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.
Taxonomy
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.[1]

Behaviour
Javan mynas are bold and not very afraid of humans.[2] Javan mynas are kept in cages in Malaysia and Indonesia.[2]
Javan mynas are found in pairs and associate in larger groups. Its voice is similar to that of the common myna. It builds its nest in holes.
The birds scavenge in groups, minimum two but usually three or more, with all except one feeding and one usually at a vantage point keeping a look out. If the bird that is keeping watch sees anything that might pose a threat, it alarms the group members with a high pitch tweet and they all flee the area swiftly.Script error: No such module "Unsubst".
