Costa Rica is listed among the world’s top five favorite birding countries, with more than 900 bird species recorded in tourism information from the Costa Rican Tourism Institute (ICT). The same material describes a National Bird Route with 12 main sites, four Bird Zones, and seven National Parks, giving travelers a measurable framework for exploring the country’s birdlife.

Costa Rica birding at a glance
The CARIBE Tourist Guide, published by ICT, describes Costa Rica as a country with 51,100 square kilometers of land and 589,000 square kilometers of territorial sea. Within that geography, the guide describes more than 900 bird species and says Costa Rica’s bird species constitute 9% of the world’s known bird species.
The birdlife map in the same ICT guide lists 924 bird species, 52 hummingbird species, and 93 endemic regional bird species. These figures are map and guide counts, so they should be read as the counts presented by that source rather than as a single standardized scientific inventory.
| Indicator | Figure | Source label |
|---|---|---|
| Land area | 51,100 km² | CARIBE Tourist Guide / ICT |
| Territorial sea | 589,000 km² | CARIBE Tourist Guide / ICT |
| Bird species described | More than 900 | CARIBE Tourist Guide / ICT |
| Bird species on the birdlife map | 924 | CARIBE Tourist Guide / ICT |
| Hummingbird species on the map | 52 | CARIBE Tourist Guide / ICT |
| Main National Bird Route sites | 12 | CARIBE Tourist Guide / ICT |
The National Bird Route is organized into four Bird Zones and includes seven National Parks plus one National Wildlife Refuge. The route therefore links species observation with a network of protected and managed landscapes rather than concentrating birding tourism in one destination.
Species richness and endemism
The CARIBE Tourist Guide / ICT identifies 19 globally threatened bird species in Costa Rica. It also describes seven endemic bird species: four on the mainland and three on Cocos Island. The distinction matters for trip planning because mainland routes and the isolated island environment represent different geographic contexts.
The same guide divides Costa Rica’s birdlife zones among humid tropical forest, humid tropical forest of the South Pacific, dry tropical forest, and highlands. That division helps explain why a relatively compact country can offer different birding conditions across Caribbean lowlands, Pacific wetlands, southern rainforest, and mountain habitats.
Several destination counts illustrate the range of local coverage:
- The Caño Negro node has 377 bird species and two endemic bird species, according to the CAÑO NEGRO Tourist Guide / ICT.
- Palo Verde National Park has 343 bird species, according to the SOUTH Guanacaste Tourist Guide / ICT.
- The Osa bird guide lists 492 bird species and 16 endemic bird species, according to the Osa Tourist Guide / ICT.
- Corcovado National Park is described as protecting 465 bird species and 20 regional endemic species in the guide’s summary counts, according to the Osa Tourist Guide / ICT.
- Braulio Carrillo National Park has around 515 bird species, according to the ICT Braulio Carrillo brochure.
These figures are destination-specific guide counts. They should not be added together, because the areas overlap in regional species and the guides use different summary scopes.
Migration and the National Bird Route
Migration is one of the clearest seasonal dimensions of Costa Rica birding tourism. The CARIBE Tourist Guide / ICT says that 3 million migratory birds of prey fly through Costa Rica from August to November. It also identifies 220 migratory species corresponding to Nearctic migrants from North America.
The National Bird Route contains 12 nodes or main birding sites. Its four Bird Zones connect habitats that differ in elevation, rainfall, vegetation, and wetland structure. For visitors, the route’s numerical structure is useful because it frames Costa Rica as a multi-region birding destination, while the migration figures point to August through November as an explicitly measured passage period for migratory birds of prey.
The Caribbean Plains and Marshes Important Bird Area (IBA) has species diversity greater than 400 species and is a migratory corridor for at least 185 migratory species, according to the CARIBE Tourist Guide / ICT. The guide gives the same minimum of 185 migratory species for the Tortuguero corridor.
Tortuguero is divided into two large sectors with distinct habitats and altitudinal ranges. The Tortuguero Plain reaches altitudes of up to 311 meters above sea level. The ICT Tortuguero National Park brochure says the park has over 440 bird species and that aquatic-bird habitat is abundant along the waterways.
For visitors comparing trail scale within the park, the ICT brochure lists a 2-kilometer trail to the Jaguar sector, a 2-kilometer Tortuguero River Canal trail, and a Jaguar trail of 4,290 meters. The same Jaguar trail is also listed as 14,075 feet in the brochure; those are two supplied length expressions for the same trail, not separate trails.
Wetlands and Caribbean birding
Tortuguero National Park is fully located in the El Parque Nacional Tortuguero / Northeastern Caribbean Wetland, which the ICT brochure describes as Costa Rica’s largest wetland. The combination of waterways, lowland forest, and migratory connectivity makes Tortuguero a particularly important example of how habitat and tourism infrastructure intersect.
