A Local and Global Problem

Globally, Indian Mynas are a widely recognised as a serious threat to biodiversity. In 2000, the species was listed among 100 of the Worlds Most Alien Invasive Species by the World Conservation Union, alongside species such as the Fox, the Cane Toad and the Feral Pig.

The awareness of the Australian community is also rising about the impacts that the Indian Myna is having on our native fauna. During 2004, the Indian Myna was voted the Pest of Australia in the ABC WildWatch Australia survey.

Impacts on Biodiversity

The Indian Myna is a highly intelligent and aggressive bird that successfully competes with our native species for food and nesting sites. As Indian Mynas nest in hollows, the negative impacts from this species are particularly high on hollow-dependant mammals and birds.

Other Impacts

Other negative impacts of Indian Mynas include:

  • Major damage to soft fruit crops such as Bananas and Papaya;
  • Accumulated droppings, particularly under communal roost sites. These droppings are problematic for a number of reasons, not least because they pose a threat to human health and they are a source of nutrient enrichment to waterways;
  • Building large untidy nests, using sticks, straw, feathers and rubbish, like scraps of paper and plastic, in roof spaces and cavities, which are a fire risk and an entry point for bird mites into houses. Bird mites bite, and they can cause asthma and hay fever if inhaled;
  • Noise at night from communal roosts near residential areas;
  • The potential to spread weed species. As Indian Mynas consume the fruits of exotic plant species they can assist in the spread of exotic weed species, such as Lantana; and
  • Consuming feed intended for domestic pets and livestock.
