During breeding season, several thousand flamingos can get involved simultaneously with ritualized postures and movements to synchronize breeding. Their offspring are all grey at birth but later turn pink because of the pink pigment in the shrimp and crustaceans that they eat.
Through slow-motion photography, researchers discovered that these birds pump water through their bills 20 times a second to filter their food which consist of algae, crustaceans and small fish.
Now, pink plastic flamingos are one of the most famous lawn ornaments in the USA. It’s inventor Don Featherstone has even won an Ig Nobel Prize for it in 1996. It is said that there are now more plastic flamingos than there are real ones.