Caño Negro provides another wetland-centered birding profile. The CAÑO NEGRO Tourist Guide / ICT reports that the Caño Negro Mixed National Wildlife Refuge is about 10,000 hectares. Caño Negro includes one National Park and two wildlife refuges. It was declared a RAMSAR site on December 27, 1991, and became a core area of the Agua y Paz Biosphere in 2007.
The same guide gives two different summary scales for Caño Negro: the node has 377 bird species, while Caño Negro is also described as supporting more than 500 bird species. These figures are retained as source-specific descriptions rather than combined or treated as one standardized total.
Caño Negro’s more specialized figures include six species of kingfishers, the country’s largest colony of cormorants, and the only region with permanent populations of the Nicaraguan grackle. The guide also calls it an important year-round site for the Nicaraguan seed finch. These statements identify resident and seasonal interest without assigning unsupported visitor totals.
Pacific and Guanacaste birdwatching
Palo Verde National Park is a prominent wetland statistic in the SOUTH Guanacaste Tourist Guide / ICT. The park has 343 bird species, and its birds represent 37% of Costa Rica’s total avifauna. Wetlands cover 60% of the park, while birdwatching can peak at 250,000 individuals in the rainy season.
The 250,000 figure describes birds observed or present at the peak of the rainy season, not tourist arrivals. Keeping that distinction clear is important when interpreting birding tourism statistics: habitat counts, species counts, and visitor counts measure different things.
The same guide lists Isla de Pájaros at 2.3 hectares. Its small area contrasts with the scale of the surrounding birding landscape and shows why individual islands, wetlands, and protected sites can matter even when their land area is limited.
The Arenal Tempisque Conservation Area adds a broader landscape comparison in northern and northwestern Costa Rica. The NORTHERN Plains Tourist Guide / ICT reports that ACAT covers 395,046.14 hectares, equal to 7.73% of Costa Rica’s national territory. Almost 25% of ACAT is protected wildlife area, and another 29% consists of biological corridors.
ACAT spans eight different life zones. The guide also says it includes six species of wild cats found in Costa Rica and about 190 plant species endemic to Costa Rica. Those are not bird counts, but they quantify the ecological breadth supporting wildlife-focused travel around the conservation area.
Northern highlands and central forests
Monteverde is one of the highland examples in the NORTHERN Plains Tourist Guide / ICT. The guide says Monteverde contains 70 of the 103 tree families reported for Costa Rica and 21.23% of Costa Rica’s orchid species. These figures provide context for a forest structure that supports observation beyond birds, while the ICT birdlife framework places highlands among the country’s four broad birdlife zones.
Braulio Carrillo National Park supplies another central-forest benchmark. The ICT Braulio Carrillo brochure gives the park’s area as 123,394 acres and says it is home to around 6,000 plant species and large trees. It lists around 515 bird species and two trails, Las Palmas and El Ceibo.
The scale of Braulio Carrillo’s plant diversity and bird count helps explain why forest destinations are central to Costa Rica’s birding profile. The figures describe ecological resources, not the number of guided tours or visitors, so they are best used to compare destination habitat potential.
Barbilla National Park is another Caribbean-side site documented by the ICT Caribe guide. It is 25 kilometers east of Turrialba, while its main entrance is 3 kilometers east of Siquirres on the road to Limón. The road from the entrance to the park is 16 kilometers long.
The same guide records about 3,500 to 4,000 millimeters of annual rainfall at Barbilla, about 5,000 species of vascular plants, and 1,000 to 2,000 species of non-vascular and lesser species. The rainfall range and plant counts describe the habitat conditions behind rainforest birding, but the supplied Barbilla figures do not include a bird-species total.
Osa Peninsula and southern biodiversity
The Osa Peninsula is represented by some of the largest bird and biodiversity figures in the supplied ICT tourism guides. The Osa Tourist Guide / ICT lists 492 bird species for Osa and 16 endemic bird species. It describes Corcovado as protecting 140 mammal species and 465 bird species, with 20 regional endemic species in the guide’s summary counts.
Osa receives around 6,000 millimeters of annual precipitation, according to the Osa Tourist Guide / ICT. The same guide says the Osa Peninsula holds 2.5% of global biodiversity and more than 50% of Costa Rica’s biodiversity. These are broad guide-level biodiversity statements, while the rainfall figure is an annual precipitation estimate for the peninsula.
The Osa figures show why southern rainforest birding is often treated as a distinct destination experience: the area combines a 492-species peninsula count with a 465-species Corcovado count, endemic-species measures, and very high annual rainfall. As with the other destination totals, these counts should be read within each guide’s stated geographic scope rather than summed into a national total.
For visitors building a Costa Rica Outdoors itinerary, the statistics point to several complementary choices: migration-focused Caribbean wetlands, rainy-season concentrations at Palo Verde, highland forests around Monteverde, central forest trails in Braulio Carrillo, and the exceptionally biodiverse Osa Peninsula. The National Bird Route’s 12 nodes and four Bird Zones provide the country-level structure, while the individual ICT guides supply the destination-level measurements.
