For once, the world wide web brings us some non-intrusive, non-exploitative evidence of avian capabilities: Here’s a video of a crow playing on a rooftop, using a circular object as a sled. Tool use has been widely documented among crows, who often both express and develop their intelligence in play. But it’s rare to have the chance to see corvid intelligence in action.
Reminds me of the PBS Nature show last year about crows. I think its title was “A Murder of Crows” (‘cuz that’s what a flock of crows is called, I guess you know). You should be able to Google and find the video at the PBS site.
“Crowboarding” — very cute!
