The house sparrow (Passer domesticus) is a small, highly successful bird.

It belongs to the sparrow family known as Passeridae. This species is one of the most widely distributed wild birds on Earth. This is because they were introduced to many regions by humans. They can be found in parts of Australasia, Africa, and the Americas. They are most commonly associated with human habitation. This means they live near people in urban or rural settings.

They generally avoid habitats like deep woodlands, grasslands, or hot, dry deserts.

Physically, the house sparrow is a compact bird with a full chest.

They have a large, rounded head and a stout, conical bill. This strong bill is an adaptation for eating hard seeds. A typical length is about 14 to 17 centimeters. Their mass usually ranges between 24 and 42 grams. The sexes show strong sexual dimorphism, meaning they look quite different. Males have bright black, white, and brown markings. Females and young birds are much more plain. They are mostly colored in shades of pale brown and grey.

The male's plumage is quite complex and colorful.

He has a dark grey crown on top of his head. He also has chestnut brown markings on the sides of his crown. A black patch appears around his bill and on his throat. This throat patch is often called a "bib" or a "badge." Scientists believe the size of this badge might signal social status. The male's underparts are pale grey or white. In contrast, the female has no black markings or grey crown. She has a distinct pale supercilium, which is a stripe above the eye. Her upperparts are brown with darker streaks.

House sparrows are opportunistic omnivores, which means they eat many things.

Their natural diet consists of seeds from grains, weeds, and flowering plants. However, they also hunt for invertebrates. This includes insects, larvae, and caterpillars. They are very good at finding food near people. You might see them feeding at public bird feeding stations. This flexible diet helps them survive in many different environments. They can thrive wherever food and shelter are available.

Communication is vital for these social birds.

They use many different vocalizations to interact. A short, frequent chirping call is used as a contact call. This helps birds in a flock stay together while resting. Males use a repetitive "ecstatic call" during the breeding season. This sounds like a song and helps them claim a nest. They also have an "appeasement call" to stop aggression. This is a soft sound used between mated pairs. If they are in great distress, they make a shrill "chree" call.

The history of the house sparrow is tied to modern science.

Carl Linnaeus described the bird in 1758. He gave it the scientific name Fringilla domestica. Later, the French zoologist Mathurin Jacques Brisson created the genus Passer in 1760. The name "domesticus" means "belonging to the house." This reflects how closely the bird lives with humans. There are 12 recognized subspecies divided into two main groups. These are the Oriental group and the Palaearctic group. These groups differ in things like cheek color and bill size.

Despite their huge numbers, house sparrows face many challenges. They are often viewed as agricultural pests. Because of this, people sometimes try to control their populations. Their numbers have actually declined in some specific areas. However, the IUCN Red List still classifies them as "least concern." This means they are not currently at high risk of extinction. They remain a culturally prominent bird in many societies. They have served as symbols of everything from commonness to sexual potency. Their ability to adapt to human change is truly remarkable.
