My son came home today and explained that a bird had fallen out of the sky and landed in the school courtyard dead from the impact.
He said the science master explained that this was happening world wide at the moment.- could the two be related ????

Birds fall from sky over town

THOUSANDS of birds have fallen from the skies over Esperance and no one knows why.

Is it an illness, toxins or a natural phenomenon? A string of autopsies in Perth have shed no light on the mystery.

All the residents of flood-devastated Esperance know is that their "dawn chorus" of singing birds is missing.

The main casualties are wattle birds, yellow-throated miners, new holland honeyeaters and singing honeyeaters, although some dead crows, hawks and pigeons have also been found.

Wildlife officers are baffled by the "catastrophic" event, which the Department of Environment and Conservation said began well before last week's freak storm.

On Monday, Esperance, 725km southeast of Perth, was declared a natural disaster zone.

District nature conservation co-ordinator Mike Fitzgerald said the first reports of birds dropping dead in people's yards came in three weeks ago. More than 500 deaths had since been notified. But the calls stopped suddenly last week, reportedly because no birds were left.

"It's very substantial. We estimate several thousand birds are dead, although we don't have a clear number because of the large areas of bushland," Mr Fitzgerald said.

Birds Australia, the nation's main bird conservation group, said it had not heard of a similar occurrence. "Not on that scale, and all at the same time, and also the fact that it's several different species," chief executive Graeme Hamilton said. "You'd have to call that a most unusual event and one that we'd all have to be concerned about."

He expected birds would return to the area once the problem - natural or man-made phenomenon - was fixed but said it was vital the cause was identified.

The Department of Agriculture and Food, which conducted the autopsies, has almost ruled out an infectious process.

Acting chief veterinary officer Fiona Sunderman said toxins were the most likely cause but the deaths could be due to anything from toxic algae to chemicals and pesticides.

Dr Sunderman said there were no leads yet on which of potentially hundreds of toxins might be responsible. Some birds were seen convulsing as they died.

Michelle Crisp was one of the first to contact the DEC after finding dozens of dead birds on her property one morning.

She told The Australian she normally had hundreds of birds in her yard, but that she and a neighbour counted 80 dead birds in one day.

"It went to the point where we had nothing, not a bird," she said.

"It was like a moonscape, just horrible. But the frightening thing for us, we didn't find any more birds after that. We literally didn't have any birds left to die."


Dead birds rain down on towns half a world apart

It could be the plot of a horror film, but in two towns on opposite sides of the world the mysterious phenomenon of thousands of dead birds dropping out of the sky is all too real.

Officials are baffled by the unexplained deaths which have affected Australia and the U.S.

Three weeks ago thousands of crows, pigeons, wattles and honeyeaters fell out of the sky in Esperance, Western Australia.

Then last week dozens of grackles, sparrows and pigeons dropped dead on two streets in Austin, Texas.

As birds continue to die in Esperance and the town's dawn chorus remains eerily silent, vets in both countries have been unable to establish a cause of death - despite carrying out a large number of autopsies on the birds.

Wildlife officials from Western Australia's Department of Environment and Conservation said they were baffled by the "catastrophic event" but emphasised the deaths had nothing to do with a severe storm which recently struck the area, as the birds had started dying before then. District nature conservation coordinator Mike Fitzgerald said: "It's very substantial.

"We estimate several thousand birds are dead, although we don't have a clear number because of the large areas of bushland."

Birds Australia, the country's largest bird conservation group, said it had not heard of a similar occurrence.

"You'd have to call it a most unusual event and one that we'd all have to be concerned about," said chief executive Graeme Hamilton.

Dr Fiona Sunderman, chief veterinary officer of the Department of Agriculture and Food, suspects the cause of death is some form of toxic poisoning.

Esperance resident Michelle Crisp, who normally sees hundreds of birds roosting in her garden, counted 80 dead ones in one day.

"It went to the point where we had nothing, not a single bird," she said. "It was like a moonscape - just horrible."

In Texas, officials are also working on the toxic poisoning theory. Adolfo Valadez, medical director for Austin and Travis County Health and Human Services, said it might be weeks before any conclusive results were known.

Such was the concern that the birds suffered deliberate toxic poisoning that several streets were closed in Austin while police and fire crews checked the area for any substance that might be of harm to humans.

"This was a precautionary measure. We certainly take these kinds of thing seriously, especially following 9/11," said Mr Valadez. "It may be a matter of time before we know what happened and why it happened. There is no threat to public health."

Federal officials in Washington said they were monitoring the situation, but a spokesman for the Department of Homeland Security said: "There is no credible intelligence to suggest an imminent threat to the homeland or Austin at this time."
