I was thinking about the robot which
picked up white litter (linked). It would
have trouble moving over uneven and
vegetated terrain. It would wind up
getting hit by a car.
But the white sensor could still be used.
envision the robot as having a hopper.
When something white was
robot would sense it and dispense a tiny
pellet of food.
A group of young grows would be taught
how the machine works. They could find
something white and drop it in, then
receive food. When done, the robot
be parked in various area, and the crows
would scour the surroundings to put
I suspect that wild crows would pay
attention and learn this way as well.
Crows have culture. Ultimately, cities
could be kept clean by their resident
and a few robots full of kibble.

Startup Plans To Clean Up Cigarette Butts Using Crows

||crows are cool... but pigeons! Fuck yeah.
||That would be hilarious, 21 quest. Even after the program were discontinued due to the disappearance of anything not bolted down, the army of crows would superstitiously keep trying to replicate their successes by placing random stuff in dumpsters, convertibles, old refrigerators. No object is safe!
||But hilarious for me! I have an MP3 player I got on ebay for ten bucks!
||Especially hilarious when I build a papier mache mockup of the robot, and suddenly have lots of iPods. Which cost me birdseed.
||I like it. I like it a lot. We ought to do a lot more
of this kind of thing--getting rabbits to cut and
fertilize our lawns, getting pigeons to deliver the
mail, and getting dogs to not crap on the carpet.
||(I have low expectations for dogs, because I own a
phenomenally stupid beagle. (Yeah, yeah, I know,
all beagles are phenomenally stupid, but this one
is stupid even by beagle standards. She's so
stupid it borders on cute.))
||There are really huge numbers of crows living in cities. I think this is a recent thing - occurring over the past few decades. Maybe it is a phenomenon similar to the colonization of Europe by rats in the early middle ages. In any case, it would be good to get some useful work out of crows and they are certainly capable of it.
||Yes, over the last decade north county San Diego has come to be ruled by clouds of crows. Anything to use this resource would be good.
||Thanks for that link, swimswim. That made my day.
||I really like your idea (I like a lot of your ideas,
Bungst) and after first reading it I went on to read a
bunch about New Caledonian and other crows. It
made me want to build a contraption to do
something like the idea describes. There are
certainly enough crows in my neighborhood to give
it a try!
||I was pondering recently how this might be done.
I think a nozzle pointing down with a color
detector. Pointing down means the crows cannot
clog the machine with random stuff. When the
color detector detected white the vacuum would
turn on briefly and suck the thing up. A piece of
kibble would come down to the pecking bin at the

||Well, as they say, train the trainer. If you coached one and allowed him to show the others, they'd catch on.
