  • It is also present in many islands in the Atlantic Ocean, Indian Ocean, and Pacific Ocean.
  • France has had reports of breeding mynas.

Potential or Known Impacts:
  • Negative impacts are seen as this species is known to become dominant over native species over food and nest sites, predation on native species, and spreading invasive plants.

How could it get here?
  • On large landmasses, including within large islands, invasion pathways appear to be primarily along roads.
  • Pet shops and subsequent escapees from private collections are a key pathway.
  • On oceanic islands, invasion pathways appear to be primarily via ships, particularly large ferries.

Is it found in Northern Ireland?
  • Not present in Northern Ireland.

Methods for Prevention:
  • Most introductions have involved transport and release; prevention of transporting this species is key. The removal of this species should be imperative, where it has been demonstrated that this species has negative impacts on native plants and species.
  • Report all sightings.
