The Mexican Cave of Swallows and why it got its name?
The Swallow Cave owes its name to the abundant colonies of birds that live on the inner slopes of the tunnel. Locals call this place “the basement of Swallows” but birds of this genus are practically absent in it. For the most part, the cave is occupied by swifts and parrots. Swallows probably lived here at the time when the cave was given this nickname.
