I had a similar beast get into my airplane factory a year ago. In addition to leaving presents all over the place, I just found out he left one top of my HS that was stored hanging from the ceiling.
I guess it's pay back for his brothers that have had their days cut short by a prop.
I recall three geese landing at my open shop door one day last year.
They proceeded in and marched around the floor and under the wings as if they where inspecting the plane I was building. After that they took a look
at my tools for a few more minutes and then back out the door and and off they flew. I think I past their airworthiness requirements.
