 Murder Mystery

Lots of dead crows on a highway.

A mystery on why they died.

Struck by motorbikes proven way.

But cars, the crows did move aside.

Why bikes and not cars, question asked.

Bird experts did check into it.

Found that a bird lookout was tasked

Crowing a "cah" when danger fit.

Since "car" and "cah" sounded alike,

Crows heard and flew off of the road.

But since no crow could crow out "bike,"

Bike casualties no longer crowed.

Lack of crow vocabulary

Did solve the murder mystery.
