We found the wasp nest when strimming, accidentally knocked it and got stung. Since then it's grown in size. I noticed that it had been predated this morning but looks as though it might have happened a day or two ago. We know we have hedgehogs, the occasional fox cub but have not seen a badger (we have 3 trail cams). So what would have broken into the nest? It's 680mm from ground and approx 170mm dia at max circumference.
PS. North Wales - if relevant.
Have a possible culprit, see video attached. Have found a reference in British Birds Volume 67 Number 6 June 1974, which includes Great Tit in the appendix list of wasp predators. Unfortunately the video is not evidence of original predator.
Have done that but it's unlikely anything will have another go until any grubs hatch. Will have to wait and see.
Caught a Great Tit on camera, added video to original post.
Well done!

Update, we were away yesterday but the Great Tit returned again (luckily later so no sun glare). I am 90% sure that it was probably the original raider. A pair of Magpies went by but showed no interest in the nest at all.
Great detective work! That's what naturalists do, ideally.
