House sparrows are small, energetic birds found almost everywhere humans live. They belong to the Passeridae family and are scientifically named Passer domesticus. The name “house sparrow” comes from their close association with human settlements, where they build nests in houses and other structures. Swedish naturalist Carl Linnaeus first described them in 1758. They’re native to Europe, Asia, and North Africa but have spread worldwide through human introduction.

Habitat:
House sparrows thrive in urban and suburban areas. They’re commonly found near farms, towns, and cities where humans provide food and shelter. They’re also adaptable to parks, gardens, and open countryside.
Died/Food:
House sparrows are omnivores. They mainly eat grains, seeds, and crumbs from human food. They also consume insects, especially during the breeding season when they need extra protein for their chicks.
Nesting:
House sparrows build nests in crevices, roofs, walls, tree holes, or birdhouses. They use materials like grass, feathers, paper, and string to create a soft lining. Females lay 3–7 eggs per clutch, and both parents take turns incubating them. The chicks hatch in about two weeks and leave the nest after another two weeks.
Behaviour:
House sparrows are very social birds and live in large flocks. They’re known for their boldness around humans and often feed near people without fear. They can be noisy and territorial, sometimes competing aggressively with other birds for food and nesting sites.
House Sparrow Lifespan:
In the wild, house sparrows live around 3–5 years, although some can live up to 10 years. In captivity, where predators and food shortages aren’t an issue, they can live longer.
House Sparrow Facts:
- World’s Most Common Bird: House sparrows are one of the most widespread bird species, living on every continent except Antarctica.
- Historical Records: Ancient Romans mentioned house sparrows in their writings, and they were often associated with love and fertility in Roman mythology.
- Introduced Species: House sparrows were intentionally introduced to the Americas in the 1850s to control insect populations.
- Lifespan Record: The oldest recorded wild house sparrow lived for 13 years and 4 months, an impressive feat for such a small bird.
- Feather Care Experts: Sparrows take dust baths to remove excess oil and parasites, an unusual but effective grooming habit.
- Global Population: There are over 500 million house sparrows worldwide, but their numbers are declining in some regions due to habitat loss.
- Fossil Evidence: Fossils of sparrows dating back 100,000 years have been found, proving their long-standing presence on Earth.
- Weather Forecasters: Sparrows chirp more during clear weather, almost acting as tiny barometers.
- Community Birds: They rarely live alone and prefer the company of large flocks for safety and social interaction.
- Famous Incident: In 1958, during China’s “Four Pests Campaign,” sparrows were nearly wiped out because they were blamed for eating crops. This caused a massive locust infestation, proving their importance in balancing ecosystems.
FAQ’s about House Sparrows:
Are house sparrows rare?
No, house sparrows are not rare. They are one of the most common birds in the world, found on every continent except Antarctica. However, their numbers are declining in some areas due to habitat loss and pollution.
What are the predators of house sparrows?
House sparrows have many predators, including hawks, owls, cats, snakes, and larger birds like crows. Nestlings and eggs are especially vulnerable to predators.
Where do you find house sparrows? (Where do they live?)
House sparrows live almost everywhere humans do—cities, towns, farms, and even villages. They prefer areas with plenty of buildings, trees, or shrubs for nesting and easy access to food.
Do house sparrows migrate?
House sparrows don’t usually migrate. They stay close to their homes year-round, relying on their adaptability to survive in changing weather.
Why are house sparrows considered exotic pets?
Although house sparrows are common, they can be seen as exotic pets because they aren’t traditional pet birds like parrots. Their cheerful chirps, small size, and easy care make them appealing to some people.
What do house sparrows like to eat?
House sparrows love to eat seeds, grains, and crumbs. They also eat insects, especially during breeding season, to feed their chicks.
Are house sparrows social birds?
Yes, house sparrows are very social. They live in groups, roost together, and communicate constantly with chirps and calls. They’re also comfortable around humans, often eating near us or building nests in our buildings.
How long do house sparrows live?
In the wild, house sparrows live about 3-5 years. In captivity, with good care, they can live up to 10 years.
What can I feed my pet house sparrows at home?
We can feed pet house sparrows birdseed, millet, sunflower seeds, small grains, and fresh fruits like apples and berries. They’ll also appreciate some mealworms or cooked rice as a treat.
How much weight can a house sparrow carry in flight?
House sparrows are small birds, so they can carry only very light objects, usually no more than a few grams, like bits of food or nesting material.
What would happen if house sparrows went extinct?
If house sparrows went extinct, the balance of ecosystems could be disrupted. These birds help control insect populations and spread plant seeds. Their absence might lead to an increase in pests and changes in vegetation growth. Additionally, many animals that prey on house sparrows, like hawks or cats, would lose a food source.
Can house sparrows swim?
House sparrows can’t swim like ducks, but they’re capable of paddling if they accidentally fall into water. They usually avoid water deeper than what’s needed for a quick bath.
Are there different types of house sparrows?
Yes, there are several subspecies of house sparrows, but they all belong to the species Passer domesticus. These subspecies look slightly different depending on where they live but are generally very similar.
What do house sparrows dislike?
House sparrows dislike strong odors, loud noises, and aggressive birds that invade their space. They’re also cautious around predators like hawks and cats.
Can we pet house sparrows?
In some places like the USA, house sparrows are not protected because they are considered invasive species, so it’s legal to keep them as pets. In the EU, house sparrows are usually protected by wildlife laws, so keeping them as pets might require special permits. Wherever we live, it’s important to check local laws and ensure that caring for a house sparrow doesn’t harm them or the wild population.
