Our National Cat Problem

From a New York Times article passing along the startling news that cats hunt and kill birds:

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.

As it happens, I’ve been trivializing the impact of cats on birds my entire life. I mean, cats kill birds. Bears kill salmon. Birds kill worms. The strong survive and the adaptive fitness of the species is improved. Cycle of life and all that. Why are we supposed to be upset about this?

But despite the fact that my own cats contribute 0% toward this avian holocaust, I understand that I have biases in this area. Maybe I’m taking things too lightly. So here’s my question: assuming that this 500 million number is correct, what percentage of the entire bird population does this represent? I did a bit of desultory googling but got bored before I found an answer. So I’ll put my vast audience to work. How many birds are there in the United States? Do cats kill 10% of them each year? 1%? A tenth of a percent? Just how serious is this national scourge of cat predation?

Thank you!

We didn't know what to expect when we told you we needed to raise $400,000 before our fiscal year closed on June 30, and we're thrilled to report that our incredible community of readers contributed some $415,000 to help us keep charging as hard as we can during this crazy year.

You just sent an incredible message: that quality journalism doesn't have to answer to advertisers, billionaires, or hedge funds; that newsrooms can eke out an existence thanks primarily to the generosity of its readers. That's so powerful. Especially during what's been called a "media extinction event" when those looking to make a profit from the news pull back, the Mother Jones community steps in.

The months and years ahead won't be easy. Far from it. But there's no one we'd rather face the big challenges with than you, our committed and passionate readers, and our team of fearless reporters who show up every day.
