I'm going to call BS on this as the usa has 110 million buildings (the vast majority being single family homes) and in order to kill a billion birds a year as claimed each building would need to kill 9 birds a year on average. I'm sure some do and potentially kill many more, but I live on a rural ranch part of which is a forrest and in the 10 years here we have had one bird strike. If birds are going to strike a window my house seems more likely than most to me.
