Grapes, bushfires and birds

We have just harvested our grapes. Though not as prolific and luscious as last year, there is still a sizeable crop and they taste beautifully sweet. We have adark red variety which is under bird netting to stop the birds from cleaning out the entire crop before they even change to their ripe colouration.
I was listening to the radio when there was a discussion with one of the Yarra Valley vintners. Their grapes had been affected by smoke from the bushfires raging throughout February. As a result once the first batch had been pressed, the taint from the smoke had made its way into the vintage. Thus the grape harvest had to be abandoned, the nets pulled off and the remaining grapes were available to the wildlife. I imagine the birds were able to have a feast.
I had been wondering how the bird population is surviving as food in the fire affected areas must be in short supply. Perhaps this grape harvest disaster (only for some of the Yarra Valley producers) will ensure that the lovely, raucous native birds of the Australian bush can survive for long enough before the bush regenerates and provides their normal food.
