Google "mass bird deaths" and you can find many such incidents from earlier years... mostly bird flu.

And the fish?

Simply substitute "fish" for "bird" in the above instructions. I.E. Google "mass fish deaths".

It happens. Today we have the Internet... so stories like this can take on a whole life of their own.
