Cats are natural born killers:
While public attention has focused on wind turbines as a menace to birds, a new study shows that a far greater threat may be posed by a more familiar antagonist: the pet house cat.
The American Bird Conservancy estimates that up to 500 million birds are killed each year by cats — about half by pets and half by feral felines. “I hope we can now stop minimizing and trivializing the impacts that outdoor cats have on the environment and start addressing the serious problem of cat predation,” said Darin Schroeder, the group’s vice president for conservation advocacy.
By contrast, 440,000 birds are killed by wind turbines each year, according to the United States Fish and Wildlife Service, although that number is expected to exceed one million by 2030 as the number of wind farms grows to meet increased demand.
Hmm. If our nation has endured and (dare we say it?) prospered in spite of 500 million birds annually meeting their unmaker in untimely fashion, maybe it is time we trivialized the bird deaths caused by wind farms. The bird people aren't daft on this topic:
The American Bird Conservancy generally supports the development of wind energy, but it argues that wind farms should be “bird smart” — for example, positioned so that they do not interfere with major migration paths or disturb breeding grounds, with their power lines buried to prevent collisions.
