More squatters, not so welcome this time

It might not be very clear what this is. It is a picture of a small rabbit hutch almost completely filled by a wasps nest, the circular gray thing in the middle.
I am very impressed by their home building abilities and , as the wasps are not causing me any problems, I do not intend to do anything with the nest.
One problem I do have is trying to remove the plank I used to hold up the lid of the hutch whilst I took this blip. The occupants will probably not be too pleased to be disturbed again.
