It is not raining. It will rain.
On a sandy track through the forest, the footprints of a giant bird.
Possibility 1: a bored child with a stick
Possibility 2: a giant bird

Possibility 1: ravens talk to themselves
Possibility 2: ravens have mobile phones (with headset, of course)
Conspiracy theory: a giant bird has appeared in the forest, and the ravens are leading the investigation.
