The first day (after two weeks of Christmas holidays) I was able to visit the forest I couldn't
because it was too windy.

The next day the wind had settled and lots of branches had come down, branches that could
have ended up on my head 🍃

This little bird's nest also came down. I took it home, after which I spend at least 20 minutes
shaking all the vermin and spiders from the nest 🕷

It's next to impossible to find out exactly what bird build this nest but someone on the
facebook Determination of Dutch Birds page suggested: garden warbler, common
whitethroat or the eurasian blackcap.
