Common Indian Mynas can be an economic problem because they damage fruit and grain crops and their noise and smell can be annoying where they are in large numbers. Mynas can also spread mites and they have the potential to spread disease to people and domestic animals. Mynas become quite fearless of people if they are not hassled and can be a problem in outdoor eating areas by stealing food off people’s plates. There are a few records of mynas attacking people, but this is not common.
Perhaps the Common Indian Myna’s most serious “crime” is that it competes aggressively with native wildlife for nesting hollows. Common Indian Mynas nest in tree hollows, or places like them, such as holes in roofs. Hollows are in short supply over much of Australia because of clearing for agriculture.
