Fact-checking Zinke’s claim that wind turbines kill 750,000 birds a year

HOUSTON -- Interior Secretary Ryan Zinke told thousands of mostly oil and natural gas executives at an energy conference here Tuesday that wind turbines kill as many as 750,000 birds a year, repeating a criticism made by other Trump administration officials.

The bottom line: Zinke is exaggerating the figure beyond virtually all published estimates. But more importantly, turbines are a drop in the bucket when it comes to the human-related causes of bird deaths, context Zinke didn't provide.
