Common myna (Acridotheres tristis)
An aggressive introduced bird of towns and farms that takes over tree hollows and nest boxes from native birds and small mammals.
Key facts
Type: Pest animal, bird.
Native to: South and central Asia.
Established in: QLD, NSW, ACT, VIC.
Other names: Indian myna.
Identification
- Brown bird with a black head, yellow bill, yellow eye patch and yellow legs.
- White wing patches show in flight.

Where it lives
Urban and peri-urban areas, farms and roadsides.
Why it matters
- Evicts native birds and mammals from hollows.
- Nuisance at food outlets and buildings.
How it spreads
- Spreads along roads and human settlement.
Control methods
- Trapping with purpose-built myna traps and humane euthanasia.
- Removing food sources and blocking nesting sites in buildings.
Site hygiene and welfare
- Keep food waste covered at camps and depots.
- Use methods set out in the national model codes of practice and standard operating procedures for the species.
- Coordinate control with neighbours and the local government biosecurity plan, as isolated effort is quickly undone by reinvasion.

Every state and territory places a duty on landholders and people working on land to prevent the spread of invasive species, such as the general biosecurity obligation in Queensland and the general biosecurity duty in New South Wales. Declarations and control requirements differ between states and local government areas, so check the current official list before work starts.
