>I would definitely draw a line between this kind of domestication and the domestication of animals by our ancestors for our own survival.

I don't understand why the treatment of other domesticated animals by our ancestors is the metric instead of the treatment of other domesticated animals today. Look at how our treatment of these crows compares to that of cows or chickens on any farm. Can you honestly say that training crows in the wild is the instance where we're crossing some ethical line?
