Why are flamingos pink?

Flamingos are pink because of their diet, which is high in beta carotine. http://en.wikipedia.org/wiki/Flamingo

They’re pink so that we could have tacky plastic pink flamingos. Can you imagine how silly we’d seem if we had plastic pink flamingos when real flamingos were, say, brown?

so we can flock yards with plastic pink flamingos to raise money during breast cancer month

Flamingos are pink? Wait Are those the birds or the dancers?

they eat pink wafers!!

The food flamingos eat that contain the carotenoid pigments (like beta-carotene in carrots and lycopene in watermelon) are the blue-green algae and small crustaceans who eat algae.
