Lovely house! But I can see their confusion now. I have no idea how to make ceilings and walls, well, everything really, feel like the simple enclosed box design of a typical house room. Gorgeous house though -- hope they can figure out someway to safely navigate.
I know outside birds can accidentally crash into windows, but they do seem to be able to navigate around or to land safely on trees, lamp-posts, bird baths, fences, telephone lines, etc. without injury. Hoping your guys can learn what maneuvers are safe and what to avoid.
