Bird or Bat?

I was trying to get a shot of this blue tit just sitting in the tree when it suddenly swung down and hung in this position. It stayed there for at least 3-4 seconds gently swinging and looking around before it just let go and flew away. It made me laugh so much I'm surprised I managed to get a photo at all.

The weather hasn't been quite as bad as I expected, it's been a dull, grey morning but stayed dry, then after lunch I have seen some brief glimpses of the sun and as I look out of the window now (4.15pm) I can see a bit of blue sky - so summer hasn't deserted us yet.

The weekend is upon us again, hope you all have a great one, fingers crossed for more sun :-)))
