Colombia is a megadiverse country

A country is recognized as a megadiverse if it meets two criteria: it must have at least 5,000 endemic plant species and include marine ecosystems within its borders. A species is considered endemic when found only in a specific, limited geographic area.

Colombia was one of the first countries recognized as a megadiverse by primatologist Russell Alan Mittermeier, the concept’s founder.

Colombia is considered the country with the highest biodiversity per square kilometer. According to the 2023 report from the Biodiversity Information System (SIB), Colombia ranks as the fourth most biodiverse country globally, with around 10% of the world’s species. It boasts the greatest diversity of bird species (over 20% of all known species), as well as orchids and butterflies.

This exceptional biodiversity stems from its various ecosystems, ranging from snow-capped mountains and tropical jungles to deserts. Factors such as climate conditions, temperature, humidity, and sunlight also contribute to this richness.

In October 2024, the city of Cali (Valle del Cauca department) hosted COP 16, the global biodiversity summit.

Exploring Colombia’s national parks in every natural region is the top way to uncover its astonishing fauna and flora.

Wildlife Across Colombia’s Regions

There is a variety of animals to see in each region.

Pacific Coast

The Pacific coast is a true biodiversity haven, with long beaches bordered by dense tropical rainforest, threaded with rivers and mangroves. The Serranía del Baudó is the only highland, and islands like Isla Gorgona offer exceptional flora and fauna.

This region is very rainy, even in the “dry” season, so your explorations often depend on the weather.

The Pacific coast will thrill bird watchers (around 800 bird species), herpetologists (frogs, including several venomous species and turtles), and whale enthusiasts (humpback whales and whale sharks).

Some animals are easy to spot here:

  • Humpback whale.
  • Several species of sea turtles.
  • Numerous hummingbirds (Mitchell’s Hummingbird – Calliphlox mitchellii).
  • The Green Basilisk (Basiliscus plumifrons), known for its ability to run on water.

Others are more elusive:

  • The Harpy eagle (Harpia harpyja), the largest and most powerful raptor of the rainforest.
  • The Baudó Oropendola (Psarocolius cassini), endemic to the Sierra region.

Among the more common endemic species, you’ll find:

  • The Golden Poison Frog or Colombian Kokoï (Phyllobates terribilis).
  • The Blue Anole (Anolis gorgonae), a stunning blue lizard native to Isla Gorgona.

Caribbean coast

The Colombian Caribbean coast (Eastern and Western sides) boasts a wide variety of ecosystems: dry tropical forests (Tayrona Park), humid forests (Trigana), coral islands (Rosario Archipelago), desert (La Guajira), mangroves (Isla Tintipán, Rincon del Mar, La Boquilla), and mountains (Sierra Nevada de Santa Marta). This rich natural diversity supports a wide range of wildlife and plant species.

The climate is generally warm year-round, with a rainy season (April to October) that can make trekking difficult or even impossible, especially in September and October in La Guajira. It’s a popular tourist region, so try to avoid peak season if you can.

Among the Colombian wildlife you can easily spot are:

  • Howler monkeys.
  • Numerous birds (cormorants, falcons, kingfishers) in the mangroves and marshes of Ciénaga Grande and around Mompox.
  • Toucans (in the Sierra Nevada and Rincón del Mar).
  • Sea turtles (along the western coast).
  • Many species of fish.

More elusive Colombian animals include:

  • Sloths.
  • The Cotton-top tamarin, endemic to the region.
  • The Golden Metaltail, a rare, endemic hummingbird found in La Macuira Park in La Guajira.

Los Llanos

With vast floodplains and several natural reserves, Los Llanos is, in my opinion, the perfect region for wildlife watching in Colombia.

The best time for a safari is during the dry season (December to March) as animals gather around the few remaining water sources in the savanna. It’s very hot here, so early morning or late afternoon is ideal for spotting animals as they gather at watering holes to drink. Many are also nocturnal.

Among the Colombian animals you’ll have no trouble spotting are:

  • Capybaras.
  • Caimans.
  • Deers.
  • Numerous birds, including several migratory species (around the Alta Gracia lagoon).
  • Various monkeys (howler, spider, woolly, and titi monkey).

You’ll need a bit more luck to spot:

  • Giant anteaters.
  • Otters.
  • Anacondas.

It’s even harder to catch a glimpse of jaguars.

Andean region

The Colombian Andes region offers breathtaking landscapes: páramos (a unique ecosystem), canyons (Chicamocha), deserts (Tatacoa), lakes (Laguna de Tota), rainforests, and cloud forests. Numerous national parks feature trails for exploring the region’s rich flora and fauna.

With a wide range of climates and significant temperature changes, it’s worth planning carefully if you’re heading out for an adventure. Avoid the rainy seasons (April-May, September-October) if you plan to explore the páramos.

Some of the Colombian wildlife you can easily spot in the Andes region includes:

  • The Andean cock-of-the-rock.
  • The Crested oropendola.
  • The Andean motmot.
  • Many other bird species, such as tanagers, hummingbirds, and warblers.

Other species are more challenging to find:

  • The Andean condor – endemic to the Andes mountains.
  • The Spectacled bear, also endemic.
  • The Stubel’s hummingbird, critically endangered.

Plant lovers will also be captivated by endemic species like the frailejón and the majestic wax palms of the Cocora Valley and Toche (near Salento).

