Teenaged Canadian bird nerd comes up with a compelling product to prevent window strikes. My old office was a mirrored building in the middle of a woodland – a dark joke for the neighbourhood birds, who would plow into it with sickening regularity, despite the presence of falcon silhouettes. As one poster points out, the kid’s invention is best applied to the outside of the building – our old office, I think, would make an excellent beta testing ground.
