Interesting. But my addtion is that we are not outside of the natural world, we are part of it. We think a lot about coyote in the suburbs but we also need to consider that our mania for landscape monoculture has extirpated many species leaving an opening for opportunistic animals such a coyotes.
You're preaching to the choir we are the ones that screwed this world up. I don't deny that at all. We are one of the only creatures that will not only change a habitat to suit our need but totally destroy the ecosystem in the process. Perfect manicured grassy lawns are ridiculous and part of what's killing the bees. That's a whole other topic though.
Cats are causing huge numbers of songbird area extictions every day!!!
I'm not saying that isn't the case in other areas. I think it depends on the number of cats and prey species populations. That said I have worked with and cared for feral cats most of my life. Yes some cats do really love birds and some are good at catching them but most would go for an easier prey species like ground squirrels and rabbits. Most feral cats are tameable and adapt very well to a pet life. Feral cats that are fed will seldom hunt, especially birds. We had at one time a feral colony living in our back yard as we tamed and rehomed the cats. These cats lived peacefully with our dogs coming and going as well as a menagerie of wildlife species.
The yard was fenced in but holes had been cut for wildlife and for the cats. We had nesting robins, sparrows and cardinals, wild rabbits had litters in the yard nearly every year, we also had numerous squirrels and ground hogs. They all lived together and I have photos of multiple animal species living and lounging together within maybe 2-3 feet quite often. The kittens (as the cats were fixed when we were able to afford it) there were 3 litters born while we were there the first before we began taming and working with the ferals. Anyway the kittens would chase the shadows cast on the deck by the birds flying around the yard but not one bird was ever attacked or killed. We were occasionally given gifts by the cats of dead mice or gophers but these were always delivered to the front driveway never in back.
In areas where there are ferals that eat birds feeding them along with TNR can greatly reduce these problems. Also I would like to point out that rats and other creatures are also dangerous to bird populations rats will climb trees to eat eggs.
Many woods are destroyed. Destroying habitat used by song birds along with many other species. Cleared for subdivisions and fields.
My point is that species die off or extinction in very few cases can be contributed only to cats.
I'm not saying you're wrong just that it's not as simple as that and that in many places that's not the case at all. People often hear that and repeat it without having any first hand experience.
Cats can be wonderful and helpful outside. No generally I don't like cats being outside because so many of them get abandoned and starve or have road accidents. It's a bit different when a house cat is let out not all but some cats when put outside can kill for the sport of it. A feral cat will generally not kill for the sport because that expends extra energy that they need to conserve to survive.
Yes that seems counterintuitive to what I said about feeding feral cats helping decrease or even stop their hunting behaviors but they have that mindset of survival. Hunting to them isn't a game it's to eat.
