This is Berthnor.

In Marcikita Argentina, one of South America's biggest salty wetlands, a biologist spends her days studying shorebirds.

My name is Marcela Castellino and I always get interested in the birds.

Marcela works as a conservation specialist for Manumet's flyway steam, visiting wetlands, salda goons and salt flats.

She surveys shorebirds to track their population and strengthen their conservation.

Since she was a child, she's been keen on learning more about a species that she and her sister Marina often saw in Marcikita,

a species that she describes as superheroes.

This is Wilson's falaro.

You can cross a lot of obstacles and these incredible distances and have these physiological changes that are impressive.

They're impressive and can traverse past distances and obstacles she's saying here.

They fly in synchronized movements almost like a dance Marcela is saying.

After summers have ended in North America, they come back to Marcikita to continue these dance.

They feed, they swim in circles, swirling the water and stirring up things to end it.

Marcela and her team are working to conserve the bird and their electric, elliptical, and circular dance.

This show is part of a series on Manumet's shorebird conservation research and it's also available in Spanish.
