Geography and Hydrology:
The wetlands of Caño Negro are primarily formed by the Frio River and its tributaries. The region experiences a tropical climate, characterized by distinct wet and dry seasons.
During the rainy season, the water levels rise, flooding the plains and creating an intricate system of waterways. This flooding is essential for maintaining the health of the wetlands and supporting the diverse array of life that depends on it.
Caño Negro is celebrated for its exceptional biodiversity, which includes a wide variety of flora and fauna. The wetlands provide a habitat for numerous bird species, amphibians, reptiles, mammals, and fish.
The area is especially renowned as a birdwatcher’s paradise, with over 350 species of birds recorded. Notable bird species include herons, egrets, ibises, anhingas, and the rare and endangered Jabiru stork.
The refuge is also home to various mammals, such as howler monkeys, white-faced capuchin monkeys, jaguars, ocelots, and river otters.
