Why are flamingos pink? Discover the surprising science behind their color, from diet and pigments to courtship and symbolism. For flamingos, the phrase "You are what you eat" holds more truth than it might for humans.

The brilliant pink and red shades of flamingos come from pigments called carotenoids. These natural compounds are found in various plants, algae, and bacteria, and are also responsible for the orange color in carrots and red in ripe tomatoes.
