On average birds have the largest brains in comparison to body size. They are very very clever, but then again they had 50 million years head start on the mammals!
.birds have the largest brains in comparison to body size
As noted in Table 7-1 the creature having the largest brain-to-body-mass ratio is Homo sapiens, namely, ~0.022. Dolphins come next (~0.016, which is also the value for H. habilis), followed by the apes, especially the chimpanzees (~0.006). The human brain is about as big as the genes can currently make it and still be safely delivered during childbirth—3 or 4 times bigger, relative to body weight, than the brains of our closest relatives, the great apes. These are data, not sociological sentiments
Crows use tools and show signs of learned behaviour.
Hard to say, I don't speak Crow.Have they improved on the special theory of relativity lately?
Well they certainly have the benefit of experience.Aah well on that basis, I don't speak rock. So lets not underestimate the cleverness of a good flint nodule
Well they certainly have the benefit of experience.
Indeed. But they don't routinely make substances they know are bad for them, ingest said substances, then slowly kill themselves very painfully and expensively either.... but humans do.Indeed - they also fail to enter a trap based on the motivation that another of their type has already decided to do so. Which makes them streets ahead of the average corvid who as the Larsen trap repeatedly proves, do so with a monotonous, stupid, regularity
They don't exploit the planet to a degree that will impact there own species long term survival prospects... but humans do.
They don't work from dawn to dusk so they can buy things to take their minds off the fact they work from dawn to dusk
They don't create elaborate reasons for their existence to seperate themselves from the rest of the animal Kingdom...
Or do they?

Well, that argument can come back to,
"I'm quite sure a rock is happy being a rock"
