No one is really sure why flamingos stand on one leg. Scientist aren't even sure why flamingos stand on one leg. But one thing that has been proposed is that flamingos stand on one leg to relieve the pressure off the one side and res that side while the other side functions and controls the body. Then when that side has rested then they will alternate legs and do the same thing until they are fully rested and ready to go on about their business.
yes, that is not unusual
resting on only one leg is a sign they are comfortable. however, if they favor one leg over the other that could be a sign of a health problem.
to pull a scale you stand on one leg (normally you stand on your right leg) then you grab the right side of your left ankle and pull it up.
the same reson we stand on two feet; It's more comfortable this way.
put one leg in front and the other in the back
