Taxonomía

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.

Comportamiento

The Javan myna is omnivorous and eats seeds, fruit, nectar, insects and human waste. It is often found in large groups. Its voice is similar to that of the common myna. It builds its nest in holes. The eggs are bluish-glaucous. Javan mynas are bold and not very afraid of humans. Javan mynas are kept in cages in Malaysia and Indonesia. 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.[citation needed] If one of them is separated, they would tend to tweet to attract other mynas of their kind to come over.
