Out of curiosity, what can you do to upset a crow so much? Shoo them?
(Where I live there are no crows, please excuse my ignorance. Only common pigeons, as filthy as they are dumb, and they don't seem to hold a grudge, or think much of humans... or at all).
From the article: "One study found that, between 1941 and 2004, there were just 207 reports of pathogens transmitted from pigeons to humans – anywhere in the world. In all, there were 13 recorded deaths. The true number may be higher, but it would have to be off by several orders of magnitude to compete with the scale of infections from other domesticated animals – particularly some of those with more favourable reputations."
Oh, I don't think pigeons spread disease. I just think city pigeons are filthy and poop all over everything. Frequently mutilated, missing toes or whole limbs. Also frequently run over by cars.
I like the kind of wild pigeons you can see outside cities. I reserve my contempt for city pigeons, which I like to call "flying rats".
I also like crows, but there aren't any (that I can see) where I live. I've seen them in other locations, of course.
The missing toes thing seems related to the existence of polyester thread and similar strong synthetic fibers. I'm vague on why they encounter it a lot - does it make attractive nest material? - and as to why they can't get it off their feet, well I guess pigeons are bad at untying knots, but from what I've observed tangling with constricting fibers looks like the mechanism of action.
Interesting fact you may or may not already know: the pigeons most commonly found around human habitats are feral domestic pigeons. They generally aren't bothered by us because they're bred not to be! Corvids on the other hand are 100% wild (which makes their interactions with humans all the more fascinating, imo).
