Llanos Savannas

About the Area

This ecoregion is the best example of tropical savannas in South America with high floristic and habitat diversity.
Being one of the world's largest wetland complexes, the region has its share of streams, rivers, marshes, and more - and with them many species not typically found in savanna ecosystems, such as the Orinoco crocodile (Crocodylus intermedius).

Local Species
Found here is the White-bellied spider monkey (Ateles belzebuth), Tamandua (Tamandua tetradactyla), Black-bellied tree duck (Dendrocygna autumnalis), White-faced tree duck (Dendrocygna viduata), Roseate spoonbill (Ajaia ajaja).

Other species include the endemic Orinoco piculet (Picumnus pumilus), and the Capybaras (Hydrochaeris hydrochaeris) - the world's largest rodents that feast on grasses and other plants to keep their 50 kg bodies well-fueled!

In addition, parts of these savannas support breeding populations of the Giant anaconda (Eunectes murinus).

Grazing, burning, draining, conversion to agriculture, and over hunting are all threats to the biodiversity found in this ecoregion. Dickcissel sparrows (Spiza americana) - birds from the Great Plains, winter here and are endangered by pesticides.
