Namesake white wing bars make this prinia relatively distinctive. Also note white throat, pale yellow belly, and black-and-white tips to tail feathers. Endemic to Java, Sumatra, and some smaller adjacent islands. Inhabits scrubby habitats, such as farm field edges and old plantations, as well as mangroves. Often seen in low vegetation, but forages at all levels of habitat. Sometimes forms small flocks outside the breeding season. Song is a twanging, repetitive “chwet-chwet-chwet” or “cheweet-cheweet-cheweet”. Calls include a sharp “chwit” and a harsh, nasal “jee!”
