up at the burrum heads speed comp we saw a helicopter hit a flock of birds.
the pilots were flying low looking for some boaties that had come to a sad end.
one hell of a bang!!
Haha, was just about to relate this-
TV crew filming vando
helicopter flys past... CRACK!
helicopter didn't seem to go quite right after that, though nor did the bird

I see alot more foxes, rabbits (yes they are in qld) and hares at work now. I don't mind foxes and I haven't broken an ankle on a rabbit hole yet and for every one of either I see many more feral cats or canetoads or feral dogs yet they don't really bother me either- at this stage council/govt has effective controls in place. Joe public having gun availability in the name of pest control does bother me though.
As for "plagues" it is just the way the world works. An introduced species will always peak before a happy medium is reached, the fact that they are new makes it stand out also. As a kid even it seemed that everything was a pest be it native or introduced and was to be shot or trapped or poisoned- starlings, sparrows, cane toads, flying foxes, cockatoos, crows etc. In brisbane now sparrows and starlings are a rare sight. The gecko was the recent addition that everyone saw but even they have decreased in numbers a bit, Mynah birds are another. It is almost always human doing that causes the imbalance, eventually nature deals with it for example crows learning to eat cane toads. But in the meantime measures put in place such as better building regulations or don't feed the ibis are far more effective than people shooting away at them.
