Day123/17. The mystery solved.

After yesterdays picture we spotted the culprits. The Grey Squirrels were the little rascals eating the flowery catkins on our Oak tree. The trouble was, as you can see, to get to the flowers they bite off the whole new growth, have a munch and then throw the remains onto the lawn.
Not sure what we can do to stop them, we counted 5 in the tree at one point. Hopefully the tree will endure.
