Costa Rica is a compact country with an unusually large birdwatching range. Depending on the source and species count used, national totals cited by Costa Rican tourism and conservation agencies range from 850 to 925 bird species. The same guides identify 52 hummingbird species, 167 aquatic bird species, and major seasonal movements of more than 3 million birds of prey through the Caribbean region.

At a glance
The following figures give a concise overview of the country’s birdwatching scale. They come from the named ICT tourism guides and SINAC conservation sources, which do not all use the same national baseline.
| Measure | Figure | Source or scope |
|---|---|---|
| Bird species | 925 | ICT Bijagua Tourist Guide |
| Bird families | 89 | ICT Bijagua Tourist Guide |
| Hummingbird species | 52 | ICT Bijagua Tourist Guide |
| Aquatic bird species | 167 | ICT Bijagua Tourist Guide |
| Bird species described | 850 | SINAC Wildlife page |
| Bird species in ACOPAC | 746 | SINAC ACOPAC |
| Bird species in Tortuguero National Park | 442 | SINAC Tortuguero NP |
| Seasonal raptors through the Caribbean | More than 3 million | ICT Caribbean Tourist Guide |
These are not interchangeable measurements. A national species total is different from a count recorded in one conservation area, while a seasonal migration figure measures birds passing through a route rather than resident species. Keeping those distinctions clear is essential when interpreting Costa Rica birdwatching statistics.
National bird diversity
The ICT Bijagua Tourist Guide cites 925 bird species in Costa Rica, along with 89 bird families. It also lists 76 endemic bird species and 93 regional endemic bird species. In the same guide, hummingbirds account for 52 species and aquatic birds for 167 species. Together, those figures show why a birding trip can include very different ecological groups rather than a narrow selection of familiar forest birds.
Another ICT source gives a closely related national figure: the Turrialba birdwatching guide cites 924 bird species, 89 families, 167 aquatic species, and 52 hummingbird species. It also lists 75 bird-of-prey species, 93 regional endemic species, and 7 local endemic species. The one-species difference between the Turrialba and Bijagua totals should be treated as a source-specific count, not as a measured annual change.
SINAC’s Wildlife page presents a lower figure of 850 bird species described. That page also reports more than 8,500 described plant species, 220 reptile species, 160 amphibian species, and 205 mammal species. It says Costa Rica has about 5% of the species described worldwide. These numbers provide a broader biodiversity context, but they use the page’s own description and should not be combined arithmetically with the ICT guide totals.
The ICT OSA Cultural Tourist Guide states that Costa Rica’s bird species constitute 9% of the world’s known species. The ICT Northern Plains Tourist Guide describes Costa Rica as one of the countries with the most bird species and habitat types in the world relative to its territory size. The ICT Bijagua Tourist Guide likewise describes the country as a favorite destination for naturalists and birdwatchers. Those descriptions help explain the appeal of Costa Rica outdoors, while the numeric totals indicate the scale of the opportunity.
Endemic and specialist birds
Endemism is one of the clearest ways to distinguish a general bird list from a Costa Rica-focused birdwatching experience. The ICT Bijagua Tourist Guide reports 76 endemic bird species and 93 regional endemic bird species. The Turrialba guide repeats the 93 regional endemic figure and adds 7 local endemic species. Because “endemic,” “regional endemic,” and “local endemic” describe different geographic scopes, these categories should not be added together.
The same tourism guides identify 52 hummingbird species. Hummingbirds therefore form a substantial specialist group within the national bird totals. The guides also cite 167 aquatic bird species, a category that points toward wetlands, rivers, coastal habitats, marshes, and other water-associated environments. The Turrialba guide lists 75 bird-of-prey species, adding a raptor-focused dimension to the country’s birdwatching profile.
The Caribbean Plains and Marshes Important Bird Area has species diversity above 400 species, according to the ICT Caribbean Tourist Guide. That Important Bird Area is also described as a highly important migratory corridor for at least 185 migratory species. The same guide identifies at least 5 species in the Caribbean area as endemic to the Central American Caribbean and 9 species as endemic to the highlands of Costa Rica and western Panama.
These figures describe overlapping ecological and geographic lenses. A bird may belong to a family, a feeding guild such as aquatic birds or raptors, and a geographic category at the same time. For visitors, the practical implication is that habitat choice changes the kinds of statistics—and birds—most relevant to a day in the field.
