A news report is out today on an Environment Canada study of how many birds are killed in Canada each year, and why. Pro-wind power commenters are gleeful: see, they say, it was cats all along!
Well, we knew that.
The fact that the majority of bird deaths is supposed to be from cats, wild and domestic, does not, however, dismiss or minimize the damage being done to birds by large-scale wind power generating machines or turbines.
Here’s a difference: wind turbines typically kill larger birds including raptors such as eagles and red-tailed hawks. Because these large birds have a life expectancy of as much as 20 years, or more, each raptor killed means the deaths of generations of raptors with it.
These birds are critical to the environment, preying upon rodent pests.
So, of course cats, and power lines and buildings are responsible for thousands of bird deaths each year—but that’s not an excuse to kill more with industrial-scale wind turbines put right in the path of migratory birds.
