I grew up in a seventies contemporary with huge Pella windows on all four sides and remember well how dismayed my amateur birdwatcher parents were about that. The only thing that really worked was hanging black flying owl cutouts in front of them, which spoiled both the looks of the house and the view, it was at the foot of a mountain with a very nice view of large granite cliffs above. Even with that, come mating season the male Cardinals would beat their brains out against their reflection in those windows.
It sounds absolutely wonderful. Even with the owls. We had an oriole that came back year after year int he spring to bash its beak into the kitchen window. Is mating why?
