Why do I say the flamingos eat backwards? Because in fact, the beak structure of the Flamingos is completely different from most other birds, and also humans. Their upper beak is very flexible, can move up and down, but the lower beak is held in place.
Therefore, the way the Flamingos eat is: Submerged head submerged in water, head turned upwards (like hook); The legs can clear the mud to flip small animals and larvae. When they opened the upper beak, they pulled their tongue inward to allow water to overflow. Then close the beak and push the water through your nose with your tongue. The flamingo nose has a special structure (like a honeycomb) that filters out food.
