Neurotic mother thought #267492

I've noticed a lot of flattened birds on the road in my area. I've actually seen a bird become road kill once. Can we say "explosion of feathers?"

My main concern is this: with all the flattened birds around, how am I going to know whether or not to report another oubreak of West Nile virus to the CDC? How do I know that these birds weren't run over by an SUV postmortem???
