Introduction: What Are Scientific Names of Birds?
Every bird on Earth — from the majestic Bald Eagle soaring over North America to the vibrant Peacock displaying its feathers across Indian gardens — has two identities: the common name used in everyday life and a scientific name that is recognised identically in every country, every language, and every century.
Birds are some of the most beautiful and fascinating creatures in the world, and each species has its own unique scientific name. These names may sound complex, but they help scientists clearly identify and study different birds without confusion.
It is important for birdwatchers, as well as ornithologists and conservationists, to know the scientific names of bird species. These names certainly provide a clear global standard for identifying birds, which is essential for their studies, monitoring, and conservation.
All birds have a scientific name — actually two names — derived primarily from Latin or Greek. Anas platyrhynchos is the scientific name for the Mallard. Anas, the genus, is Latin for duck, indicating that the Mallard is related to other ducks such as the Pintail, Gadwall, and Black Duck. The species name, platyrhynchos, is Greek for flat bill, referring to the typical duck-like bill.
In this guide, you’ll find a complete list of scientific names of common birds organised by category — Indian birds, birds of prey, waterbirds, songbirds, flightless birds, parrots, and national birds — along with Latin meanings, the classification system, and an exam-ready quick reference.
What Is the Scientific Name of Birds (Class)?
In Linnaean taxonomy, birds are categorised as the biological class Aves. Hence, the class name for all birds is Aves. Birds, Class Aves, are arranged into groups called Orders (ending in -iformes) — such groups as the ducks and geese, loons, hawks and eagles, hummingbirds, kingfishers and rollers, herons and egrets, and penguins. The largest group, Passeriformes, is the songbirds. In each Order are Families, ending in -idae.
The Two Parts of a Bird’s Scientific Name
| Part | What It Represents | Example |
|---|---|---|
| Genus (first word) | The broader group of closely related birds | Pavo |
| Species (second word) | The specific bird within that genus | cristatus |
| Full scientific name | Genus + Species together | Pavo cristatus (Peacock) |
Rules for Writing Bird Scientific Names
- The genus name always begins with a capital letter — Pavo
- The species name is always entirely lowercase — cristatus
- Both parts are written in italics when typed — Pavo cristatus
- Both parts are underlined when handwritten — <u>Pavo cristatus</u>
- After first mention, the genus can be abbreviated — P. cristatus
- Scientific names follow binomial nomenclature (genus + species) and provide precision across languages and borders. Names often describe appearance, behaviour, habitat, or honour people — though recent American Ornithological Society decisions are phasing out eponymous names tied to problematic histories in favour of descriptive ones.
Bird Classification Hierarchy — Worked Example
Birds are organised into groups by scientific classification, based upon their anatomical structure, geographic distribution, behaviour, blood proteins, and a variety of other characteristics. Most recently, and probably most accurately, DNA hybridisation has determined the relationships and supposed evolutionary history of all the bird groups of the world and most of the species.

Frequently Asked Questions
1. What is the scientific name of birds as a class?
The scientific name for all birds as a class is Aves. Every bird species on Earth belongs to Class Aves, which is further divided into Orders (ending in -iformes), Families (ending in -idae), Genus, and Species.
2. Who invented the scientific naming system for birds?
The binomial nomenclature system used to name birds was invented by Carl Linnaeus, a Swedish botanist and zoologist. Scientific names are created using a system called binomial nomenclature, which includes the genus name followed by the species name. Linnaeus formally published his system in Systema Naturae in 1758 for animals, including birds.
3. What is the scientific name of the Peacock?
The scientific name of the Indian Peacock — India’s national bird — is Pavo cristatus. Pavo is the Latin word for peacock, and cristatus means crested, referring to the peacock’s iconic crown of feathers.
4. What is the scientific name of the House Sparrow?
The scientific name of the House Sparrow is Passer domesticus. Passer means sparrow in Latin, and domesticus means of the house or domestic — reflecting the bird’s close association with human settlements worldwide.
5. What is the scientific name of the Eagle?
The most well-known eagle scientific names are: Bald Eagle — Haliaeetus leucocephalus (white-headed sea eagle); Golden Eagle — Aquila chrysaetos (golden eagle in Greek); and Indian/Steppe Eagle — Aquila nipalensis (from Nepal). Aquila is Latin for eagle and is one of the most recognisable bird genera globally.
6. Can scientific names of birds change?
Yes, names can change when scientists discover new information about a bird’s classification or genetic relationships. Recent American Ornithological Society decisions are phasing out eponymous names tied to problematic histories in favour of descriptive ones, reflecting broader efforts toward equity and clarity. DNA analysis has also led to significant reclassifications in recent decades.
7. What is the scientific name of the Ostrich?
The scientific name of the Ostrich is Struthio camelus. Struthio comes from the Greek word for ostrich, and camelus means camel in Latin — a reference to the ostrich’s long neck and ability to survive in arid desert conditions similar to a camel’s habitat.
8. How many bird species exist in the world?
As of 2026, scientific databases like Avibase track approximately 10,000 to 11,000 living species of birds. However, recent morphological and genetic studies suggest that if we redefine species based on evolutionary lineages, that number could be as high as 18,000 to 20,000.
9. What is the scientific name of the Owl?
Different owl species have different scientific names. The Barn Owl is Tyto alba (alba = white). The Great Horned Owl is Bubo virginianus (from Virginia). The Snowy Owl is Bubo scandiacus (from Scandinavia). The Spotted Owlet found across India is Athene brama (brama from the Sanskrit reference to Brahmin/India).
10. Why are bird scientific names written in Latin or Greek?
All birds have a scientific name — actually two names — derived primarily from Latin or Greek. Latin was the universal language of science and scholarship when Linnaeus established the naming system in the 18th century. Being a dead language, Latin meanings remain fixed over time — unlike living languages where words change meaning — ensuring bird scientific names remain stable and universally understood across all countries and centuries.
Final Thoughts
Scientific names of birds are the universal passport of ornithology — giving every one of the world’s 10,000+ bird species a unique, precise, and permanent identity that transcends language, geography, and time. From the iconic Pavo cristatus displaying its crown in an Indian garden to the critically endangered Ardeotis nigriceps fighting for survival on the Rajasthan plains, every scientific name tells a story about a bird’s appearance, behaviour, habitat, or discovery history.
Learning these names helps with accurate bird identification, education, research, and understanding biodiversity. From forests to oceans, every species has its own unique identity. Once you understand the system — genus reveals the family, species identifies the individual, italics signal the scientific name — reading and remembering these names becomes second nature.
