Cincinnati Zoo on Instagram: "This male greater flamingo demonstrating the usefulness of their curved bill while eating! Flamingos filter feed by sucking water & mud in at the front of the bill & then pumping it out again at the sides. Plates called lamellae act as tiny filters, trapping shrimp & small water creatures for the flamingo to eat. Make memories all year long! Zoo memberships are on sale now. @frischsbigboy #flamingo #birds #animals #zoo #zookeeper #cincinnatizoo"
