Java sparrows are very social. They like to live in groups. They eat seeds and grain. They often live in rice fields.
These birds use sounds to talk. They make fast trill-calls when they are angry. They make slow, soft calls to be friendly.
Many people keep them as pets. People in Asia have done this for a long time. In the wild, these birds are in danger. There are fewer than 10,000 left. They are losing their homes.
Some birds are even bred to be white.
The Java sparrow is a small, colorful bird.
It belongs to the estrildid family of birds. These birds live on islands like Java, Bali, and Bawean in Indonesia. They are very social and like to live in groups. Most of these birds eat grain and seeds. They often live in open grasslands or near farms. Because they eat rice, they were once seen as pests in rice fields.
Adult birds have a very distinct look. They have grey feathers on their backs and chests. Their bellies and feet are a bright pink color. They also have a thick red bill and a red ring around their eyes.
Young birds look different from adults. They have brown feathers and plain heads. Very young birds even have black beaks with pink at the base. These birds use sounds to talk to each other. They make fast, loud trills when they are being aggressive. They make slow, soft trills when they are being friendly.
People have studied these birds for a long time. The Swedish naturalist Carl Linnaeus first described them in 1758. He gave them the name *Loxia oryzivora*. This name comes from Latin words for "rice" and "eating." He used a description from George Edwards. Edwards was an English naturalist who wrote about them in 1743.
Scientists have changed the bird's group name several times. They used the name *Padda* for a long time. In 2009, they moved them to the *Lonchura* group. Then, in 2020, they moved them back to *Padda* after more studies.
Java sparrows are popular pets in many places. People in China kept them during the Ming Dynasty. In Japan, people have kept them since the 1700s. They even appear in old Japanese paintings.
In the United States, they were very popular in the 1960s and 1970s. Today, they live in places like Hawaii and Puerto Rico. People have bred them to have many colors. You can find white, silver, cream, and even a called sakura buncho. Some birds are also called pied Java sparrows.
Even though they are popular pets, wild birds face hard jobs. They are losing their natural homes. People also hunt and trap them. Because of this, there are fewer than 10,000 birds left in the wild.
The IUCN Red List says they are endangered. They are also part of a group called CITES. This group helps protect animals from being traded illegally. This is important because people want them for their beautiful songs.
The Java sparrow is a small passerine bird known for its striking appearance.
It belongs to the family Estrildidae. This species is a resident breeding bird in several Indonesian locations, including Java, Bali, and Bawean. Because these birds feed mainly on grain and other seeds, they have often been viewed as agricultural pests. This is especially true in rice fields, which influenced their scientific name. Today, the bird is a popular subject in aviculture, or the practice of keeping birds in captivity.
An adult Java sparrow has a very specific look that makes it easy to identify. They possess grey upperparts and a grey breast, which contrasts with a bright pink belly. Their heads are black with white cheeks, and they feature a distinctive red eye-ring. Their thick bills and feet are also red.
Both males and females look similar in adulthood. Immature birds look quite different, with brown upperparts and pale brown underparts. Very young birds even have a black beak with a pink base.
These birds use complex sounds to communicate with one another. A study by Furutani et al. in 2018 showed that they produce different trill-calls based on their social situation. This is a form of social communication that helps them convey specific intentions. For example, when birds are in aggressive interactions, they emit faster trill-calls. These aggressive calls also have higher sound pressure levels and higher entropy. In contrast, during affiliative behaviour, which refers to friendly social interactions, the trill-calls are slower and softer.
Scientific classification for the Java sparrow has changed as researchers learned more about its genetics. The Swedish naturalist Carl Linnaeus formally described the species in 1758. He published his description in the tenth edition of his work, *Systema Naturae*. He used the binomial name *Loxia oryzivora*. The name combines the Latin word *oryza*, meaning "rice," with *-vorus*, meaning "eating." Linnaeus based his work on descriptions by George Edwards from 1743. For a long time, the species was classified in the genus *Padda*. In 2009, preliminary genetic studies moved them to the genus *Lonchura*. However, more detailed genetic analysis in 2020 returned them to their older status in *Padda*.
Humans have kept Java sparrows as cage birds for many centuries. In China, they were popular during the Ming Dynasty. In Japan, they have been kept since the 17th century and appear in many traditional paintings.
In the United States, they were very popular during the late 1960s and early 1970s. However, their import was eventually banned. In California, it remains illegal to possess them due to a perceived threat to agriculture. In Asia, breeders often raise them from birth, which helps the birds become very tame and attached to humans.
In captivity, humans have bred the birds to show a wide variety of colors. These include white, silver or opal, fawn or isabel, pastel, cream, and agate. The agate color is currently rare in European captive specimens. In Japan, a pied version of the bird is known as the sakura buncho.
The species has also been introduced to many other places. They have breeding populations on several Hawaiian Islands, particularly Oahu. They are also common near San Juan in Puerto Rico. Other sightings have occurred on Christmas Island and in Jamaica.
Despite their popularity, the Java sparrow faces serious threats in the wild. They are currently evaluated as endangered on the IUCN Red List of Threatened Species. This means there are likely fewer than 10,000 individuals remaining in the wild. The birds face a loss of natural habitat, hunting, and trapping by people who view them as pests. They are also threatened by the illegal exotic pet trade because people want their distinctive songs. To help protect them, the species is listed on Appendix II of CITES, an international agreement to protect wildlife.
