Caribbean flamingos are typically social birds, living in flocks of up to tens of thousands. Within this group, they will feed together, breed together, and fly together. Having very distinctive eating habits, they use their feet to stir up mud and plunge their bill upside down underwater. This pumping action allows them to pick up a variety of small animals and algae. The flamingo’s upper and lower jaw, which is ridged, acts as a filter, straining out water and mud at the sides of the bill. This entire process is know as filter feeding.
The bright color of a flamingo is caused by the presence of carotenoid pigments found in the algae and crustaceans that make up their diet
