I found a birds nest with one egg in it, constructed on top of my PA-17 engine's cylinders this morning. It wasn't there two weeks ago.
I only have a few Zeuss fasteners to twist. If there were a couple of dozen screws, or wired hinges to undo and do up again, there might be circumstances where it would not have been found.
I hope you grounded the 'plane,you do know its illegal to remove the nest whilst there is an egg in it ?
Just carry on paying the hangarage and insurance and send the bill to the RSPB or whoever.
When I took a fuel sample yesterday a tiny bug came out with the fuel. It clearly wasn't compatible with 100LL and quickly kicked the bucket so must have been hiding up in the Curtis valve.
