Flamingos are flocking to a place inhospitable to humans to start their search for mates.

PEOPLE has an exclusive look at the "toxic" locale, which is highlighted in the new National Geographic show . The series, narrated by , gives viewers an up-close look at some of the world's most magnificent animal migrations and trips, including the mating journey of the lesser flamingo, a bird species native to sub-Saharan Africa.

In the exclusive clip, a flamboyance of the birds stop at Kenya's Lake Bogoria, a salt lake "so toxic it can burn human skin," Renner shares in his narration. Thankfully, the lake is ideal for thick-skinned lesser flamingos who visit the spot to put on weight before finding their mates.

The video focuses on a female flamingo who is making her first migration. During the three weeks she spends at Lake Bogoria, she eats 80 gallons of protein-rich spirulina "soup" from the lake's water daily.

The spirulina helps the bird gain weight quickly and transforms her feathers from a pale pink to the vibrant hue many associate with flamingos.

"To win the dating game, she's got to double her weight," Renner says over the clip.

The flamingo's search for dating success does not stop there. After putting on pounds and nourishing a bright pink color, the bird must fly from Lake Bogoria to the next stop on her journey.

"This lake might have food, but it is not the place to find a mate. To have any hope of finding love, she will have to follow the rest of the flock," Renner says over a shot of numerous flamingos taking off from the lake to continue the search for love.
