Rodrigo Medellin loves bats. The Mexican conservationist has been obsessed with the often maligned creatures for over six decades. As a child, he kept blood in ice cube trays in his parents' freezer, to feed to his pet vampire bats. He went on to create Mexico City’s first ever bat festival, and to work with governments, universities, NGOs and researchers all over the world. To many, Rodrigo IS the "bat man."

Like many Mexicans, he is also fiercely proud of the country’s native spirits: tequila and mezcal. The agave spirits are hugely important for Mexico’s economy, especially in the states of Jalisco and Oaxaca. Exports of the drinks are worth billions. Tequila and mezcal have become increasingly popular in recent decades, with sales boosted by big budget celebrity-owned brands designed to appeal to the US consumer. From Kendall Jenner to George Clooney, US celebrities have been riding high on the mass market appeal of the liquor.

But the boom in these industries has had unintended consequences for Rodrigo's beloved bats. Often the agave the spirits are made from is harvested early, before the slow-growing plant can flower. This means bats cannot feed from the nectar, and critically, they can’t do their job as pollinators. This contributes to agave monocultures which are susceptible to disease and blight.

Rodrigo explains how he wanted to change the way the industry works, creating a “bat-friendly” certification for tequila and mezcal producers who leave 5% of the agave untouched, to bloom. But why have so few brands been certified, why is the programme controversial for some producers, and why are bats a tricky sell as far as conservation for many people and communities? Sarah Treanor spends time with Rodrigo in Mexico City and Oaxaca to find out.
