Hi Biker and IceAge
Yes I have seen such acrobatics by the magpie too, and the jay once slipped when he hung nearly upside down on the wire - hilarious!
12:49 I have taken these two pictures within 11 seconds, it was like in the mirror hall at the fun fair

15:13 "I want this all!... I want the big piece!... Jayyy, gotcha!"
I promise to post not many GIFs!
Thank you two for your explanations! I have also listened to the song/calls on xeno-canto, and I believe I have heard a willow tit on several occasions outside my home, not so long ago. So I've learned something and will look out for it.
(At least the crested tit has something substantial to identify it :))
