Bloom, via Chris:Quote:
This innovation spread so rapidly that seemingly overnight
again, the language of a politician instead of a scientist. What's wrong with "in only twelve days, 50% of the birds 30 km away were observed doing the same behaviour?
BTW, I think we are realizing that bird intelligence has been dramatically underrated. Observational learning is the only plausible explanation for this spread, and dogs, whose intelligence we so praise, have very limited or no (according to who you believe) ability to learn by observation. There was a piece on TV showing crows dropping nuts in front of cars to open them
at a traffic light, so that traffic would stop and they could retrieve their booty. How many humans, unfamiliar with cars and traffic lights, would observe the pattern and put it to use? |
