Why are some flamingos white?
Moreover, do blue flamingos really exist?
No, blue flamingos do not exist. Information about blue flamingos is a humorous hoax, and the photos of blue flamingos are created by image manipulation. Most likely, one of the first sources of false information about blue flamingos is this site, presenting the “South American Blue Flamingo.”
Keeping this in consideration, why are flamingos different colors?
Flamingo feathers obtain their wonderful rosy pink color from pigments in the organisms they eat. The flamingos' feathers, legs, and face are colored by their diet, which is rich in alpha and beta carotenoid pigments. The same effect is seen when shrimp change color during cooking.
Flamingos are tough as hell. With their gangly legs, beady eyes and misshapen beaks, flamingos can come across as comical and wimpy but they're actually incredibly spunky. The blue-green algae are dangerous for most animals but the flamingos can ingest huge amounts without any problems.
