Nature: The Bat Man of Mexico

Premieres Wednesday, June 30 at 8 p.m. on PBS (check local listings), and the PBS Video app

Since ecologist Rodrigo Medellin first kept bats in his bathroom as a child, he has dedicated his life to saving them. Now Mexico’s most famous export, tequila, is at stake. Medellin’s beloved lesser long-nosed bat is crucial to the liquor – it pollinates the plants the drink is made from. To save these bats from extinction, Medellin must track the bats’ epic migration across Mexico, braving hurricanes, snakes and seas of cockroaches. Sprinkling harmless UV dust on bats and following their glowing guano across the desert, Medellin devises innovative methods to conserve Mexico’s bat population. Narrated by David Attenborough.

Buzzworthy Moments:

  • More than three million bats live in the caves of Calakmul. To avoid being eaten, they form a living tornado when they fly. In this whirling mass, it’s almost impossible for their predators to choose a target.
  • To track the migration patterns and distances of the lesser long-nosed bats, Medellin coats the bats he catches in harmless UV dust, which they lick off and digest. The glowing dust passes through their system, and by tracking the glowing bat droppings, he can prove how far they’ve flown. This is a method used when tracker technology is unavailable.
  • Medellin sets up remote cameras in a bat “nursery.” Bats synchronize their births so that a colony’s newborns all arrive over the course of 2-3 weeks. The camera catches a mother giving birth – the first time this behavior has been filmed.

Noteworthy Facts:

  • There are more than 1,200 species of bats in the world.
  • Bats are the main pollinators of agave plants. Tequila is obtained through the distillation of juices from agaves. More than a quarter billion liters of tequila were exported from Mexico in 2020.
  • For centuries, bats were hated in Mexico because of their association with evil. People would hunt them down and kill them, burning them in their caves. In the early nineties, their populations crashed, with the lesser long-nosed bats facing extinction.
