La Sima de las Cotorras (Sinkhole of Parrots)

Thousands of green parakeets inhabit the trees at the bottom of this massive plateau, giving rise to its namesake—Sinkhole of Parrots. Each morning between 5:30 and 6 a.m., as well as each evening from 4 until 5 p.m., these colorful birds dart through the sky as they depart for and return from the outside world. Travelers can bear witness to this spectacle, which is unlike any other, and which hits its peak between March and October. Sinkhole of Parrots attracts more than 80 other species of birds, including honeycreepers, thrushes and woodpeckers, making it a destination for avian aficionados. 
In addition to an am impressive array of birds, travelers will find close to 50 ancient rock paintings nearly 70 meters below ground level. Visitors can climb down rocky cliffs to check out these images left by unknown artists between 5,000 and 10,000 years ago.
