Cave of Swallows, San Luis Potosi
The Cave of Swallows is a natural gulf located in the town of Aquismón belonging to the Mexican state of San Luis Potosi 21 ° 35'59? N 99 ° 05'56? O? /? 21.59972,-99.09889Coordenadas: 21 ° 35'59? N 99 ° 05'56? O? /? 21.59972, -99.09889. In particular, it is a karstic cave formed by water erosion in a waterproof failure of a plain stone calizaque has the characteristic of having a well outside opening narrower than the bottom, giving it a generally conical. The depth of the chasm is about 376 meters.The top opening is at ground level and has a diameter close to 60 meters, while the background has a maximum aperture of 300 meters by 60 at its narrowest. This site also has the distinction of being a natural refuge for birds, and that contrary to what its name implies, they are not swallows. This apparent contradiction is that the species can be found in the Cave of Swallows, swifts are in fact (though not common swifts, Apus apus, as these are birds of the Old World), often confused with the realswallows. The cave is also possible to find a species of parrots (Aratinga holochlora), locally called Parrots of cave.
