The Javan myna (Acridotheres javanicus), also known as the white-vented myna, is a species of myna. It is a member of the starling family. It is native to Bali and Java. It has been introduced to other Asian countries, and as far away as Puerto Rico.
The Javan myna is sometimes included in the great myna (Acridotheres grandis) or the jungle myna (A. fuscus). The International Ornithologists' Union recommends not using the name "white-vented myna" to avoid confusion with the pale-bellied myna A. cinereus.
The Javan myna is mainly black. The wings are brownish-black, and the primary feathers have white bases, displayed in flight as a striking white wing bar, along with a white tail bar. The undertail-coverts are white. There is a short crest on the forehead. Its beak, legs and feet are yellow. The eyes are lemon-yellow. The immature is browner. Its length is 21–23 cm (8.3–9.1 in). Its weight is about 100 g (3.5 oz).
The Javan myna is native to Bali and Java, and has been introduced to southeastern Thailand, southern Malaysia, Singapore, Sumatra, the Lesser Sundas, Taiwan, Puerto Rico, Japan and Nepal. It is found in cities and cultivated... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Javan Myna is recorded against all the birds logged in Gunung Leuser National Park (6 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
