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

@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.

@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)

@Sheril Yup, and "Audubon strongly supports wind energy that is sited and operated properly to avoid, minimize, and mitigate effectively for the impacts on birds, other wildlife, and the places they need now and in the future. To that end, we support the development of wind energy to achieve 100% clean electricity." audubon.org/news/wind-power-an

Also, awhile ago, Benjamin Sovacool did a lot of work contextualizing bird kills per GWh generated across various technologies. grist.org/wp-content/uploads/2

@Sheril This would be more readable if shown in millions. 2,400 vs 0.23 instead of uncountable zeros.

@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.

No wonder birds are so skittish!

Honestly? I've seen half a dozen birds killed by hawks at my bird feeder so far this year, and I've only seen one cat take a run at them, and he missed!

Now how about a fact-check on the BS being spread by the liars at Republican HQ, about windmills and #birds.

@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.

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.
