Crows found to be able to use 3 tools

Last year on my blog I posted an entry concerning new research regarding the intelligence of crows.This blog entry can be read by clicking on this link:http://albertan1956.blogspot.com/2009/08/next-time-someone-calls-you-bird-brain.html. Today, I have learned that another scientific study involving crows has been completed, and the results may come as a surprise to you.

Researchers have learned via scientific study that New Caledonian crows can learn to use three tools in succession to reach some food. This behavior has caused scientists to assert that crows possess "an advanced way of thinking." Not only can these crows use tools, they can also learn new ways of acting in order to solve problems they face in their environment. "It appears that the crows have some kind of complex cognitive mechanism that allows them to generate innovation," said Alex Taylor, lead author of the research, published this week in the Proceedings of the Royal Society B.

The society mentioned above has a website at: http://rspb.royalsocietypublishing.org/. An abstract of this research study can be viewed by going to the following website:http://rspb.royalsocietypublishing.org/content/early/2010/04/16/rspb.2010.0285.abstract?sid=83a3db5b-b7f6-4949-a230-31587f54bb05

This video shows an experiment in which , a captive female crow, confronted with a task that required a curved tool (retrieving a food-containing bucket from a vertical pipe), spontaneously bent a piece of straight wire into a hooked shape -- and then repeated the behavior in nine out of ten subsequent trials.





In this next video , Alex Taylor discusses a the findings of a recent study which suggest that New Caledonian crows have the capacity for analogical reasoning. Alex Taylor is a PhD candidate at the University of Auckland.


 Bolhuis and Wynne contrast the cognitive capacities of birds and primates.,,, They also refer to an experiment demonstrating that "crows can also work out how to use one tool to obtain a second with which they can retrieve food, a skill that monkeys and apes struggle to master." Evidently, certain bird species exhibit greater powers of the mind than do apes. Source: http://www.reasons.org/OriginofSoulishAnimals

Thoughts worth thinking about

"Our subconscious minds have no sense of humor, play no jokes and cannot tell the difference between reality and an imagined thought or image. What we continually think about eventually will manifest in our lives."-Sidney Madwed



Laws alone can not secure freedom of expression; in order that every woman and man present their views without penalty, there must be spirit of tolerance in the entire population.- Albert Einstein Too often we underestimate the power of a touch, a smile, a kind word, a listening ear, an honest compliment, or the smallest act of caring, all of which have the potential to turn a life around. - Leo Buscaglia



A person's true wealth is the good he or she does in the world. - Mohammed



Our task must be to free ourselves... by widening our circle of compassion to embrace all living creatures and the whole of nature and its beauty. -Albert Einstein



The best way to find yourself, is to lose yourself in the service of others. - Ghandi



The unselfish effort to bring cheer to others will be the beginning of a happier life for ourselves. - Helen Keller



Aim for success, not perfection. Never give up your right to be wrong, because then you will lose the ability to learn new things and move forward with your life. Remember that fear always lurks behind perfectionism. Confronting your fears and allowing yourself the right to be human can, paradoxically, make yourself a happier and more productive person. - Dr. David M. Burns



Life is as dear to a mute creature as it is to man. Just as one wants happiness and fears pain, just as one wants to live and not die, so do other creatures. -His Holiness The Dalai Lama



Mankind's true moral test, its fundamental test (which lies deeply buried from view), consists of its attitude towards those who are at its mercy: animals. And in this respect mankind has suffered a fundamental debacle, a debacle so fundamental that all others stem from it. -



Milan Kundera, The Unbearable Lightness of Being



The worst sin towards our fellow creatures is not to hate them, but to be indifferent to them. That's the essence of inhumanity. -George Bernard Shaw

Ego's trick is to make us lose sight of our interdependence. That kind of ego-thought gives us a perfect justification to look out only for ourselves. But that is far from the truth. In reality we all depend on each other and we have to help each other. The husband has to help his wife, the wife has to help the husband, the mother has to help her children, and the children are supposed to help the parents too, whether they want to or not.-Gehlek Rinpoche Source: "The Best Buddhist Writing 2005 pg. 165

The hostile attitude of conquering nature ignores the basic interdependence of all things and events---that the world beyond the skin is actually an extension of our own bodies---and will end in destroying the very environment from which we emerge and upon which our whole life depends.
