Costa Rica Birds: A Complete Guide to 900+ Species and Where to Find Them

Costa Rica's national bird is the clay-colored thrush, known locally as the yiguirro. While unremarkable in appearance — it resembles a plain brown robin — the yiguirro is celebrated for its rich, melodious song and was designated the national bird because its calls are said to call forth the rains at the start of the wet season each May. It is found in every corner of the country, from urban gardens to forest edges, and is often the first bird that new visitors identify during a trip.

The resplendent quetzal is the most sought-after species for visiting birders. A member of the trogon family, the male quetzal has iridescent emerald-green body plumage, a crimson belly, and extraordinary tail feathers that can extend up to one meter in length. Once sacred to both the Maya and the Aztec civilizations, the quetzal remains a symbol of beauty and freedom throughout Mesoamerica. In Costa Rica, quetzals are found in highland cloud forests, particularly around Monteverde, Cerro de la Muerte, and the San Gerardo de Dota valley.

Scarlet macaws are among the most visually dramatic birds in the country. These large parrots, with vivid red, yellow, and blue plumage, are found along both coasts and are particularly abundant in the central Pacific region near Carara National Park and on the Osa Peninsula. Their raucous calls and habit of flying in pairs or flocks at sunrise and sunset make them one of the most memorable wildlife encounters in Costa Rica, even for non-birders.

Costa Rica's cloud forests — found between approximately 1,500 and 3,000 meters elevation — support some of the most specialized bird communities in the country. These forests, perpetually cloaked in mist and draped with mosses, epiphytes, and bromeliads, provide food and shelter for species found nowhere else in the world. The cool, humid conditions favor frugivorous birds that feed on the abundant small fruits produced by cloud forest trees, particularly laurels of the genus Ocotea, which are the primary food source of the resplendent quetzal.

In addition to quetzals, Monteverde and similar cloud forests harbor three-wattled bellbirds — large, white-and-chestnut colored birds whose males produce one of the loudest calls in the avian world, a resonant metallic clang audible from more than a kilometer away. The bare-necked umbrellabird, with its remarkable crest and wattle, is another cloud forest specialty. Prong-billed barbets, golden-browed chlorophonias, and a remarkable diversity of flycatchers, warblers, and tanagers round out the cloud forest community.

The San Gerardo de Dota valley in the Talamanca Mountains is widely considered the most reliable quetzal-watching site in Costa Rica. The valley sits at approximately 2,100 to 2,600 meters elevation in the Chirripó National Park buffer zone and contains extensive primary cloud forest where quetzals feed on wild avocados. Several small lodges in the valley offer guided quetzal walks, and sightings of multiple males with full tail plumes are common between January and May, the nesting season.

The Caribbean lowlands of Costa Rica support a distinct bird community influenced by the proximity of South American species that entered Central America after the formation of the Isthmus of Panama approximately 3 million years ago. The forests around La Selva Biological Station in the Sarapiquí region, Tortuguero National Park, and the Braulio Carrillo National Park buffer zone are among the most productive birdwatching areas for lowland forest species in all of Central America.

La Selva Biological Station, operated by the Organization for Tropical Studies, has recorded over 460 bird species on its 1,600-hectare property — one of the highest densities of bird diversity ever recorded for a single site. Key species include the snowy cotinga, great green macaw (critically endangered), sunbittern, white-whiskered puffbird, and numerous antbird species that follow army ant swarms to feed on the insects and lizards flushed by the ants. Visiting La Selva with an experienced guide dramatically increases the number of species identified.

Great green macaws, closely related to military macaws but larger and more endangered, are found primarily in the Caribbean lowlands where they depend on mountain almond trees for nesting and feeding. The Sarapiquí region and the forests around Tortuguero are among the best places to see this endangered species in Costa Rica. Conservation organizations have worked intensively to protect mountain almond forest corridors specifically to support the great green macaw's remaining population, which numbers only in the hundreds in Costa Rica.