The Amazon

A lush jungle crisscrossed by the vast Amazon River, expansive plains, and unique rock formations make the Amazon a paradise for nature lovers.

If you’re planning an adventure in this region, prepare for a hot, humid climate, plenty of mosquitoes—especially in the rainy season—and often basic accommodations.

Life in the Amazon follows the rhythm of the river. I recommend visiting during the low-water season (August to October) to increase your chances of seeing wildlife.

Some Colombian animals are fairly easy to spot in the Amazon:

  • Numerous insect species: tarantulas and other spiders like the banana spider, grasshoppers, and giant stick insects.
  • Several species of tiny frogs.
  • Toucans.
  • Macaws.
  • Endemic monkeys like the Saimiri, Tamarin, and Churuco.
  • Pink river dolphins, endemic to the Amazon River.
  • Fish like the famous piranha and the pirarucu, the largest freshwater fish and endemic to the Amazon.
  • The hoatzin (Opisthocomus hoazin), a fascinating bird.
  • Caimans.

Some animals are harder to encounter:

  • Two-toed sloth.
  • Anaconda.
  • Harpy eagle.
  • The elusive jaguar.

If you’re a plant lover, you’ll be thrilled by iconic species like the majestic Ceiba tree and the giant water lily, both of which are easy to admire in the Amazon.

Around 2,020 bird species inhabit Colombia’s jungles, mountains, and plains, representing over 20% of the world’s bird species. This makes it the richest country in terms of bird species globally and an ideal destination for birdwatching.

Colombia is home to 85 endemic species and 100 threatened species. Additionally, it’s a critical stop on the American continent for migratory species traveling from north to south.

Among the most iconic species, the Andean condor stands out. With dozens of species, hummingbirds are also highly represented in Colombia, with some endemics like the Black-backed Thornbill, Buffy Helmetcrest, and Blue-bearded Helmetcrest, all of which are threatened or endangered.

Other well-known or emblematic species include:

  • The Motmot or Barranquero.
  • The Harpy eagle.
  • The Quetzal – 13 endemic species.
  • The Cacique or Oropendola (also called Mochilero).
  • Toucans – several species.
  • The Andean cock-of-the-rock.
  • Tanagers (small songbirds) – Colombia hosts several species, such as the Black-and-gold Tanager and Gold-ringed Tanager, both endemic and vulnerable.

Mammals of Colombia

With 450 recorded species, mammals are well represented among the animals of Colombia, placing the country in the top quarter globally for the number of terrestrial mammal species. The diversity of often hard-to-reach ecosystems suggests that this number may grow as exploration and discovery continue.

Some of the most well-known or iconic mammals include:

  • Monkeys – Colombia is home to several monkey species, such as the Cotton-top tamarin, the Black-headed spider monkey (a threatened species), the Red howler monkey, the Woolly monkey or Churuco, the Titi monkey, and the Pygmy marmoset (the smallest primate in the world).
  • The giant anteater.
  • The giant otter – a threatened species.
  • The capybara.
  • The spectacled bear.
  • The jaguar.

Among marine mammals are the humpback whale and the pink river dolphin (the boto).

Other mammals, though less known, are also present:

  • The white-tailed deer.
  • The mountain tapir – a threatened species.
  • The tamandua, a relative of the anteater family.

Reptiles of Colombia

With over 580 identified species, Colombia ranks as the sixth most reptile-rich country in the world.

The most represented groups include:

  • Caimans, such as the Black caiman, Cuvier’s dwarf caiman, and the Spectacled caiman.
  • Turtles (33 species), with 15 endangered species and 3 endemic ones. The most well-known include the green sea turtle, the hawksbill turtle, and the impressive leatherback turtle.
  • Over 230 lizard species, including iguanas, various anole species such as the blue anole, and several basilisk species, including the green basilisk.
  • Around 300 snake species, including the famous green anaconda, as well as the Boa imperator and Boa constrictor.

Amphibians of Colombia

Among Colombia’s most prominent animal groups are amphibians, with over 750 recorded species.

There are two very interesting groups:

Glass frogs (or Fleischmann’s glass frogs), typically no larger than 25 mm, are usually a lemon-green color. They’re named for their translucent abdominal skin, which reveals their bones, intestines, and heart. This transparency, which changes with their surroundings, makes them nearly invisible—a valuable survival camouflage compared to “opaque” frogs. Among the glass frogs in Colombia are Burrowes’ Giant Glass Frog, a threatened species, and the Spiny Cochran Frog.

The other well-represented amphibian group in Colombia is poison frogs, which store venom in skin glands. The most famous is the Golden Poison Frog or Kokoï of Colombia, endemic to Colombia’s Pacific coast and known as the world’s most toxic frog. Indigenous tribes would coat their blowgun darts with its secretions.

Butterflies of Colombia

With nearly 3,700 identified species, Colombia hosts the largest butterfly species in the world. It’s estimated that 20% of the planet’s butterflies are found here, with over 200 species being endemic.

Some of the most remarkable species include:

  • The Blue Morpho, a huge butterfly (with a wingspan of around 120 mm) whose wing tops are a brilliant metallic blue. Highly prized by collectors in the 20th century.
  • The Monarch, another large butterfly, recognizable by its orange wings veined with black patterns. This migratory species forms impressive gatherings during migration.
  • The Caligo, also known as the “owl butterfly” due to the large, round eye-like spots on the underside of its wings, which resemble an owl’s eyes.
