By jove that does sound like a Cyanistes teneriffae
I'm working away in my office here and I'm pretty sure I hear birds twittering, lots of birds. More birds than are outside my window this morning.
Actually sounds quite wonderful, all the bird song. Then I shift window screens over to another area I'm working on and I notice that the LambWatch website is open and running a live video/audio feed from a sheep farm somewhere in the UK. That's where the bird noise is coming from, somewhere in the United Kingdom.
And actually it's kind of cool, so I've let it stay open and I'm listening to birds singing on the other side of the Orb.
