Love by heart

We couldn't do a gallery of pink animals and not include the most famous pink creature of all. For our final blushing beauties, the epitome of pink: flamingos. Although when flamingoes first hatch, they are a drab grey; they develop into glorious shades of peach and coral primarily because of their diet. The red and blue-green algae they eat is chock-full of beta carotene, which contains a reddish-orange pigment, and the mollusks and crustaceans flamingos favor also possess pigment-rich carotenoids.
And if their romantic color and heart-shaped kisses weren't lovey-dovey enough, consider this: Although flamingoes group in flocks that can number in the hundreds of thousands, a flamingo picks a single mate and generally remains monogamous for life.
