The crows cawed again, their voices harsh and ominous.

A crow cawed loudly, then launched itself from a rooftop and flew away to the north.

The day grew hot and crows cawed in the river bottoms.

A crow perched upon an opened venetian and cawed lustily.

But these crows don't caw and cackle, they whisper: "What if?

Above him the crow suddenly cawed and danced along the rooftop.

A crow cawed from high in the bare branches of a dead spruce.

The crow cawed again, as if mocking him.

A crow cawed in one of the trees, unless it was a rook.
