Bat VolcanoFebruary 08, 2020
For as the eyes of bats are to the blaze of day, so is the reason in our soul to the things which are by nature most evident of all.

The eruption of a volcano full of bats
Starting at about an hour before dusk every day of the year, seven species of bats exit the cave to forage for insects in the night sky. The exact number of bats is unknown but estimates place the colony’s size at between two to five million bats.
When the bats first start to fly out, it’s just a trickle of bats here and there. It’s hard to imagine the spectacle that is going to form before your eyes over the next hour or so. You can see why locals call the cave “El Volcan de Los Murcielagos” or Bat Volcano.
