Re: Woman who rescued injured crow keeps getting 'thank-you gifts' from birds [video]

I saw some video once about intelligence tests on crows. In one experiment they had a tall but thin glass of water with some treat floating on the surface but it was too low for the crow to reach. So the crow started dropping rocks into the glass, causing the water level to rise, until it could reach the treat.

I was so impressed, I wanted to replicate that. I went to a park around the corner with some nuts to befriend some crows. My plan was to just feed them for a while so they would trust me. But after a few days I had flock of crows following me everywhere through the city. That was a bit too much.
