Maybe I'm finally starting to relate. There's a huge difference between 97 million and 975 million birds.<BR/><BR/>The problem with that 20-30 birds on the monitored buildings is that there are a hell of a lot of buildings that will go centuries without a bird running into them.

There are like 300 million people in the US and maybe what, 50 million households or more? How many of those, then, are apartments? And how many of these are in the cities as opposed to the country?
