A Diversity of Birds

Macaws: Scarlet, Great Green, and More

Macaws, especially the Scarlet (Ara macao) and Great Green (Ara ambiguus), are iconic in Costa Rica. These brightly colored parrots are often seen in pairs, their loud calls echoing through the rainforest. Scarlet macaws frequent areas like Carara National Park, while Great Green macaws thrive in the northern lowlands near Sarapiquí. Their striking colors and social behavior make them a favorite among birdwatchers and photographers.

The Beautiful Quetzal

The Resplendent Quetzal (Pharomachrus mocinno), a symbol of beauty and freedom, can be spotted in the highland cloud forests of Monteverde and San Gerardo de Dota. Known for its iridescent green feathers and long tail, this bird is revered in Costa Rican culture.

Toucans

Toucans, such as the Keel-billed toucan (Ramphastos sulfuratus) and Chestnut-mandibled toucan (Ramphastos swainsonii), add a splash of color to the rainforest canopy. Their oversized, vibrant beaks are not just eye-catching but also help them reach fruit on distant branches.

Hummingbirds

In Costa Rica you will find over 50 species of hummingbirds, including the Violet-crowned woodnymph and Green hermit. These tiny birds, and two that are endemic: the coppery-headed emerald (Microchera cupreiceps) and the mangrove hummingbird (Amazilia boucardi). Often seen flitting among tropical flowers, play a crucial role as pollinators in the ecosystem.

Rainforest Reptiles and Amphibians

Red-Eyed Tree Frog

With its vibrant green body, red eyes, and orange feet, the Red-eyed tree frog (Agalychnis callidryas) is an emblem of Costa Rican wildlife. Found in lowland rainforests, these nocturnal amphibians are best spotted at night.

Poison Dart Frogs

Costa Rica is home to several poison dart frog species, such as the Strawberry poison dart frog (Oophaga pumilio). Despite their small size, their bright colors warn predators of their potent toxicity.

Crocodiles and Caimans

The American crocodile (Crocodylus acutus) thrives in brackish waters like those in the Tarcoles River, where boat tours offer close encounters. Smaller spectacled caimans (Caiman crocodilus) can be found in quieter freshwater habitats.

Green Iguana

Often seen basking in the sun, the Green iguana (Iguana iguana) is one of Costa Rica’s most recognizable reptiles. These herbivores play an essential role in seed dispersal within their habitats.

Mammals of Costa Rica

Monkeys: Howler, Spider, Capuchin, and Squirrel

Costa Rica’s forests resonate with the guttural calls of Howler monkeys (Alouatta palliata), especially at dawn. Spider monkeys (Ateles geoffroyi) are agile climbers, while White-faced capuchins (Cebus imitator) are known for their intelligence. Squirrel monkeys (Saimiri oerstedii), the smallest of the group, can be spotted on the Osa Peninsula.

Sloths

Both the two-toed sloth (Choloepus hoffmanni) and three-toed sloth (Bradypus variegatus) can be found lazing in trees throughout Costa Rica. These slow-moving mammals are surprisingly adept swimmers and a delight to observe.

Anteaters

The Northern tamandua (Tamandua mexicana) and Giant anteater (Myrmecophaga tridactyla) feed primarily on ants and termites. Their specialized tongues and claws make them fascinating creatures to spot in the wild.

Tapirs

The Baird’s tapir (Tapirus bairdii), Costa Rica’s largest land mammal, roams the dense rainforests of Corcovado National Park. With its prehensile snout, it plays a vital role in seed dispersal.

Felines: Jaguar, Ocelot, and More

The jaguar (Panthera onca), a symbol of strength and mystery, prowls the protected areas of Corcovado. Smaller felines like the ocelot (Leopardus pardalis) and margay (Leopardus wiedii) are equally elusive, making night tours your best bet for sightings.

Bats

Costa Rica’s 113 bat species account for nearly half of the country’s mammal diversity. From insect-eating bats to nectar-feeding ones like the long-tongued bat, they are vital to the ecosystem as pollinators and pest controllers.

Sea Turtles

Costa Rica’s beaches host nesting grounds for sea turtles, including Leatherback, Green, and Olive Ridley turtles. Tortuguero National Park and Ostional Wildlife Refuge are prime spots to witness nesting or hatchlings making their way to the ocean.
