Flamingos conjure ‘water tornadoes’ to trap their prey

Flamingos are known for their vibrant pink feathers and graceful appearance, but a recent study has revealed the fascinating feeding behavior of these elegant birds. Contrary to their calm demeanor, flamingos are skilled predators that use a unique technique to capture their prey.

The study, published in the journal Proceedings of the National Academy of Sciences (PNAS), sheds light on how flamingos create swirling water tornadoes to efficiently hunt for their food. Researchers from the University of California, Berkeley, Georgia Tech, Kennesaw State University, and the Nashville Zoo observed Chilean flamingos in captivity to understand their feeding habits.

Flamingos use a combination of their feet, heads, and beaks to create these water tornadoes, which help them concentrate their prey, such as brine shrimp, before consuming them. The birds’ specialized anatomy, including webbed feet and L-shaped bills, allows them to effectively trap and filter small aquatic organisms.

According to Victor Ortega Jiménez, a biologist and co-author of the study, flamingos are highly adapted for filter feeding. Their unique feeding strategy involves churning up sediment with their feet, creating mini water tornadoes to draw prey closer, and using their beaks to filter out food particles.

The researchers also found that the shape of flamingo beaks plays a crucial role in their feeding behavior. The flattened, angled front end of their beaks allows them to skim the water’s surface and create sheet-like vortices that trap prey. This specialized technique enables flamingos to capture agile animals like brine shrimp and copepods.

The study’s findings have implications beyond the animal kingdom, as the fluid principles observed in flamingos could inspire new engineering applications. By understanding how flamingos concentrate and capture food particles, engineers may develop more efficient systems for filtering water or cleaning up pollutants like microplastics.

Overall, the study provides valuable insights into the remarkable feeding behavior of flamingos and highlights the potential for biomimicry in engineering applications. By studying the natural world, researchers can uncover innovative solutions to complex challenges, inspired by the incredible adaptations of animals like the pink flamingo.
