Hummingbirds are found only in the Americas, ranging from Alaska to Chile. With over 300 species, they are the second largest family of birds after tyrant flycatchers. Their small size, jewel-colored plumage, and astonishing speed and maneuverability make them one of the most popular groups of birds. But which country can claim the most hummingbird species within its borders?
What are hummingbirds?
Hummingbirds are birds comprising the family Trochilidae. They are among the smallest of birds, with most species measuring in the 7.5–13 cm (3–5 in) range. Indeed, the smallest extant bird species is a hummingbird – the 5 cm bee hummingbird weighs less than 2 grams. They can hover in mid-air by rapidly flapping their wings 12–80 times per second. They can also fly backwards, and are the only group of birds able to do so. Their English name derives from the characteristic hum made by their rapid wing beats.
Where are hummingbirds found?
Hummingbirds are restricted to the Americas. The greatest species diversity is in South America, but there are also many species in Central America and about 12 species regularly breed in North America. Hummingbirds can occupy a broad range of habitats. As well as inhabiting disturbed urban and suburban habitats, they also occur in tropical rainforest, dry forest, second growth, and cloud forest. Some hummingbird species are adapted to alpine habitats high in the Andes Mountains, where their capacity for rapid oxygen consumption allows them to thrive in low-oxygen conditions that would cause other animal species to become exhausted.
Countries with the Most Hummingbird Species
Colombia
Colombia has the most hummingbird species of any country, with over 170 species recorded within its borders. This South American country’s terrain includes Amazon rainforest, highlands, coastal regions, and tropical islands, providing varied habitat able to support a wide diversity of hummingbirds. Endemic hummingbirds restricted to Colombia include the Buffy Helmetcrest, Gorgeted Puffleg, and Colorful Puffleg. Key locations to see hummingbirds in Colombia include Caneyes Los Pinos Bird Sanctuary near Bogota and Rio Blanco Nature Reserve in Manizales.
Ecuador
Ecuador is second only to Colombia when it comes to hummingbird species diversity, with more than 130 species recorded in the country. Although a relatively small nation, Ecuador has a wide variety of habitat types, from the coastal lowlands to the heights of the Andes Mountains. The varied landscape provides plentiful nectar for hummingbirds. Top spots for seeing hummingbirds in Ecuador include the cloud forests of Mindo and the Ecuadorian Amazon. Endemic species include the Violet-throated Metaltail and the Violet-tailed Sylph.
Peru
Peru boasts around 120 species of hummingbirds. As with Colombia and Ecuador, Peru offers a mix of habitats ranging from arid coastal regions to the peaks of the Andes Mountains and the lush Amazon Rainforest, supporting a rich variety of hummingbirds. Marvelous Spatuletail, a striking hummingbird with racquet-shaped tail feathers, is endemic to Peru. Key sites to observe hummingbirds include Machu Picchu, Abra Malaga in the Andes, and cloud forest areas around Cusco.
Brazil
The vast nation of Brazil is home to around 100 species of hummingbirds, placing it fourth in species numbers. Although Brazil lacks the Andes Mountains found in some neighboring countries, it does contain extensive tropical forests and grassland areas teeming with nectar-rich blooms to sustain hummingbirds. Planalto Hermit and Plovercrest are two hummingbirds restricted to Brazil. Excellent regions to see hummingbirds include the lush Atlantic Forests and the Pantanal wetlands.
Mexico
Mexico has recorded over 50 species of hummingbirds. While less than some South American nations, this is still an impressive diversity considering Mexico’s landlocked location in North America. Broad-billed Hummingbird and Berylline Hummingbird are among the hummingbirds endemic to Mexico. Important sites for observing Mexico’s hummingbirds include El Triunfo Biosphere Reserve and wildlife reserves along the Yucatan Peninsula.
Total Species Counts
| Country | Number of Hummingbird Species |
|---|---|
| Colombia | 170 |
| Ecuador | 130 |
| Peru | 120 |
| Brazil | 100 |
| Mexico | 50 |
As this table shows, Colombia has substantially more hummingbird species than any other nation with 170 species recorded within its borders. Ecuador and Peru follow with 130 and 120 species respectively. While Brazil’s diverse habitats host around 100 hummingbird species. Mexico’s tally of 50 species is still noteworthy given its geographic location.
Features that Support Hummingbird Diversity
Habitat Variety
Nations like Colombia, Ecuador, and Peru boast an exceptional range of habitat types including tropical forests, cloud forests, high-altitude grasslands, mountains, dry scrubland, wetlands, and coastal regions. This habitat diversity provides plentiful sources of nectar to sustain specialised hummingbird species.
Position on Migratory Route
Countries along the north-south migratory route of hummingbirds between North and South America typically host higher species numbers as they provide stopover habitat for migrants moving to and from wintering grounds.
Topographical Features
Nations with extensive mountain chains and highlands like the Andes provide varied elevational niches able to support different hummingbird species. High mountains also help intercept moisture and create rainfall to support flowering plants.
Geographic Extent
Larger countries are able to encompass greater habitat diversity and support more hummingbird species. Nations like Brazil and Colombia benefit in species totals from their expansive geographic area.
Climate Factors
A warm tropical climate with plentiful rainfall creates ideal conditions for flowering plants relied upon by hummingbirds for nectar. Abundant blooms support higher densities of hummingbird species.
Threats to Hummingbirds
Though hummingbirds remain widespread and abundant in many regions, they face increasing threats especially in Central and South America. These include:
Habitat Loss
Logging, agricultural expansion, development, and urbanisation can destroy or degrade hummingbird habitat, removing vital food sources.
Pesticides
Chemical use can reduce insect prey for hummingbirds and contaminate nectar sources.
Climate Change
Changing weather patterns may alter flowering cycles or allow disease vectors to expand, impacting hummingbird populations.
Unlawful Trade
Trafficking of hummingbirds for the pet trade or decorative purposes continues to threaten some species.
Introduced Species
Invasive species can jeopardise native hummingbirds through resource competition, hybridisation, or disease transmission.
Conclusion
Colombia stands apart as the country with the most hummingbird species, thanks largely to its diverse range of habitats from tropical lowlands to high-altitude Andes cloud forest. Neighboring Ecuador and Peru also harbour exceptional hummingbird diversity. While hummingbird numbers remain robust in many regions, increasing threats point to the need for habitat protection and international cooperation to safeguard these unique birds into the future. Looking after the plants that provide their nectar sources will be key.
