Flamingos display active hunting behavior by using fluid dynamics to draw out and trap quick-moving invertebrates for feeding.
When feeding, flamingos lift their flat upper forebeak to create suction, forming a vortex to draw food particles and prey from the muddy sediment.
Flamingos open and close their mandibles rapidly in a behavior called chattering, creating a flow that draws particles and swimmers towards their beak at about seven centimeters a second.
Flamingos utilize Von Karman vortices to create a recirculation zone near the tip of their beak, where brine shrimp eggs get caught and delivered to their mouth, showcasing their sophisticated hunting techniques.
