Previously endemic to the Indonesian islands of Java and Bali, the Javan Myna (Acridotheres javanicus) was reportedly introduced to Singapore in the 1920s through the caged bird trade.
Since becoming established in Singapore, this invasive species has flourished and is now the most commonly found bird in the country.
The Javan Myna slightly resembles the Common Myna (Acridotheres tristis), once a commonly found bird in Singapore and a native species that has declined due to competition with the introduced Javan Myna.
The Common Myna can be distinguished from the Javan Myna by the yellow skin around its eyes and brown body.