The Pacific coast of Costa Rica, from the dry forests of Guanacaste in the north to the humid Osa Peninsula in the south, supports a remarkably different bird community from the Caribbean side. The dry season concentration of water in seasonal wetlands creates extraordinary spectacles of waterbird aggregations during January through April, when thousands of wood storks, ibis, herons, and egrets crowd drying pools and rivers in the Tempisque basin of Guanacaste.

Palo Verde National Park in Guanacaste protects the most important freshwater wetlands in the Pacific region. From December through March, the park's lakes and marshes attract over 50,000 waterbirds, including black-bellied whistling ducks, roseate spoonbills, jabiru storks, and enormous flocks of various heron species. The jabiru, the largest flying bird in the Americas with a wingspan exceeding 2.5 meters, has one of its last remaining Central American breeding populations in the Palo Verde area.

Carara National Park, at the boundary between the dry and humid Pacific zones, is particularly celebrated for its accessibility from San José and its remarkable bird diversity. The primary forest along the Tárcoles River trail shelters scarlet macaws, trogons, motmots, and numerous raptor species. The riverbank below the highway bridge over the Tárcoles River is famous for American crocodiles and is also an excellent area for observing wading birds and shorebirds along the Pacific estuary. A short stretch of about 2 kilometers between this bridge and the park entrance is one of the most productive birdwatching walks in the country.

The Monteverde Cloud Forest Reserve and its surroundings on the continental divide above the Nicoya Peninsula are considered among the finest birdwatching destinations in the Americas. The reserve and the adjacent Santa Elena reserve together protect over 10,500 hectares of primary and secondary cloud forest. Over 400 bird species have been recorded in the Monteverde zone, including 30 species of hummingbirds. The quetzal, three-wattled bellbird, and bare-necked umbrellabird are the three flagship species that draw birding tour groups to the area year after year.

The Osa Peninsula in the far south of Costa Rica contains some of the most intact lowland tropical forest remaining in Central America, protected within Corcovado National Park. The park's 13 ecosystems and 400-plus bird species include virtually all of the country's most sought-after Pacific lowland species: scarlet macaws in large flocks, harpy eagles (extremely rare), crested caracaras, and the endemic black-cheeked ant-tanager, found only in the Osa Peninsula. Access requires either a flight to Drake Bay or Puerto Jiménez followed by a park entry via authorized guide.

The Sarapiquí region of the northern Caribbean lowlands, centered on the town of La Virgen and the Sarapiquí River, combines easy accessibility from San José with excellent lowland birding. La Selva Biological Station, the Tirimbina Biological Reserve, and the Rara Avis reserve offer guided birding walks at well-maintained research stations with experienced guides and birding infrastructure including spotting scopes and reference libraries. This region is accessible by direct shuttle from San José in about 2 hours.

The most productive birdwatching hours in Costa Rica are the first two to three hours after dawn, when bird activity peaks. Most species are most active in the early morning for feeding, singing, and territorial display. By mid-morning, activity drops significantly — especially during the hot midday hours in lowland forests. A second, shorter activity peak occurs in the late afternoon before sunset, particularly for raptors and frugivores. Planning birdwatching activities for 5:30 to 8:30 a.m. and 4:00 to 6:00 p.m. maximizes productive observation time.

Binoculars are indispensable for birding in Costa Rica. A pair with 8x magnification and 42mm objective lenses (8x42) offers an excellent balance between magnification and brightness suitable for both open habitat and dark forest understory. A field guide to Costa Rican birds is equally important. Garrigues and Dean's 'The Birds of Costa Rica' and Stiles and Skutch's classic 'A Guide to the Birds of Costa Rica' are the two primary references, with the Garrigues and Dean guide being more practical for field use due to its compact size and updated taxonomy.

Seasonally, the resplendent quetzal is best observed between January and May during the nesting period. Waterbirds at Palo Verde and the Tempisque wetlands peak from December through March. Migratory shorebirds concentrate in April and September. Sea turtles arrive on beaches from July through October on the Caribbean, attracting associated wildlife activity. For overall bird diversity, the transition months of November and December and the early dry season from December through February offer a combination of resident breeding activity and the arrival of North American migrants wintering in Costa Rica.