Migration through the Caribbean
Costa Rica’s Caribbean lowlands are especially notable for migration. The ICT Caribbean Tourist Guide reports that 3 million migratory birds of prey pass through Costa Rica from August to November. It separately describes more than 3 million birds of prey passing through the Caribbean region in a single season, and says those migrating raptors belong to 17 species.
The same guide identifies the central Caribbean coastal plains as a major migratory corridor from August to November. It describes the Caribbean lowlands as the second-largest migratory path on the planet and reports that the area has recorded more than 3,000 Peregrine Falcons during the fall migration season. These figures refer to movement through a route during a season, not to the number of resident raptor species in Costa Rica.
The ICT guide also says Costa Rica is one of five global bird migration hotspots. In its broader description of global migration hotspots, it reports more than 1 million birds per season. That statement has a wider hotspot context, while the Caribbean figures are specifically tied to Costa Rica’s regional migration corridor. The geographic distinction matters when comparing the numbers.
The August-to-November period is therefore the clearest seasonal window in the supplied migration statistics. During that interval, the Caribbean plains and marshes combine a high-diversity Important Bird Area with a corridor used by at least 185 migratory species. The result is a different birdwatching pattern from a species inventory: the emphasis is on timing, passage, and observation of movement at scale.
Conservation areas and bird counts
Regional counts show how much of Costa Rica’s bird diversity can be concentrated in protected landscapes. SINAC ACOPAC reports 746 bird species in the ACOPAC conservation area. The same source says those 746 species represent 83.6% of the 892 bird species set for Costa Rica in that source. This percentage is a source-specific comparison and uses the 892-species national baseline cited by SINAC ACOPAC.
ACOPAC also contains 16 of Costa Rica’s 34 most important watersheds, 11 of the country’s 12 life zones, 7 of 9 ecological transitions, and 6 altitude bands in Costa Rica’s national division. Those landscape figures help explain why its bird count is so high: the area spans multiple environmental conditions rather than one uniform habitat.
The SINAC Tortuguero Conservation Area reports 309 bird species, while SINAC Tortuguero National Park reports 442 bird species. These are different geographic designations and should be read as separate source-reported counts. The larger national-park figure is not evidence that the conservation area count is incorrect; it reflects the scope and accounting used by each source.
The SINAC ACG source estimates approximately 235,000 species in the ACG conservation area. It says that estimate equals 65% of the estimated species in Costa Rica and that ACG represents 2.6% of global biodiversity. ACG is one of 11 conservation areas in SINAC. Those figures concern total biodiversity across taxonomic groups, not bird species alone, so they provide context rather than a bird checklist.
Habitats behind the numbers
ACOPAC’s wider biodiversity figures illustrate the habitat richness associated with its 746 bird species. SINAC ACOPAC reports more than 14,000 lepidoptera species, 11 of Costa Rica’s 18 endemic freshwater fish species, and 5,640 plant species. The source says those plants equal 62.7% of Costa Rica’s national total cited there and that ACOPAC hosts 60% of Costa Rica’s flora.
The same source reports about 10,000 endemic species overall in Costa Rica and 5,000 endemic species in ACOPAC. It says more than 76% of timber species in ACOPAC are in danger of extinction. It also records 201 of Costa Rica’s 238 mammal species, 4 primate species reported for Mesoamerica, and 6 species of big cats. ACOPAC is described as hosting more than 70% of Costa Rica’s mammals, birds, and lepidoptera.
These conservation statistics do not turn directly into a bird total, but they show the biological setting in which birdwatching takes place. Diverse plant communities, freshwater systems, elevation bands, and ecological transitions create multiple opportunities for different bird groups. The sources also make clear that biodiversity richness exists alongside conservation pressure.
The ICT Turrialba guide cites 53% forest covering in the broader region. It also says 365/24/7 birdwatching is possible in the route area. The 53% figure describes forest cover in the broader region, while the 365/24/7 statement describes year-round, around-the-clock availability of birdwatching opportunities; neither should be interpreted as a claim that every bird species is visible at every time.
The Osa guide identifies 29 national parks tied to its birdwatching route material. That route context, together with the Caribbean corridor, Turrialba’s forest landscape, ACOPAC’s habitat coverage, and Tortuguero’s reported bird counts, shows why Costa Rica birdwatching statistics are best read geographically. National totals describe the country’s overall range; regional counts identify concentrated diversity; and migration figures describe seasonal movement through particular landscapes.
