Indian Myna - Acridotheres tristis - numbers have exploded across Canberra since they were deliberately introduced, and are a serious environmental threat to native wildlife. Indian Mynas:

• are one of the most invasive animal species in the world
• take over nesting hollows, evicting birds and small mammals, and prey on nestlings
• pose some small human health risk, and
• the nesting material they bring into roof cavities and other spaces in buildings can be a fire hazard.

We have the same problem in South Africa, Durban to Guateng.
