In the U.S., recent annual estimates of bird deaths due to:

Cats = 2.4 billion bird deaths

Collisions from building glass = 600 million bird deaths

Land wind turbines = <200,000 bird deaths

Some politicians claim wind turbines “kill all the birds.”

But… they’re not really worried about birds. Rather, they prefer we stick with oil & gas over renewable #energy.

Infographic: What Is Killing U.S. Birds?

This chart shows the estimated range of annual human-caused bird deaths in the U.S., by source.

Statista Daily Data

Popping on the visualization (also linked above) bc there were a few questions about the data.

This chart displays the US Fish & Wildlife estimates of annual bird mortality in the U.S. from several human causes. /2

It shouldn’t need to be said, but given some comments, let me be clear: This is not a post about harming cats.

The point is that special interests have been framing the narrative around renewables in ways that aren’t evidence based to influence public opinion away from supporting wind turbines & other technologies.

But we need to decrease our dependence on fossil fuels to address #ClimateChange. /3

@Sheril (But one should also keep one’s cats indoors, both for bird health and their own.)
@Sheril what about nuclear and geothermal?
@ludiusvox @Sheril
I haven't seen the data, but I would guess the number for annual bird mortality in the U.S. due to nuclear and geothermal is pretty small. :)

@Sheril
I adore cats & have 4, but I don't think we can avoid a discussion about all the meat they require. And I go through so many aluminum cans I feel like an Alcoa subsidiary. Spay/neuter!
@Sheril while agreeing with the basic premise (wind turbines kill a suprisinglow number of birds) I do wonder if we are ignoring the "quality" when we just look at the quantity. I would imagine that cats mainly catch small, very common birds (sparrows, etc) while the wind turbines may kill a larger proportion of the bigger and more endagered species (birds of prey and the like).
Would be nice if there are numbers to back me up or prove me wrong.
@swaldorff @Sheril An interesting question
@Nonya_Bidniss @Sheril
Some interesting solution proposals:
Make the rubines more visible to birds:

Or swiutch them off when a (big, valuable) bird approaches (either detecting the transponder endagered specias carry or using a radar+AI system)

Could stripy wind turbines help to save birds from their blades?

We need to see like birds in order to protect them, say the ornithologists suggesting a ‘simple’ redesign.

@swaldorff @Nonya_Bidniss @Sheril Or you could add #AI to wind turbines, and if that causes a problem, find a tech solution to control the AI which controls bird deaths. https://www.identiflight.com/how-it-works-2

Have only inside cats….

@Sheril This would be more readable if shown in millions. 2,400 vs 0.23 instead of uncountable zeros.
@Sheril Now add pesticides & loss of habitat

@Sheril So frustrating that a meta analysis from a decade ago that was mostly guess work and approximation is still being sited as an accurate rate of cat caused bird deaths. They even state in the appendix that while most bird deaths are attributed to feral cats "no empirically driven estimate of un-owned cat abundance exists for the contiguous U.S."

Here is a break down of why the data is essentially intentional misinformation from the NIH

@BlinkPopShift @Sheril thanks for sharing, this is interesting and relevant.
I'd just add that the original argument that wind turbines are not the worst, most evil bird killer ever, probably still holds given the orders of magnitude.
Also the review states that pressure from cats is not a problem if populations remain sustainable, which is valid in theory; but we know that bird populations are in fact dropping fast in most places, so any pressure that can be avoided ideally should be.
@Sheril yes bit wind turbines is killing big birds such as eagles and condors, a cat cannot harm an eagle. Eagles are really common up north where solar power doesn't work and they want to use huge wind turbines that are ugly.
@ludiusvox @Sheril this person has an agenda

@simSalabim @Sheril

Oh I been protesting this in outer-banks right next to the wildlife sanctuary in North Carolina, the election swing a win or loss by 10,000 votes and they approve these horrible projects with slim margins.

@Sheril Humans have removed most predators from our landscapes allowing small birds to flourish in a way they would not naturally be able. Despite the cat predation, we don't see any small birds in danger of extinction.

Cats pose no danger for condors, and condors are unlikely to be flying into glass buildings. So we would want to know what kind of birds are flying into the wind turbines. If condors ... that's a problem. If seagulls ... not so much.

@Sheril
The thing is (and I'm not going to even attempt to engage with the numbers as a lot of replies are, since I don't have the backing), it's never been about the 'reality', just the perception.

Saying 'This kills birds', they're hoping for a visceral emotional reaction, like when it was discovered that 'cute baby seal in oil' got a stronger reaction than 'billions of animals dead'.

Of course, I -personally- hate birds viscerally, but I support keeping them alive. Away from me.
