Nosey neighbour

I went for a walk over to the nature reserve only to find most of it was closed because the footpath was iced over.
I did spent some time just inside and watched great tits, blue tits, a robin, and a dunnock.
A highlight was spotting a grebe (see extra), but I've blipped this curious great tit checking out someone's home.
I went for a run after dark. The feels-like temp was -6c. I didn't enjoy one moment of the 30 minutes I was out there.
