Mass Bird and Fish Die-off

From the CSM, "Biologists estimate that between 1,000 and 3,000 birds fell over Beebe on New Year's... Adding to the mystery is an apparent fish kill 125 miles away in the same state. A day before the bird die-off, a tugboat operator near Ozark, Ark., spotted thousands of dead drum fish floating in the Arkansas River. Biologists say the two events are probably not related and suggest that the fish kill – a much more common event than a bird rain – is likely linked to a disease that affected only one species."
