Java Sparrow (Lonchura oryzivora) lives in grassland, rice fields across Southeast Asia. It feeds on rice and seeds. Its conservation status is Vulnerable.
Fascinating facts about the Java Sparrow
- Carl Linnaeus first gave the Java sparrow a scientific name in 1758, calling it Loxia oryzivora in the tenth edition of Systema Naturae. He based this on an earlier 1743 illustration by George Edwards, who called his specimen a "Padda or Rice-bird" and mistakenly thought it came from China.
- A single clutch can hold up to eight eggs, which the pair builds in a tree or building, reflecting the species' adaptability to both wild and human-made structures. Their gregarious nature drives them to feed in large flocks on open grasslands and cultivated fields, where they primarily eat grain and seeds. Such social foraging and flexible nesting help the sparrow exploit agricultural landscapes, but also bring it into conflict with farmers who once labeled it a rice pest.
- The IUCN now lists the Java sparrow as endangered, estimating fewer than 10,000 individuals remain in the wild, and it appears on CITES Appendix II. Habitat loss, hunting, and trapping for pest control have driven its numbers down, while the illegal exotic-pet trade adds further pressure. erasing a bird that has been part of Asian culture for centuries.
- At just 15 to 17 cm long, the Java sparrow rivals a house sparrow in size, yet its average weight of 24.5 g makes it one of the largest species in the estrildid family, edging out the black-bellied seedcracker.

About the Java Sparrow
In the lush, emerald landscapes of its native Indonesia, the Java Sparrow flits with irrepressible vitality, its chestnut-brown plumage glistening like polished terracotta as it darts between the slender stems of paddy fields. With a flick of its black throat patch, this diminutive bird takes to the skies, its wings beating in a furious blur as it pursues the ephemeral abundance of rice grains and insects. As it alights upon a swaying reed, the Java Sparrow's melodic trill echoes through the air, a poignant reminder of the delicate beauty that teeters on the brink of vulnerability.
