Why should it? It doesn't kill humans, or at least we really don't attribute very many deaths directly to pollution (even though we know it leads to all sorts of cancers and respiratory issues).
After all, if pollution could kill people, why would anybody modify their truck to "roll coal"? That'd practically manslaughter on a very long time scale.
Why would we be using fossil fuels at all, for cars or for power or for lawnmowers or anything, really. The sale and distribution of fossil fuels would be on the scale of committing genocide.
They're built to kill. Crazy good reflexes and eyesight, amazing jump height, claws that grab hold of tree branches, feathers, and skin very nicely. There are a bunch of strays where I live, and they are murdering machines when they don't have a bowl of food plopped in front of them twice a day at their leisure.
Don't know for birds but apparently they can win a fight with snake because they have better reaction time. So maybe something similar is contributing here too
I've watched neighbours cats take out song birds in our garden several times. They're usually too well fed to actually eat them so just "play" the bird gets injured/has a heart attack and dies from that. Something like 1 in 10 homes has a cat on average in the UK. The better fed/kept they are the better they hunt.
The only reason why cats aren't hunting us down right now is because we're too big to be prey. I read somewhere a long time ago that domestic cats have one of the highest predation success rate in the mammalian class. Meaning once they choose to actually try to hunt something they usually get it.
There was a mockingbird that would always attack our cats. The grandma cat had a beak-shaped cut in her ear and a bald spot on her head from this bird that would attack her. I was fortunate enough to witness the occasion where she finally got revenge on the bird.
It had been pecking at one of the grandkittens and then flew away just too low, and grandma cat did a lightning-fat swipe in the air and just kept walking along like nothing had happened, not looking at the bird. The bird kept flying and flapped its wings like 2 more times, then fell to the ground dead, completely ignored by the cat.
It was the most badass samurai shit I've ever seen.
Not sure if you're making a joke, but windows kill birds because they're transparent and birds fly into them not realizing it's there. The rest of the building doesn't really kill birds because they won't fly into it.
mostly musing on the clarification of what a window is, because not all windows are transparent, in fact, the majority of them, i would venture to argue, are not.
