Java Sparrow

One of the most popular cage birds in East Asia, Java sparrows are striking finches with grey plumage, a bold black head, distinctive white cheek patches, and a bright red bill. Native to Java and Bali in Indonesia, they have been introduced to many parts of Asia, Africa, and the Americas. They inhabit open grasslands, rice fields, and farmland, often becoming pests on rice crops. Listed as Vulnerable in their native range due to severe trapping pressure for the cage bird trade.
