Get to Know the Fauna of Corcovado National Park (Costa Rica)
We invite you to explore Corcovado National Park, one of the most biologically diverse parks in Costa Rica. In this wonderful environment of virgin rainforest live a great variety of animals, some in danger of extinction, including birds, mammals, insects, amphibians, and reptiles. It also stands out for its marine fauna.
Some facts about this natural reserve
Created in 1975, the park is located in the Osa Peninsula, in the southwest of this Central American country. It’s about 350 km (220 mi) from San José, the Costa Rican capital. It’s considered a natural laboratory, ideal for studying tropical ecosystems and their relationships.
According to National Geographic, this is the most biologically intense place on the planet. Its 42,560 ha (164 sq mi) of land and 3,354 ha (13 sq mi) of marine areas are home to 2.5% of the planet’s biodiversity.
A landscape of forests, large stretches of uninhabited beaches and thundering waterfalls make Corcovado a natural reserve of undeniable beauty. Regarding its fauna, we can point out that it has about:
- 140 species of mammals
- 400 species of birds, 20 of which are endemic
- 40 species of freshwater fish
- 117 species of amphibians
- 10, 000 types of insects
- 28 species of lizards

Other mammals in the reserve
This reserve is home to almost all of the few Baird’s tapirs —also known as the Central American tapir (photo below)— remaining in Costa Rica. There are also specimens of peccaries or skunk pigs, which are in danger of extinction due to habitat degradation and poaching.
The reserve is also home to three-toed sloths and coatis, which are among the most numerous mammals in the country. The latter resemble raccoons and have a thin, ringed tail and an elongated nose.
The reserve is also home to:
- Agoutis, a genus of rodents
- River otters

The harpy eagle, which was thought to be extinct in the area, and the king vulture, a species of American vulture, can also be seen. And let’s not forget the 16 species of hummingbirds.

Among the snakes, we can find the boa constrictor, the fer-de-lance, and the Southern American bushmaster —also called Atlantic bushmaster. Speaking of iguanas, we can see the black spiny-tailed iguana (photo above), which looks like a small dinosaur with the ability to glide through water.
There’s also an abundance of spiders with their webs of various shapes. Also, out of the great variety of insects that the park houses, we can highlight:
