I just came back from Japan, crows all over Tokyo, but they are pretty much disappear after 9 AM, if you're an early riser you will see them everywhere!

#12Crows are very underrated in terms of intelligence.
Not really. The Corvidae family of birds are widely known as some of the most intelligent animals.

#13> 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.

#14>>> The crow explosion has created a moral quandary for Japan, a nation that prides itself on nonviolence and harmony with nature, because culling programs are the only truly effective method of population control.
No. Culling something like city crows is insanely difficult without resorting to poisons, a very dangerous option in a city. Crows are a problem all over the planet. Get some hawks, or whatever species of raptor is native to japan. A few pairs of nesting peregrines will keep the population in check. More importantly, the presence of raptures in an area changes the behavior of prey species. The crows will be far less bold.
Except eagles. Eagles are wimps. I see them harassed and chassed away by crows almost daily.

#15A good start would be to use trash cans. At night people put out bags of trash on the street to be picked up in the morning.

Interesting, I only saw a few over a period of a couple of weeks in Tokyo.

#17The city of Portland, OR hired falconers and their birds to keep the crows from hanging out on certain streets downtown:

#18Isn't it called a murder? A murder of crows.
it is. English is really rich in this aspect. My favourites are:
- A Conspiracy of Ravens
- A Vortex of Vultures

#19Dealing 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 a program cost, and would that cost be offset by savings on the extra garbage-collection efforts that crows cause in [1], and other factors? How would crows adapt their strategies? Could similar approaches be used for rats in NYC, for example? Would there be downsides to a NYC without rats, a Tokyo without crows?
How long till technology would make a program like that viable? If Google is working on automated drone human targeting, the crows-in-Tokyo seems like a much more constrained problem.

EDIT: technological viability.
