Looking into this area, birds have it tough. Any number of things may cause their individual deaths or their collective demise. In nature, bird collisions and death are a rather common occurrence. Most of these death happen to younger birds. Overall, about 30% of total first-year bird deaths happen by collision. The biggest cause of bird death however is human infringement due to depleting the environment and collisions with person-made objects. SO how much are we impacting the birds? The following list shows the approximate number of U.S. annual bird deaths and the cause.
Death due to Collision:
300,000,000 - Buildings
200,000,000 - Free Roaming Cats
150,000,000 - Transmission and Distribution Lines
70,000,000 - Trucks and Autos
60,000,000 - Pesticides
50,000,000 - Communication Towers - Doubling by 2010
As compared to wind turbines the bird mortality rate is about 2.0 birds per year per tower. Also, it is becoming more common practice to site new wind farm developments out of the way of migratory paths and the increased size of the turbine blades also minimize the chance of bird death on collision.

Comments: I think an important issue not fully addressed in this article, but highly relevant, is feral cats. What to do with them?
I love cats, and would hate to see thousands of them euthanized wholesale. However, the alternative is the slaughter of countless small mammals and birds, some of which are protected species. And, of course, a feral cat that isn't fixed or killed will simply breed many more feral cats, thus making the problem even worse.
There are not enough shelters to house all feral cats, and there ain't enough money available in local gov't budgets to fix them all.
So...as sad as it is to me and all cat lovers, it seems the best choice is to humanely destroy feral cats, for the sake of the rest of the biosphere... :-/
