In 2000, the Common Myna (Acridotheres tristis) was declared amongst the top 100 of the world's most invasive species by the International Union for the Conservation of Nature (IUCN). Common Mynas have the potential to cause significant negative impacts on biodiversity.

Description

  • brown, with glossy black head, neck and upper breast
  • bright yellow bills, eye skin, legs and feet
  • 23-26 centimetres long, weighing between 82-143 grams with a wing span of 120-142 millimetres
  • has distinctive white patches on wings that are visible in flight.

Problems caused by the Common Myna

This bird, native to India, has been declared the second greatest threat to native birds after land clearing.

It is currently spreading through eastern Australia, yet in some areas its arrival is so recent that unknowing residents welcome it into their backyards and encourage it to feed alongside native birds.

Environmental damage

  • Mynas may compete aggressively for nesting hollows, displace, out compete and exclude many native wildlife species, especially hollow-dependant animals such as parrots and gliders
  • potential reservoir for diseases such as avian malaria
  • damages fruit, vegetables and cereal crops
  • spreads weeds such as lantana and fireweed
  • a social nuisance with large roosts and nests causing noise, mess, potential allergies and a fire hazard.

Social harm

  • pose a potential health risk to humans
  • may nest in the roofs of houses where accumulated droppings and mites provide ideal conditions for disease
  • inhaled mites can cause asthma and hay fever and their bites cause itching.

Economic damage

  • The management of over-abundant common myna populations can be very expensive and is rarely successful.

Control

What the City of Gold Coast is doing

In response to an increasing number of requests from Gold Coast residents and community groups, our Animal Management section conducted a trial Common Myna bird management program within the Currumbin area during 2011. The trial was based on successful community-led Common Myna bird management programs undertaken within the ACT and New South Wales. The aim of the trial was to provide information to the community about the species and offer the community resources to humanely capture and euthanase Common Myna birds.

Having reviewed the trial management program, the City resolved at its meeting on 24 October 2011 to continue to facilitate the provision of Common Myna bird traps as a service to ratepayers.

What you can do

Did you know that seed for native birds can attract Indian Mynas?

These birds may then dominate your garden and chase away other birds. If you see Mynas at your bird feeder or in your garden, stop putting out bird seed.

  • If possible, feed your pets indoors rather than leaving pet food outside.
  • If you have chickens or ducks, feed them in a secure pen so Mynas cannot access the food.
  • If you feed goats or horses, stay with the animals while they are feeding. Clean up spilled or leftover pellets or grain.
  • Common Myna birds nest in tree hollows, roofs, exotic trees and dead, hanging palm fronds. To break the nesting cycle, block holes in roofs and eaves and keep palms trimmed. If using artificial nest boxes to encourage wildlife, use a nest box with a backward facing entry. This allows access to small possums, gliders, small bats and some native birds while preventing common Mynas from entering.
  • Consider borrowing a Common Myna bird trap from the City to capture Common Myna birds (for further information please call us on 1300 GOLD COAST or 07 5582 8211.
  • Report sightings of Mynas - especially roost sights and large populations - to Myna Scan via their website. This will assist in research and monitoring.
