Flamingos: Nature’s Weirdest Bird?

Learn the secret to what turns their feathers pink.

A flamingo looks like a bird cooked up by a toddler after a litre of red cordial – absurdly long legs, knobby ankles, and an outsize beak – and collared with the brightest crayon in the box.

But the sum of its physical oddities enables the Caribbean flamingo to thrive in salt pans, mudflats, tidal lagoons, and mangrove swamps.

The glorious feathers? They seem to exist purely for our delight, but in fact they are not pink at first. Chicks hatch with white feathers that turn grey – and later take their pink colour from aqueous bacteria and beta-carotene obtained from their food.

With its hooked bill it scrapes up clumps of mud to make a nest. Stiff bristles inside its bill filter water containing small crustaceans, molluscs, insects and their larvae, as well as aquatic vegetation.

Although flamingos have become a visual cliché immortalized in cheap plastic lawn ornaments, they remain strangely mysterious. “As recognizable as they are, we don’t know much about them,” says Chris Brown who studies the flamingos on Mexico’s Yucatán Peninsula.

Scientists are uncertain about even simple behaviours, like the propensity to stand on one leg. (Some postulate that it has to do with the way the birds rest.)

And because flamingos live in such remote areas and pick up and move as feeding grounds flood or dry out, researchers have a hard time counting and tracking them – learning how they may be affected by drought, hurricanes, and fluctuating water levels due to climate change or coastal development.

What we do know is that flamingos in large flocks in the wild are gregarious and fiercely loyal. They perform group mating dances. Parents dote on chicks, gathering them into crèches for protection while both males and females fly off to search for food. And when danger looms, thousands move as one – a ballet that may increase the odds of survival in a perilous world.
