Based on my own experience & observations and those of others. The native Noisy Miner (spelt it wrong before) I have here I have seen them attack baby Magpies, Blue faced Honey Eaters and others including Wattle birds.

The reason the Indians prosper in the town is the lack of incentive to actually trap & kill them, whereas I being rural have a sure fire way of thinning them out. Attempting to take over nesting hollows that I know about is fatal.

Silliest lot noted set up house in the same hollow tree as the male goanna. That did not end well, the dinosaur won.

They defend their territory and nests fiercely. So do Magpies.

They prosper in the suburbs and cities because food is there for the taking in the form of easy to access rubbish. Their main competition in that game are bin chickens (aka White Ibis).

The native one (light-grey bird) is Noisy Miner.

The imported pest (chocolate-brown) is Indian Myna.

They both chase off smaller birds, while additionally the Myna attempts to drive off everything else, by aggression and invading nests.

OK

They're like squadrons of fighter planes, snapping their little beaks loudly. Never seen them engage a bigger bird, just blitz and harass the hell out of it until it flies away.

I had to reshape my garden getting, rid of a Grevillea Robyn Gordon and a Banksia because of Noisy Mynas monstering smaller birds like pardalotes and Eastern Spine Bill, which I would find dead in the garden. Used to have a tribe of Indian Mynas in the area, nesting in the corner of my neighbour's roof. I even went to the trouble of building a trap to a design from the net. I didn't catch any, but eventually they disappeared after the roof was repaired; don't know why as I see them elsewhere in my suburb and they would find another nesting site. Maybe the Kookaburras gave them a hard time nesting. But then the wrens appeared.

The local mens' shed used to make traps to order for a small fee. The local council requires you to take a course in euthenasing them (basicly wring their necks) - gassing considered unacceptable.

Leaving food in a trap is a way to get them. The Noisy Miner squadron will actually chase other birds off.

A bin Chicken will not fit in a Minah trap and the twitters are too small in most cases to get caught in one, if the mesh is right.

It is obvious that the council cant think past WWII. Zyklon B was a crime against humanity and ghastly stuff. Carbon Monoxide is much gentler than the violence of neck wringing, which can be stuffed up.

Back when I could catch Mynas I would simply pop them in the toilet bowl and leave the lid down. Come back in half an hour and they are dead. No violence there.

But then they wised up and I can no longer get my hands on them. They are highly intelligent and can pass knowledge on to their offspring.

I suspect that the council does not much care how you despatch them as long as you don't frighten the kiddies, but must be seen to be doing the "right thing".

No rug rats here so its open season. Foxes, Rabbits & feral cats that also decimate the wildlife are very good peppered if they're close.

The cats & foxes delight in sitting above the nests of the Rainbow Birds (Ground nesters) waiting to grab them whilst a tree guard is good, for the benefit in lambing season a bullet is better.

Foxes are out of control & the government has made more habitat for them here. I believe the collective effort last lambing season was over forty foxes. We have no Curlews left. The Hares have taken up putting the babies in the house garden. At one point the nearest neighbours cats had decimated a colony of antechinus marsupial's, along one of my boundary fences.

This country seems to be the world leader in promoting feral species like Deer, Foxes & Pigs whilst the native species are being decimated.

Governments do care about how they are dispatched. It is legal to gas Indian mynas with carbon monoxide or carbon dioxide. The latter is safer to handle because a lethal dose will cause one to gag, whereas a lethal dose of the former will not, as not a lot is needed. Councils have designs for traps on their sites and once it is full of Mynas, just surround it in a large bin liner and then fill the liner with CO2. The birds will be dead in ten seconds.
