Cartagena_massed_flamingos_4232

Cartagena, Colombia:

A “zoo” near the cruise-ship dock featured a couple dozen flamingos. No one knows for sure why flamingos rest on one leg; it might have to do with avoiding muscle fatigue or not losing body heat through their bare legs. No one knows for sure why flamingos favor one leg over the other, either. But research shows the choice is influenced by the majority behavior of the flock.
