> Mr. Ishihara angrily ordered the city into action after a crow buzzed his head while he was playing golf, city officials said. So the mayor only acted when he was personaly bothered by the issue, apparently.

Golf is a frustrating game. I can easily see ordering the murder of all birds in Tokyo if a Crow messed up my birdie.

I've never played golf, so I can't say. I was more commenting on an example of a politician acting only when he's experiencing the problem first-hand.

I live in Tokyo, and and if I become a billionaire, the second thing I will do (after starting a thrash metal guitar university for girls) will be to commission a Planet Earth II level documentary about the crows here. They are fucking HUGE, they own the city (especially on trash-collection days), and they can go really high. When I moved back here I stayed a few weeks in a hotel on the 53rd floor. There were no pige…

Yeah here in Australia, the neighbourhood magpie is the meanest bird you'd ever seen. But we have been feeding it for years, and it hasn't bombed us in a long time... except sometimes it swoops over my shoulder hitting my head with its wing tip. I'm still on alert during bombing season. Also it still bombs my mum, it hates Asians.

Not to mention the ibises (waste high scavengers with long curved black beaks and no fear of humans) or the giant bats that swoop by your head at night.

Dealing with these crows seems like it would be a good computer-vision/ML/AI/data/drone/"weapons" problem. Killing baby crows in the nest in Tokyo a la [1] would necessarily remain human work, but open-air operations could be done with drones. Would there be a non-lethal approach to harassing crows that would drive them away? If a program chooses the lethal approach, what weapons and disposal methods? How much would…

Armed drones flying around killing crows using machine learning seems like an idea with a huge potential for unintended consequences.

Google may be interested in the problem.

Earlier quoted context omitted.

When a coworker and I were in Ginza we spent an hour or so wandering around Hamarikyu Gardens there. That was the first time I saw one of the Japanese crows. At first, I thought it was a raven, but it was brazen enough to land less than 6 feet away from me, and I got to see how big it actually was. It was taller than my knees. Crows in the Pacific Northwest have this delicate little "caw caw" that they make. It's sor…

>It was taller than my knees. How tall in inches or centimeters?

Probably 28 inches or so.

Around here it's Pigeons, but they seem to occupy the same niche as these Crows. Part of the problem is that not only are they good scavengers, but some people actively feed them causing not only a huge mess (piles of rotting bread dumped on the pavements), but it encourages the birds to congregate and multiply.

Can't we just make pigeons and crows kill each other somehow?

>> They are fucking HUGE

Then you wouldn't like the "crows" near my house:

Haha, this sounds like quite the protection racket. "Sure would be a shame if... someone pooped on your balcony!"

I was able to train the wild city-crows to stand on a certain part of my fence to receive unsalted mixed nuts. Cashews are like crack to them.

Is there a reason why this could this not be brought under control naturally by providing habitat for predator species, like hawks or eagles? Apparently Peregrine falcons have done quite well in urban environments [1]

I was reading Kafka on the Shore and thinking that the frequent mention of crows must have some symbolic value. Then I visited Japan and I understood: Murakami was just being realistic. Crows are everywhere. It is quite ominous to walk through a quiet Japanese park (and I mean dead quiet) and suddenly see a huge flock of crows appear.

Good idea. Though, I suspect the crows would beat the drones. I think it would be an arms-race of sorts. Crows constantly adapting to the drones changing tactics. I would love to see this play out. Here in the States we have Coyotes. The governments of this country have tried in vain over a century to kill off the coyotes but their intelligence and other traits have kept their numbers growing.

They could subsidize the effort with a TV show(someone call amazon), I know I would definitely watch an arms race between drones and crows.
