Java Sparrow

Description

Habitat

• Distribution: The Java Sparrow is native to Indonesia, particularly the islands of Java, Bali, and Bawean. The Fawn Java Sparrow, as a domesticated color variant, is primarily found in captivity worldwide.
• Environment: In the wild, Java Sparrows prefer open grasslands, cultivated fields, and areas near human habitation. In captivity, they are often kept in aviaries and cages.

Diet

• Primary Food: Seeds, particularly those from grasses and cultivated crops like rice, are the main component of their diet.
• Supplementary Food: Fruits, vegetables, and occasional insects are also part of their diet, especially in captivity where variety is provided.
• Feeding Behavior: They forage on the ground, searching for seeds, and in captivity, they will eat from feeders or directly from the substrate.

Breeding

• Breeding Season: In the wild, breeding typically occurs during the rainy season, but in captivity, they can breed year-round if conditions are right.
• Nest Location: Nests are built in trees, shrubs, or nest boxes provided in captivity. The nest is constructed from grasses, feathers, and other soft materials, forming a dome-shaped structure.
• Egg Quantity: Clutches usually consist of 4-6 eggs.
• Incubation Period: About 13-15 days.
• Fledging: Chicks fledge around 21-28 days after hatching.

Lifespan

• In the Wild: Typically around 5-7 years.
• In Captivity: Can live up to 8-10 years or more with proper care.

Behavior

• Social Structure: Fawn Java Sparrows are social birds, often seen in pairs or small flocks. In captivity, they thrive in the company of their own kind or other finches.
• Vocalization: Their calls are soft, melodious chirps and whistles, often heard in communication and courtship.
