A meticulous study recently published by scientists in Leipzig, Germany, concludes that the intelligence of ravens rivals that of the great apes.
Other studies have come to similar conclusions, but this one was especially exhaustive, employing a complex combination of tests designed to measure various aspects of intelligence.
They found, among other things, that four month old ravens have already developed the impressive skill and knowledge of adults, making them incredibly quick learners.
It’s an interesting study in many respects — another step away from older science that assessed all species using, what we are now beginning to see, are very limited human criteria. It was long thought that birds, because of the small size of their brains relative to those of primates, couldn’t possibly be that smart.
Birds and mammals have been travelling down divergent evolutionary paths for lo these hundreds of millions of years. It’s now becoming evident that the mammal/bird development routes may well have ultimately led them to comparable destinations, intelligence-wise. While bird brains are indeed much smaller that our primate ones, it turns out that the many kinds of intelligence are far too complicated to be simply measured in weight and volume.
The German study is also interesting in that it questions the limitation of how valid our human assessment of other species’ intelligence can really be. We inevitably filter the results of our experiments through our particular type of intelligence. The ravens perform the tasks set by the human scientists, but how would humans perform in a test set for us by ravens?
Indeed, it has often occurred to me that I’m proving to be a rather disappointing subject for the ongoing experiment being conducted by our local corvids.
I often see myself reflected in crows and ravens. Not just literally …
… but also in the way I tend to see my own feelings and thoughts reflected back at me. Because I’m not bound by scientific rigour, and because I spend so much thinking about them and watching them, I often lapse into formulating little human-corvid parallels.
Corvids remind me of humans in so many ways — from how we both look sad on wet days to how we care for those we love.
It brings me joy to see these familiar things reflected back at me — but at the same time I realize I really have no idea of what they’re truly thinking and feeling.
They are a deep mystery and that is, in itself, marvellous.
