leg in both cool and warm environments.



This agrees with an article i've just read that says flamingos try and stay ready for flight at any time. In order to do this, they have to keep warm around the clock. Because their legs are long, featherless and full of blood-vessels, they radiate heat very easily. If both of them were down at one time the bird would lose too much heat and not be ready for flight. Hence the keeping one up and keeping warm.

This throws up two problems though: 1) Why do they still keep one leg up when standing in boiling temperatures, surely they wouldn't lose heat with two feet in a geyser?
2) If their legs are coursing with blood vessels then it doesn't help in the explanation of how they can withstand such hot water!

What do you do if a bird poos on your windscreen?

Hope it isn't a flamingo, since they're rather larger than most birds...

I did read a couple of websites that pointed out that all birds stand on one leg at one time or another though - it's just rather more noticeable in flamingos.

Flash - re your post 4479 - I've put an offering on the Meaning of Liff thread for it, but you are welcome to suggest a better choice of word.

Great gag, Soph, even if Flash trod on your reveal.

On, on with the factoids.

The vivid red plumage of flamingoes comes,oddly enough, from eating blue-green algae, not from eating pink shrimps.

The algae is rich in carotenoid pigments (similar to that found in carrots).

There are only two kinds of birds which feed their young with milk. One is flamingoes. The other one is pigeons.

Unlike mammals, both mother and father flamingo produce milk.

Flamingo milk is bright red.

Flamingoes who are not parents can start producing milk in captivity, stimulated by the cries of young birds.

I think flamingo 'milk' is regurgitated though, isn't it? At any rate, I wasn't aware that flamingos had nipples.
