|18-SEP-1799||visited by Alexander von Humboldt.|
|1832||An anonymous Englishwoman publishes a book for children with some animal stories. Included is a chapter which describes the habits of the guácharo. It appears to be based on the work of Humboldt.|
|1836||The famous naturalist Alcide D'Orbigny published a book describing a fictitious character who travels the American continent. Written as a novel, it is based on the descriptions of many authors. In this context the description of the Cueva del Guácharo appears to be based entirely on the work of Humbold.|
|13-MAY-1842||The physiologist and German anatomist Dr Johannes Mueller (1801-1858) presents before the Academy of Sciences of Berlin a general note on the anatomy of the guácharo, using the publications of Alexander von Humboldt and Ferdinand L'Herminier.|
|1850||the German geologist Hermann Karsten (1817-1908) during a visit to the County of Cumaná, visits Cueva del Guácharo and studies the surrounding geology.|
|1859||The results of these studies are published and include an engraving of the mouth of the cave based on one of the paintings of Ferdínand Bellerman.|
|1860||The geologist George Parkes Wall (1832-1912) publishes an essay on the geology of Venezuela and Trinidad. During his time in the field, probably during 1858-1859, he visits the cave and carries out a geological reconnaissance of the Caripe area. He indicates that the thickness of the limestone is between 700 and 800 feet and he presents the first geological cross section of the Guácharo Hills.|
|1884||The prolific English writer William Henry Giles Kingston (1814-1880) publishes a novel on touring and risks in Venezuela. One on these is set in a cave and the account of Cueva del Guácharo, is very similar to the description given by Humboldt.|
Guácharo Cave houses one of the largest known colonies of the guácharos or Oil Birds or Diablotin (Steatornis caripensis). They are of a dark grey-blue colour, grow up to a size of 60cm and a wingspan of 110cm, and look like a bird of prey. Unique among birds is the ability to navigate using high-pitched squawks for echo-location like bats.
The nocturnal birds leave the cave every evening after dark to feed on fresh fruit. The fruit and seeds they bring back into the cave continuously, are the base of a whole ecosystem of plants and animals, living in the cave. Many seeds start to grow in the moist and fertile cave floor, but without sunlight their life is rather short. Among the animals feeding on the remains of the birds are wood-louses, crickets, millipedes, mice, fish, and crabs.
Alexander von Humboldt made the first scientific exploration of the cave. He observed the bats, the birds, and the other animals in the cave and described them in his book about this South America journey. He named the birds Fettschwälme, which is the base of the above names in other languages. As this book was sold many times all over Europe, a very early bestseller, the cave became rather famous. But because of its remote location, at this time like today, only a few people were able to visit the cave.
When Alexander von Humboldt visited the cave in 1799 the local monks described to him, how the local Indians hunted the birds for their fat deposits. At midsummer they entered the cave with long poles and destroyed most of the thousands of nests lining the high roof. The young birds were killed and stripped of the layer of fat between their thighs, which was melted in clay pots over fires and filtered to produce a pure, clear, odourless liquid. As superstitious dread prevented the Indians from entering very far into the cave, and then only on an annual basis, the colony managed to survive!
Alexander von Humboldt visited only the first 472m of the cave, as his native guides refused to proceed into the cave any further. But he saw the most interesting feature of the cave, the birds, and described this in his book. Because of his great influence a monument of Humboldt was erected opposite the cave, at a view which was painted by the travel companion of Humboldt.
After closing time your can camp near the entrance of the cave at a cost of $5 per tent. This is an ideal spot to watch the birds fly out at around 19:00 and return about 4:00.
