Riddle us this: Which animal is pink, curved beaked and a master of the physics required to create water tornadoes? If you guessed flamingos, you're right. New research out this month in the journal Proceedings of the National Academy of Sciences shows that across a range of harsh environments, flamingos have become masters — of physics, fluid dynamics and so much more — all in pursuit of their filter-fed prey. Short Wave host Regina G. Barber sits down with biomechanics researcher Victor Ortega Jiménez to hear all of the incredibly involved lengths these birds go through to get their prey.

What unique feeding behaviors do flamingos exhibit?
Because one of the mandibles keeps stationary and the other is moving. So that asymmetry is causing this directional flow. And that's something that flamingos do in comparison with other filter feeders like whales.
Yeah. So flamingos are different filter feeders than whales. They're doing a lot more. Got that. OK. What other behaviors did they study? The second behavior that they looked at was the fact that flamingos stick their head like straight in and out of the water. It's like dipping. And because of the shape of the beak, this also creates vortexes.
To study this part of eating, they trained these Chilean flamingos at the Nashville Zoo to feed in this aquarium tank. And they recorded these little water tornadoes like with each dip of their beak. And this helped the food drift up into their beaks. That sounds delicious. OK, so flamingos. Quick summary. It's the chattering of the beaks in combination with the shape of the beak.
Yeah, like it's all of those things working together to like co-create these vortexes. What about the foot stomping? Yeah, so like Victor and his team studied that as well. They created this like mechanical flamingo foot that was like flat when you stepped into the water.
We know that flamingos, when they are stomping, the foot to the sediments is opening.
And then when it came up, it kind of retracted like an umbrella.
And then when it's getting up, it's collapsing. What they are doing is producing a vortex.
And that's how flamingo feet actually work in the wild. And in the lab, they saw that, yes, this motion also created vortexes. They could stomp for food? Yep.
Well, they are stomping frequently or marching like a dancing.
