Range and Habitat

Java Sparrow: Originally native to Java and Bali in Indonesia, and possibly Madura, this sparrow has been introduced and is established in many parts of the world, from Asia to Australia, Africa and North America. Inhabits open woodlands, often bordering cultivated areas, and is also found in mangroves, grassland, towns and villages, and in both coastal and inland areas.

Breeding and Nesting

Java Sparrow: Breeding season extends from February to August with a peak in April and May. The nest is a loosely built structure of dried grass, constructed under the roofs and eaves of buildings or in bushes and tree cavities. Usually clutches of three to eight white eggs are laid. Both sexes incubate the eggs for 13 to 15 days. The chicks fledge between 21 to 30 days after hatching.

Foraging and Feeding

Java Sparrow: These sparrows primarily eat weeds, common lantana, passion flower, grass, bamboo, seeds, rice, insects, fruit and cultivated grains. They are easily attracted to backyard feeders. They forage on the ground or in growing vegetation. They climb on plant stalks with great agility. These sparrows are often seen in large flocks in rice fields.

Vocalization

Java Sparrow: Song is a soft liquid warble "t'lik" or "ch'lik" often repeated and call is a metallic "pik-pik-pik" They also have a very aggressive growl when threatened "GRRRRRRRR!"
