How do flamingos filter food from water?

Flamingos filter food from water using their specialised beaks and a technique called filter feeding. They sweep their heads upside down through shallow water, drawing water and mud into their beaks. Inside their beaks, comb-like structures called lamellae trap small organisms like algae, shrimp, and plankton. The flamingo then expels the water while retaining the food. This feeding method allows them to thrive in nutrient-rich wetlands, giving them their distinctive pink hue due to the carotenoids in their diet.
