Flamingos are not naturally pink. In fact, they are grey! The pinkish tint in their feathers is caused by the food they eat. Their diet includes brine shrimp and blue-green algae.
The high levels of the natural dye, canthaxanthin turns those grey feathers pink! You may know that the same thing happens when you boil shrimp it goes from grey to pink! Don’t worry, though, eating shrimps won’t turn you pink!
The colour of flamingos definitely makes them more attractive in zoos and wildlife centres. Their elegant necks have a slight orange tint that reminds you of a sunset.
Flamingos are beautiful animals even without their pink colour but you have to admit it is a bonus!
