Legolas said:I heard about the reason why some birds died in Romania a few minutes ago in the radio:
article said:DOZENS of birds found dead in eastern Romania drank themselves to death, the local sanitary and veterinary authority has revealed.
The starlings died after they ate grapes left over from the wine-making process, Romeu Lazar, head of the local DSVSA, told the Agerpres news agency.
The cause of death was determined after the contents of the birds' gizzards were analysed, he added.
On Saturday, several residents of Constanta, 260 kilometres east of Bucharest, alerted the authorities after they discovered dozens of dead starlings on the outskirts of the city.
They said they feared the birds had been killed by avian flu, but the DSVSA immediately ruled out that possibility.
The incident came after unexplained mass bird and fish deaths were reported in several countries, including the United States, Sweden and Britain.

As I heard it, it sounded just strange to me, that birds would eat something that contains alcohol. Maybe whitewashing, but I'm not sure.
My initial reaction to this explanation was that it was a load of old cobblers. Are there any grapes left over at this time of year (winter) in Europe? Does the total wine making process itself leave any sizeable piles of grapes around, that is, of a sufficient amount to get dozens of starlings drunk?
That aside though, starlings can get drunk from eating grapes (after the process of fermentation in their stomachs), in the appropriate season of course.

"Here is an interesting story. A few years ago, a farmer brought two drunken red-tailed hawks to a bird rescue centre. They were stupefied, comatose even, but alive. Following the detective work, here is what they figured had happened.
The farmer had spread grape pumice (mash made from wine grapes) on his fields as fertilizer. Normally, any falling moisture would have been enough to break down the grape pumice and wash it into the soil, but there was little moisture that particular winter. So the grapes didn’t decompose, but fermented instead. The hawks did not eat the grapes. Starlings did. The starlings got good and drunk and stupefied. Many died, but the ones that didn’t couldn’t fly very well. Since starlings, even when drunk, generally fly in a straight line, they became easy pickings for these two patrolling hawks, who made a Christmas feast of starling, marinated au Pinot Noir. And like little boys who eat too many brandied berries at Christmas, the hawks also got falling-down drunk. The hawks were put on wooden roosts in an incubator, and once they recovered from their binges, they flew off none the worse for wear."

Anyway the explanation that the birds drunk themselves to death now sounds a bit more reasonable and plausible. But because of the time of year and also the amount of grapes needed, these factors render this scenario (cover story?) less likely to me.
