To the left of the rock you can climb Ceru Grandi, though you'll need to scramble on all fours near the top. The top of the middle terrace has a few caves which were once mined for phosphate. 8 Boca Cocolishi has many fossil shells on the top of its terrace. This bay is famous for its flat bench rising above the surfline. The bench consists of calcareous algae and worm shells which cover the limestone and make it resistant to the wave action.
Erosion is actually less at such a protected spot.
The bench creates a quiet pool partly surrounded by sand which is about three feet deep and calm, no matter how turbulent the waves. The bird species found here include the yellow-winged parakeet, the yellow warbler, ground dove, common bananaquits, tropical mockingbirds and many more. Other parakeets may be present, but they have a tough time surviving the droughts on Bonaire, which occur every five or six years. Besides facing starvation and drought the birds have to feed in the village fruit gardens, where the parakeets are often caught and caged for show. 10 Boca Bartol is another prime birdwatching spot.
