Noisy Miner, Adelaide Botanic Gardens

I was a little amused last week when there was quite a flurry of correspondence in the Letters to the Editor section of our state-wide newspaper, The Advertiser. A reader wrote in complaining that something should be done about Myna birds in his suburb which he considered  pests. He claimed that they were chasing away all the other birds, especially the smaller ones such at wrens and thornbills.

The next day the paper printed a whole page of rebuttals – or rather, a raft of claims of mistaken identity. Several years ago I, too, experienced getting into a long discussion with someone who was adamant that there were Mynas around the Salisbury area in the north of the city. They just would not be convinced otherwise.

The fact remains that there are currently no Common Mynas (also known as Indian Mynas) in South Australia. This introduced species is, however, relatively common in the eastern states and their range is increasing. Only last week my 7yo grandson reported that they now have them in their garden in Artarmon for the first time. (I have seen them up the street but never in their garden.) I have included a photo of a Common Myna below, taken several years ago in the Taronga Park Zoo in Sydney, a few suburbs away from my son’s home.

The species that the correspondent was concerned about was the Noisy Miner, an Australian native honeyeater species as shown in the photo above, taken a few years ago in the Adelaide Botanic Gardens. The Noisy Miner is a gregarious and mostly aggressive species which can be very dominant in some situations. Their bossy ways discourage smaller species like wrens, thornbills and other honeyeaters until those species leave and never return. One of the ways of combating their habits is to plant up gardens with smaller Australian native plants because they prefer more open, grassy, lawned areas.

As an interesting aside, we do not have Noisy Miners on our five acre block on the edge of Murray Bridge. They are relatively common along the river reserves and throughout the town, but in over 30 years they have never – to my knowledge – visited out property, though I have expected them for some years now. I did see one small family group about 500 metres down the side road from our place, but so far they have not moved any closer. We certainly do not want them invading our orchard – the Mallee Ringneck parrots are pest enough in the fruit trees. (Placing bird netting over the trees mostly works effectively.)

The threat of Common Mynas

The following is a quote from our government department PIRSA (Primary Industry):

The species is listed by the IUCN (World Conservation Union) as one of 100 of the world’s worst invasive alien species alongside Common Starlings, Red Foxes and Cane Toads. The Common Myna is a moderate pest of agriculture causing damage to orchard fruits such as fig, apple, pear, strawberry, guava, mango and grape. It also damages standing cereal crops including maize, wheat and rice.
In several countries it is considered an environmental pest and is reported to eat eggs and young birds and mammals including endangered species. The Common Myna aggressively competes for nest hollows and food, adversely affecting the breeding success of other birds and hollow-nesting mammals. It has been observed
attacking terns on islands as well as taking the eggs of other sea birds, possibly interfering with those birds’ breeding and general behaviour. The Common Myna is also known to spread avian malaria to other birds.

It also has other documents relating to potential animal pests such as the Cane Toad.
