It's been posted many times. C'mon socko, do a thread search. They are all in the enviro threads.
Sorry, I've been frequenting a forum that required citations for such assertions.
Here's something I found on goggle:
Man-made structure/technology
Associated bird deaths per year (U.S.)
Feral and domestic cats
Hundreds of millions [source: AWEA]
Power lines
130 million -- 174 million [source: AWEA]
Windows (residential and commercial)
100 million -- 1 billion [source: TreeHugger]
Pesticides
70 million [source: AWEA]
Automobiles
60 million -- 80 million [source: AWEA]
Lighted communication towers
40 million -- 50 million [source: AWEA]
Wind turbines
10,000 -- 40,000 [source: ABC]
HowStuffWorks "Do wind turbines kill birds?"
I thought, perhaps, this was your source, and perhaps you inadvertently added a zero to it. But perhaps not.
I noticed you did cite the number of birds found in the first week of BP. Since that number was surprisingly low, it that why you cited anyway?
Like I said, I'm used to having to prove my asserts, particularly in scientific threads... socko.
