Outside my window, on a beautiful sunny day, it sounds like someone is spinning up a particularly noisy hope pro II hub – 3 seconds, 1 second, 12 seconds….
Yet, when I look outside – nothing!

It really doesn’t have the chirp of a cricket.
It really does sound like a freehub spinning up…

Intelligent (or not so) guesses as to the sound – I’ll explore after morning surgery if it continues…

Squirrel in your loft.

A bee in your bonnet?

Yeah, dubstep turkey was pretty low on my list of likely culprits…. but I shan’t rule it out… 😀

Baby Robin?

That wren recording has to be the worst bird recording ever.

Good call on the beetle. We heard a ticking noise comming from an old wardrobe. Got back from holiday to find a massive exit hole.

I’ve never heard a wren make those road traffic noises before…
