I think it’s worth it. It’s worth to have a cost of, unfortunately, some bird deaths every single year so that we can have cats. That’s a prudent deal. It is rational.

Facts are facts, I guess.

I am pretty sure all of those pale in comparison to environmental pollution and destruction of nature reserves.

Would be nice if there's data that excludes feral cats, feral cats killing birds are just the natural outcome of the food chain.

Also other collision of separating high rise glass windows vs airplanes

Graph would be better if feral cats were separated from pet cats. As the vast majority of predation comes from those feral cats.

And then there's a few other factors to consider, like cats mostly hunting weaker and sick birds that are less likely to make it to their next breeding season anyway, Vs collisions that will effect all birds pretty equally no matter how strong and healthy they are, so cat predation would have a lower effect on actual population levels.

Now compare migratory birds vs nesting. The error bar on these numbers is massive.
