      <description><![CDATA[Photo credit Cvmontuy, CC BY-SA 3.0. Twice a year, on the spring and autumn equinoxes, something remarkable happens at Chichén Itzá. As the sun sets, shadows creep down the northern staircase of El Castillo pyramid, creating the illusion of a serpent descending from the temple to the stone serpent head at the base. But the acoustic engineering is equally remarkable: clap your hands at the base, and the pyramid returns a chirping echo that sounds like the quetzal, the sacred bird of Mesoamerica.
