Java finch, Java rice sparrow, Java rice bird
The adult Java sparrow is unmistakable, with its grey upperparts and breast, pink belly, white-cheeked black head, red eye-ring, pink feet, and thick red bill. The male and the female are similar. Immature birds have brown upperparts and pale brown underparts, and a plain head. Very young birds have a black beak with a pink base.
These birds do not migrate and are found throughout the year in Java, Bali, and Bawean in Indonesia. They inhabit open woodlands, open grasslands, savannas, cultivated areas, villages, and towns.
Java sparrows are diurnal and very gregarious birds that live and forage in flocks. Outside of the breeding season flocks may travel short distances in search of better feeding areas. The call of Java sparrows is a ‘chip’, and their song is a rapid series of call notes ‘chipchipchipchipchipchip’.
Java sparrows are herbivores (granivores). They feed mainly on grain and various seeds.
Java sparrows are monogamous birds that form pairs. During the breeding season, males sing songs in order to attract females. Java sparrows construct their nests in a tree or building. Females lay up to 8 eggs and incubation takes approximately 14 days. The chicks are protected by both parents and start to breed when they are 1 year old.
The main threats to the Java sparrow include an ongoing loss of natural habitat, hunting in some areas, and trapping (as a pest) in others. These birds are also severely threatened by the illegal exotic pet trade as they are sought after for their distinctive song.
According to IUCN Red List, the total population size of the Java sparrow is 1,000-2,499 mature individuals. Currently, this species is classified as Endangered (EN) on the IUCN Red List, and its numbers today are decreasing.
