Frio Cave, like all bat emergence sites, offers extraordinary perspectives of circle-of-life drama when the hunters, the bats, become hunted by birds of prey and other predators.

As millions of bats emerge each night from Frio Cave to hunt for insects, birds of prey swoop and dive into the swirling moving mass of bats to latch onto their evening meal. Cave managers report seeing red-tailed hawks, zone-tailed hawks, and peregrine falcons circling the skies. On the ground, ring-tailed cats and skunks often wait at the cave’s entrance to snag their dinner.

Frio Cave is the seasonal migratory roost for ten million Mexican free-tailed bats (Tadarida brasiliensis), one of the largest colonies of migratory bats in the world, second only to Bracken Cave Preserve. Both caves are located in Texas Hill Country. Like Bracken Cave, female bats migrate from Central Mexico to Frio Cave during the spring to give birth and nurture their pups through the summer. Nightly, the bats fly from the cave for their daily nourishment, providing bat-viewing visitors with a remarkable experience.

To exprience the bat emergence at Frio Cave requires reservations and modest admission fees. Guides escort visitors to an easily accessed hilltop location for optimum and informed viewing.
