The **flamingo** (*Phoenicopterus*) is [known for its elegant posture](https://noticiasambientales.com/animales/censo-de-flamencos-hay-cerca-de-2500-en-esta-region-de-sudamerica/) in shallow waters, but what appears to be a tranquil filter-feeding image is actually a complex system of **active hunting**.
Researchers from the **University of California, Berkeley** have revealed that these birds use biomechanical techniques to catch their prey by generating **eddies with their legs and beaks**, concentrating small organisms such as **copepods and brine shrimp**.
According to the expert **Víctor Ortega Jiménez**, leader of the study, *”flamingos are strategic predators that design eddies to capture moving animals.”* This revelation changes the perception that they simply **passively filter water**.
## The beak tornado: a clever trap
The flamingo’s beak, with its **inverted L-shaped structure**, is specialized for **feeding upside down**.
– Through the **skimming technique**, the flamingo pushes its head forward while rapidly opening and closing its beak.
– This movement generates **vortex streets**, trapping its prey in small whirlpools.
*”They are not just filtering passive particles, they are actively hunting,”* emphasized Ortega Jiménez.
Furthermore, this mechanism could **inspire the development of technologies** such as **self-cleaning filters**, [systems for collecting **microplastics**](https://noticiasambientales.com/ciencia/microplasticos-en-tortugas-marinas-un-riesgo-invisible-para-la-biodiversidad/), and amphibious robots adapted to move in muddy terrains.
## The biomechanics of flamingos and their impact on science
Ortega Jiménez, in collaboration with universities in Georgia and the **Nashville Zoo**, conducted studies with:
– 3D models of **legs and beaks** to replicate the feeding process.
– **Laser filming** to analyze water flow around the flamingos.
– Computational simulations confirming the formation of vortices in the water.
They also discovered that the **beak chattering** multiplies the number of captured prey by **seven**.
## A future of nature-inspired innovation
The findings reveal that flamingos are **water architects**, creating moving structures to enhance their feeding.
Now, researchers plan to delve into the functioning of their **piston-like tongue** and the **serrated edges of their beak**, seeking new scientific applications.
*”Flamingos have evolved to efficiently capture tiny and agile organisms”*—concluded Ortega Jiménez.
