No worries. It's all good. My only point was that I've heard from other beekeepers that shrews do at times get through the standard commercial metal mouse guards.
When I first used half-inch mesh for mouse-proofing, I did it because I saw Michael Palmer do it in Vermont. But he bends the mesh through the bottom entrance to make it smaller so mice can't get through it. Then I met a local beekeeper who told me half-inch mesh attached straight on works fine. And it did for a few years until I encountered shrews.
To bring us back to the original topic of this thread, body parts, wings, legs, hollowed out abdomens --- those are excellent signs of shrew predation in my experience.
