> crows know what they know and can ponder the content of their own minds, a manifestation of higher intelligence and analytical thought long believed the sole province of humans and a few other higher mammals.
I've always found the common thought that only humans and a select few of other animals are the only ones that posses higher intelligence to be incredibly arrogant of our species. Why wouldn't they have higher intelligence? As far as I can tell, it's because there's no simple test that could be applied to confirm or deny whether higher intelligence exists within an animal, so we then jump to the conclusion "Because I can't prove that they do have higher intelligence, then they must not have higher intelligence" - logic doesn't work that way! Glad to see some people are willing to dig a little deeper and take the time to show that crows do have this capability.
