Video of Wild Crow Tool Use Caught With Tail Cams

Zonk posted more than 6 years ago | from the and-bernd-heinrich-is-well-pleased dept.

Science 203

willatnewscientist writes "Scientists from the University of Oxford have recorded New Caledonian crows using tools in the wild for first time. The footage was captured by attaching tiny cameras to their tail feathers. The wireless cameras weigh just 14 grammes and can be worn by the crows without disturbing their natural behavior. The trick has provided the first direct evidence of the birds' using tools in the wild and may represent an important development in animal behavior studies. 'The camera also contains a simple radio transmitter that reveals the crows' location. This lets the researchers track them at a distance of few hundred metres, so that they can catch the camera's video signal with a portable receiving dish. Up to 70 minutes of footage can be broadcast by the camera's chip, and the camera is shed once the bird moults its tail feathers.'"

That's pretty neat, we have a lot of crows where I work and I've observed ravens at campgrounds which are very well practiced in employing ingenious methods of

I have done it with a model rocket. Kinda cool to see what the ground looks like from the rocket's perspective. It took me a bit to get it to 'swivel' correctly as to stay ground oriented (as well as to stay on the rocket).

A THIRSTY Crow found a Pitcher with some water in it, but so little was there that, try as she might, she could not reach it with her beak, and it seemed as though she would die of thirst within sight of the remedy. At last she hit upon a clever plan. She began dropping pebbles into the Pitcher, and with each pebble the water rose a little higher until at last it reached the brim, and the knowing bird was enabled to quench her thirst.

Those flying pigs used to paint my car every night, especially in the spring. Finally I started to try to train them to go paint the neighbor's cars instead of mine. I use a nasty green laser pointer--it says it's legal, but I sure wouldn't want to get hit in the eye with it. Almost every morning while it's still dark, often before I've done my morning SSS ritual, I go out and bug any pigs roosting over my car with my laser pointer. For the most part, they remember the message now and leave me alone. Started doing this two years ago and my personal crow population keeps going down. They have become somewhat desensitized so that now I have to really hit them whereas before I only had to illuminate the leaves around them, but they do respond.

Have a couple of crows that raise a chick or two in my neighborhood each year. Around May/June they get real cranky as the chicks start leaving the nest and hanging around my backyard.

What is interesting is that the parents will land in a tree branch directly above me and then proceed to pluck twigs and drop them on me.

While a lot of people seem to really dislike crows, I personally am enthralled by their ability to grasp just exactly what sort of thing might make me leave the premises.

Re:Old News (1)

fm6 (162816) | more than 6 years ago | (#20875527)

I don't think that quite counts as tool use. A tool is device you operate. If you use a rock to crack a nut, then the rock is a tool. But if you throw the nut against a wall, you're not using the wall as a tool.

That said, those crows who figured out nuts left in the roadway will be crushed open by passing cars are showing definite signs of creative intelligence. I don't suppose it matters whether their smarts deserve the label "tool use" or not.

Re:Old News (2, Insightful)

lgw (121541) | more than 6 years ago | (#20875771)

Using the environment to solve problems counts as tool use. It doesn't count as tool making, which is a more limited category. Very few species will create a tool to solve a problem, going beyond just using what they find around. Heck, I've known people who aren't that bright.

GrievousMistake (880829) | more than 6 years ago | (#20876163)

It isn't entirely unreasonable to assume that there is some reasoning behind the behaviour, though.
I don't expect them to philosophize about meta-implications or whatever, but take some tool use from the videos people have linked to, picking up a bucket with a steel wire and dropping nuts on roads;
The conditions are unnatural enough that they shouldn't be doing it by instinct alone. The steel wire thing has similarities with digging up insects with sticks, but the road thing?
So if not by instinct, that leaves simple positive feedback learning. But look at the steel wire thing. That's no happy accident. And in the road case, they would have to accidentally fly over the road with a nut, drop it in front of cars, then retrieve it safely, probably multiple times. (Though we may assume that once one crow has learnt it, the behaviour spreads via imitation.)

Summary; I find it unlikely that all of these behaviours are just instinct or feedback learning. Did you have any other likely causes in mind that don't involve reasoning?

Re:So... (1)

Joe Tie. (567096) | more than 6 years ago | (#20875437)

Even aside from having similar behavior documented in the lab, it's not that surprising. The ratio of body mass to brain size, adjusted to the differences in birds, comes out extremely high for most in the corvid family. I don't mean to say it's not an amazing feat, either that of the birds or that we captured it. However, it's nothing that isn't in line with the data from the past ten years or so.

Crows' Response To Surveillance? (4, Interesting)

aldheorte (162967) | more than 6 years ago | (#20875341)

In the book the "In the Company of Crows and Ravens", crows on the researchers' campus could distinguish two researchers out of thousands of people and would continually harangue them whenever they were seen as they were rather displeased at previously being captured and manhandled. I wonder how these crows are responding to surveillance and the ability of the human researchers to track them wherever they go? Are any of them self aware enough to know that the device is associated with humans and remove it? What can we learn from them about operating in a society where people are increasingly under constant surveillance? A paranoid might say that its their tail feathers now, but your equivalent is on the line next. :)

Sorry, I had to ask.

Semi-seriously, imagine the applications for this technology. Trained crows getting shots of places that only crows can go. Imagine video of Ballmer chair throwing events, and other clandestine Microsoft sporting events visible currently only to crows. We don't want that kind of footage locked down in Microsoft Windows Media formats. We want to be able to exchange our crow footage easily via the Internet Archive, so that we can incorporate our crow footage into community-based video projects, such as the Internet Archive's Digital Tipping Point Video Collection [archive.org] , which uses Ogg Theora formats.

Soon, YouTube soon will be hosting crow video feed competitions. We don't want that precious footage locked down, either.

Maybe you should talk to a professional about your hate.


You mean like a hit man? I know Ballmer is annoying, but really -- isn't that taking it a bit far?

@WhatAmIdoingHere:

I noticed the majority of your post was bashing Microsoft for some reason. Maybe you should talk to a professional about your hate.
IMHO, you are being overly sensitive.

Right, so the radio waves from the camera have mutated them into genius tool-using crows.

I can only assume... (2, Funny)

that the crows were using tools to try and pry the cameras off their asses.

What tools? (1, Interesting)

What sort of "tools" did they film? Nothing specific mentioned in the article.

Make sure you watch the youtube video on the right side that goes along with the article. In the video they allude to a number of tools being used, though they only show the crows using sticks to dig out prey, which is still pretty good. Another interesting thing that they mention is that they keep useful tools and use them later.

No, the cameras were the tools the crows were using. The crows were doing a study on researchers that have an obsession with crows.

Think of it, free wireless broadcasting miniature cameras with tracking capabilities. Free spy toys!

Just look around for crow feathers, they'll fall off long after the scientists lose the ability to track them.

Great, Crows using tools! Now they have an even cheaper source of labor to outsource American jobs to.
