Hi there. I'm no ornithologist, but I have done a reasonably comprehensive journal and web search on this topic for you. I haven't found anything about swan leg raising, and I don't know enough about swan behaviour to make a call on this one. Try searching some of the respected bird journals and see if swan thermoregulatory behaviour has been well documented. The Flamingo was a little easier to find info on! Both these websites have similar information on flamingo thermoregulation: www.naturezoo.com/birds/greaterflamingo.html www.seaworld.org/flamingos/fadapt.html > "Curling one leg under their body helps keep the foot warm and conserves body heat. They will stand on one leg in both cool and warm environments." There you go! Apparently leg curling is typical flamingo behaviour!
