The Cano Negro Refuge provides vital habitat to many species of wildlife.  There are three species of monkeys, including spider, howler and capuchins.  Big cat species include ocelots, jaguars, and pumas, though none of which are often seen.  In addition, there are sloths, anteaters, tayras, deer, and pacas.  The refuge is well-known for its reptiles which include caimans, emerald basilisks, iguanas, and various snake species. 

This area is also an important layover for migratory birds.  Some of the most prominent species include roseate spoonbills, green-backed herons, anhingas, white ibis, northern jacanas, blue-winged teals, jabirus, wood storks, ospreys, snail-kites, and many other species.

More about the Cano Negro Refuge

There is a high density of wildlife in Cano Negro Wildlife Refuge as much of the surrounding area is farmland. In essence, this creates a metaphoric island of rainforest and wildlife allowing for a centralized location to see a variety of creatures. Riverboat tours are the best way to spot wildlife as the guides can point out species that are sometimes not visible to an untrained eye.

Cano Negro is an excellent location for freshwater sport fishing.  Species that inhabit the waters include giant tarpon, which can grow to over 150 pounds, snook, guapote, and gar.  When the tarpon are going after a meal near the surface, it can seem like a mini explosion in the water!  Gars are nearly always present, coming to the surface to slurp air.
