It's been raining dead birds, washed up dead fish, and now it's 200 dead cows in a pasture in Stockton, Wisconsin.
The owner of the cattle said he suspects the cows died from a virus, like IBR (infectious bovine rhinotracheitis) or BVD (bovine virus diarrhea), which can cause respiratory and reproductive problems.
Samples of the dead animals are going to be tested, but without really knowing what caused the deaths, officials said other animals and people in the area will likely not be affected by whatever killed the cows.
The death of the cows is just the latest of more dead animals dying in the United States and throughout the world.
People started paying attention to the mass animal deaths New Year's Eve, when thousands of black birds fell from the sky in Arkansas
Many of our readers and elsewhere point the cause of death from everything, including mass poisoning, all the way to apocalypse.
Officials who seem to be all knowing say the bird deaths were probably a result of a change weather conditions.
"Not to worry," Harvard biologist E.O. Wilson, "These are not portents that the world is about to come to an end."
So, everything is under control according to E.O. Wilson.
