Other animals

The Magdalena River and its valley crosses a wide variety of ecosystems, like páramo in its headwaters, dry forest in the upper part of its valley, rainforest in its middle course, and swamps and wetlands in its lower course. The spectacled caiman, green iguana and brown pelican are abundant in these ecosystems but other animal species like the West Indian manatee, Magdalena tinamou, Todd's parakeet, American crocodile, Colombian slider, Magdalena River turtle, Dahl's toad-headed turtle and red-footed tortoise are in danger of extinction.

In addition, there is a possible risk posed by invasive hippopotamus. Originally imported by Pablo Escobar, these hippopotami became feral following his demise, and have since expanded beyond their original home on Hacienda Napoles into nearby regions of the Magdalena River.
