House crow

The house crow is a black and grey bird.

It is slim and has a dark head. It also has a grey neck.

These birds live near people. They like to stay in big cities. They can find food in many places.

They eat many things. They eat fruit and grain. They also eat small animals. They can even eat scraps from trash.

They build nests in tall trees. They lay three to five eggs.

These nests are made of sticks.

This bird is very smart. It can even use tools to help it. It is a very busy bird.

The house crow is a slim bird.

It has a black head and throat. Its neck and breast are a light grey-brown. The wings and tail are black. These birds come from Asia. But they now live in many parts of the world. They often travel on big ships.

House crows are very smart. They are one of the few crows that use tools. They can even recognize themselves in a mirror. This is called self-recognition. This means they know they are looking at themselves.

These birds love to live near people. They stay in villages and big cities. They are omnivores, which means they eat almost anything. They eat fruit, grain, and insects. They also eat small animals like baby squirrels. Many crows find food in trash or near markets.

They build nests out of sticks. They like to nest in tall trees with big tops. Sometimes they even nest on telephone towers. A mother crow lays three to five eggs in a nest. They often sleep in large groups near bright streets.

The house crow is a slim bird from the crow family.

It is smaller in length than a carrion crow. It is also slimmer than a jackdaw. This bird has a shiny black forehead and throat. Its neck and breast are a light grey-brown color. The wings, tail, and legs are all black. These birds are very important to study because they live near people. They can survive in many different places around the world.

These birds are smart and can find food in many ways. They are omnivores, which means they eat many different things. They eat fruit, grain, and insects. They also eat small mammals and reptiles. Sometimes they even snatch baby squirrels from the air. Most of their food comes from the ground. They can also be found near garbage dumps or markets.

They are very good at using resources to stay alive.

Scientists first described this bird in the year 1817. A French expert named Louis Vieillot named it *Corvus splendens*. The name comes from a Latin word that means "brilliant."

There are different types of house crows in different places. One type has a grey neck collar in places like India. Another type is found in Myanmar and is very dark. Some types live in the Maldives or Sri Lanka. These birds have many regional variations in their colors.

House crows started in southern Asia. They are native to places like India, Pakistan, and Nepal.

They traveled to other lands on big ships. They arrived in East Africa around the year 1897. They have also been seen in Europe and Florida. In the Netherlands, they have been breeding since 1998. In Hong Kong, there are hundreds of these birds. They follow human populations as people move to new areas.

These crows are very clever animals. They are one of the few crows that use tools. They can also pass a mirror test. This shows they have self-recognition, which means they know they are looking at themselves. They build stick nests in tall trees or on telephone towers. A mother crow usually lays three to five eggs. They often sleep in large groups near bright streets. Their voice is a loud, harsh "kaaw-kaaw" sound.

The house crow, known scientifically as *Corvus splendens*, is a highly adaptable member of the crow family.

This bird is recognized for its ability to thrive in environments shaped by human activity. It is often referred to by several names, including the Indian, greynecked, Ceylon, or Colombo crow. While it originated in Asia, it has become a widespread species found on many different continents. This global presence is largely due to its ability to travel via shipping. Because it lives so close to people, understanding its behavior and movement is very important for scientists.

Physically, the house crow is a distinct bird with specific coloring patterns. Its length is intermediate, falling between the size of a jackdaw and a carrion crow. However, it possesses a slimmer body than either of those species. The bird features a richly glossed black forehead, crown, throat, and upper breast. In contrast, the neck and breast area are a lighter grey-brown color. The wings, tail, and legs remain solid black. There are also regional variations in the depth of plumage color and the thickness of the bill.

Taxonomists categorize several subspecies based on their specific locations and appearances. The nominate race, *C. s. splendens*, lives in Pakistan, India, Nepal, and Bangladesh, and it features a grey neck collar. In the dry regions of Iran and South Asia, the subspecies *C. s. zugmayeri* is found with a very pale neck collar. The *C. s. protegatus* subspecies lives in Sri Lanka, the Maldives, and southern India, and it appears darker grey. Finally, the *C. s. insolens* subspecies found in Myanmar is the darkest form and lacks a grey collar entirely.

The history of the house crow's scientific naming began in 1817. A French ornithologist named Louis Vieillot formally described the species as *Corvus splendens*. He based his description on a specimen that had been collected in Bengal. The specific epithet, *splendens*, is derived from the Latin word meaning "brilliant" or "glittering."

Since that initial description, the bird's range has expanded significantly due to human movement and trade.

House crows are highly successful because they are omnivorous scavengers. This means they can eat a wide variety of foods to survive. Their diet includes grain, fruit, insects, and other small invertebrates. They also hunt small mammals and reptiles, and they have even been seen snatching baby squirrels from the air.

Much of their food is found on the ground near human settlements, such as marketplaces or garbage dumps. They are so flexible that they can survive on nearly anything that is edible. This ability has allowed their populations to multiply alongside the explosion of human populations.

The distribution of the house crow shows how it moves across the globe. It is native to southern Asia, including countries like Nepal, India, and Thailand. Around 1897, it was introduced to East Africa near Zanzibar and Port Sudan. While they arrived in Australia via ships, those populations were eventually exterminated. In Europe, they have been breeding in the Dutch harbor town of Hook of Holland since 1998. A small population is also established near St. Petersburg, Florida, in the New World.

In Singapore, researchers recorded a high density of 190 birds per square kilometer in 2001.

Beyond their diet, house crows demonstrate remarkable intelligence and social behaviors. They are one of the very few species in the corvid family with documented tool usage. They are also the only known corvid capable of passing the mirror-mark test. This test identifies self-recognition, which is the ability of an animal to recognize itself in a mirror.

For nesting, they typically build stick nests in large trees with big crowns, though they sometimes use telephone towers. They often roost in large communal groups in well-lit, busy areas near human activity. Their presence can also have biological impacts, as they may carry diseases like Newcastle disease or the fungus *Cryptococcus neoformans*.
