Blackbirds dead in Arkansas

Shortly after midnight on New Year's Eve, 3,000 blackbirds fell from the sky in a 1.5 square mile section of Arkansas. Collected carcasses were sent back for testing but the scientists were unable to find out whether the birds died before or after hitting the ground, and found no trace of disease or toxin. Scientist believe the birds were either disoriented by a thunderstorm, or that fireworks had startled them, confusing them and leaving them headed toward the ground.
