A bird?
A type of worm?
A fruit?
Answer below:
Back in 2005 I was traveling in Slovenia. While touring a nice forest it started to rain so I found myself sharing a small road shelter with an old local.
The man drank quietly from a small plastic glass, that was wet from the rain, and then he took from his bag a few fruits and placed them on the glass.
So, if you guessed fruit - good call.
BTW - I have no idea what fruit it is, if you know, please share it
