Since I first wrote here about the thousands of dead blackbirds, followed by the estimated 100,000 dead drum fish, both in Arkansas, there have been several other mass animal deaths around the world.
Wildlife Deaths Around The World
Here are just a few of them:
* Two million small fish dead in Chesapeake Bay, Maryland, USA
* Hundreds of snapper fish found dead in New Zealand
* 50 to 100 jackdaws fell dead on a street in Falkoping, Sweden
* 450 red-winged blackbirds, brown-headed cowbirds, grackles and starlings found on a highway in Baton Rouge, Louisiana, USA
* 1,000 dead turtle doves rained down in Faenza, Italy
In the latter case, according to The Daily Mail:
Official results on the Italian birds are due tomorrow, but Rodolfo Ridolfi, a director at the regional zoological institute, said:’We are fairly confident the birds died as a result of massive indigestion brought on by over-eating.
The most likely cause are discarded sunflower seeds that were found on an industrial estate close to where the bodies of the turtle doves were found.
‘In essence the birds were greedy, ate too many of the seeds – which we have found inside them during autopsies – and this brought on the indigestion that led to their death.’
Why Did They Die?
Interesting – overeating and indigestion as cause of death?
Other experts have given New Year’s fireworks, thunderstorms, disease, cold weather and poisoning as possible reasons for the deaths.
Is Wildlife Mortality Normal?
The Economist last week provided an interesting link to a USGS survey of wildlife mortality for 2010, showing that incidents of wildlife deaths are actually quite common.
And check out this video from Chesapeake Bay; clearly this official isn’t too worried about the mass deaths there. But what do you think? What’s going on?
