Birds are a popular type of pet for many people. There are numerous species that have been domesticated over the years to live in close proximity with humans. When it comes to determining the most common domestic bird, there are a few leading contenders.
Chickens
One of the clear frontrunners for most common domestic bird is the chicken. The chicken has a long history of domestication stretching back thousands of years. There are records of chickens being kept as far back as 4000 BC in China. Over the centuries, keeping chickens for their eggs and meat became incredibly common worldwide.
Today, chickens remain one of the most numerous domesticated animals on the planet. According to the Food and Agriculture Organization, there are over 23 billion chickens being farmed for meat and eggs globally as of 2019. The chicken population absolutely dwarfs other domesticated species.
The traits that make chickens suitable for domestication include:
- They mature quickly, being ready for harvest in just 6-8 weeks
- Chickens are omnivores and not picky eaters, they can live off scraps and foraging
- They are small birds that don’t require much space
- Chickens have a strong egg laying capacity, producing eggs almost daily
- They exhibit behaviors like roosting that make containing them easy
Based solely on their enormous global population and history of close coexistence with humans, chickens have a strong claim to being the most common domestic bird.
Ducks
Another extremely widespread domesticated bird is the duck. Many different duck species have been raised by humans, with the most popular being the Pekin duck. There is evidence of ducks being domesticated in ancient Egypt 4000 years ago.
Ducks offer benefits like:
- Meat production, ducks grow fast and have tasty meat
- Egg laying, though not at the rate of chickens
- Pest control, ducks eat slugs, snails, and other garden pests
- Manure production to fertilize gardens
Globally, FAO estimates there are over 1.2 billion ducks being raised domestically. The vast majority are in Asia where duck farming has historically been centered. China alone produces over 4 billion kg of duck meat annually. While they lag far behind chickens in numbers, ducks still have a widespread global population.
Pigeons
An often overlooked but highly numerous domestic bird is the humble pigeon. Rock pigeons have lived alongside humans for millennia. Archaeological evidence indicates they were domesticated as far back as 10,000 years ago in the Middle East.
Pigeons were historically raised for food as squab (young pigeon) meat. But they also proved adept at carrying messages and racing. Unique attributes of pigeons include:
- Homing ability – they can return to their roost from remarkable distances away
- Swift flight – pigeons can achieve very high speeds in flight
- Prolific breeding – females can hatch up to 8 broods per year
The global population of domestic pigeons is challenging to quantify. However, their populations number in the hundreds of millions globally based on estimates of racing and fancy pigeons alone. When factoring in birds raised for meat, the total pigeon population likely only trails chickens and ducks.
Turkeys
The turkey is another bird with a long history of domestication. They were first raised by Aztec and Mayan civilizations thousands of years ago. The Spanish brought them back to Europe from the Americas in the 16th century.
Turkeys are farmed for their delicious meat. Key attributes include:
- Rapid growth – turkeys grow from poults to 30 lbs in just 4-5 months
- Docile temperament – turkeys are very calm and timid by nature
- Efficient feed conversion – turkeys convert feed to muscle mass efficiently
There are approximately 465 million turkeys being raised globally according to FAO, predominantly in North America and Europe. Their high meat yield and growth rate make turkeys a globally significant domesticated bird.
Geese
Geese round out the top domesticated waterfowl species. Evidence suggests Egyptians may have kept geese as early as 3000 BC. The ancient Romans also raised geese and discovered their value as guard animals.
Benefits of domestic geese include:
- Weed control – geese are voracious grazers and eat weeds
- Meat and eggs – geese can be raised for both
- Feathers and down – geese produce fine feathers used in pillows, comforters, etc
- Security – geese make loud calls at disturbances and intruders
Global domestic goose populations are estimated at over 700 million. China, Africa, and Europe have the largest concentrations of geese. Though they don’t receive the same attention as chickens, ducks, and turkeys, geese are still raised in abundance worldwide.
Comparison of Global Populations
To summarize and compare the global population estimates for major domesticated bird species:
Bird | Global Population Estimate |
---|---|
Chickens | 23 billion |
Ducks | 1.2 billion |
Pigeons | 100s of millions |
Turkeys | 465 million |
Geese | 700 million |
As the table shows, chickens wildly outnumber all other domesticated birds by billions. Ducks and geese occupy the next tiers, followed by turkeys. Pigeons also likely number in the hundreds of millions, though harder to precisely quantify.
Key Takeaways
In summary, the review of the most common domesticated bird species leads to the following key conclusions:
- Chickens are the overwhelmingly most populous domesticated bird with over 23 billion globally.
- Ducks, geese, turkeys, and pigeons are the next most abundant domesticated birds.
- Waterfowl like ducks and geese have been domesticated for thousands of years alongside chickens.
- Pigeons have an extremely lengthy history of domestication and very large global populations.
- Turkeys were domesticated in the Americas and now number close to half a billion worldwide.
- Cultural significance and economic incentives are major drivers maintaining massive populations of the major domesticated birds.
So while several species vie for the title and have compelling cases, chickens stand in a league of their own as the undisputed most common domestic bird in the world based on overwhelming population sizes.
Conclusion
Examining the evidence makes it abundantly clear that the chicken is the hands-down most common domesticated bird species on the planet. With a global population exceeding 23 billion, chickens outnumber their nearest competitor, ducks, by over 20 billion as of current estimates.
The staggering scale of the chicken’s global domination is driven by its importance as source of meat and eggs. Additionally, chickens possess numerous traits that favor domestication like rapid growth rates, omnivorous diet, and abilities to produce eggs prolifically.
Other domesticated birds like ducks, geese, turkeys, and pigeons have much smaller, though still substantial, populations in the hundreds of millions to billions. But none come remotely close to matching the ubiquity of the chicken.
Based on the overwhelming evidence, the chicken has no peer when it comes to the title of world’s most common domesticated bird. From its ancient roots in Asia to modern factory farms housing tens of thousands, the chicken is far and away the leader when it comes to domesticated bird populations.
