How Many Birds?

OK, so how big is our bird predation problem? Did I get an answer to my question from last night?

Probably. But first a few related items that multiple people pointed out in comments. First, habitat destruction is a way bigger problem than cats, so if you want to worry about the fate of North American birds, that’s #1 on your list. Second, overall numbers are only part of the story. Even if cats aren’t responsible for wholesale decimation of the bird population, they might still be responsible for serious damage to specific species in specific places. Third, although it’s true that it’s natural for cats to kill birds, the cat population in the United States is artificially high thanks to all of us cat lovers who keep them as pets. So the total amount of feline bird hunting is higher than it would be in a state of nature. There’s more in the comment thread if you’re interested.

Still: how many damn birds are there in the United States? John Trapp rounds up the literature here and figures the best guess is around 10 billion birds in spring and 20 billion in the fall. Meanwhile, the aptly named book, “How Many Birds Are There?” estimates 200-400 billion birds for the entire world, which is pretty consistent with 10-20 billion in the U.S.

So, assuming once again that cats really do kill 500 million birds a year, as the American Bird Conservancy claims, it means they kill something like 3% of the total bird population of the country. The error bars are probably fairly large on this number, but at least it provides the right ballpark. So now you know.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
