[4] 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.

[3] The Javan myna is omnivorous and eats seeds, fruit, nectar, insects and human waste.

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.

[6] Juvenile Javan mynas will no longer be fed in the nest and will learn to beg for food from its parents.

[7] When begging, juveniles stand at the same spot every now and then with its wings hanging down, fluttering lightly occasionally beside its body.

[8] The eggs of a Javan myna are blue in colour and takes 13-14 days to hatch.
