Invasive species

The IUCN declared the common myna as one of only three birds among the world's 100 worst invasive species (the other two being the red-vented bulbul and the common starling).The French introduced it in the 18th century from Pondicherry to Mauritius with the aim of controlling insects, even levying a fine on anyone persecuting the bird. It has since been introduced widely elsewhere, including adjacent areas in Southeast Asia, Madagascar, the Middle East, South Africa, the United States, Argentina, Germany, Spain and Portugal, the United Kingdom, Australia, New Zealand and various oceanic islands in the Indian and Pacific Oceans, including prominent populations in Fiji and Hawaii.

The common myna is regarded as a pest in South Africa, North America, the Middle East, Australia, New Zealand and many Pacific islands. It is particularly problematic in Australia. Several methods have been tried to control the bird's numbers and protect native species.
