How comparable is the intelligence of crows, dolphins, octopi and non human apes? Somewhat or not at all? There seem to be a host of things that each of those can do. Can apes do all of those things and the other groups just a few things each? Is there a huge leap of separation or does the leap come between us and them? Is it in any way quantifiable?

Humans have so far failed all the tests that crows set up to measure their intelligence

I was watching some crows eat some food in a parking lot yesterday. The first one landed next to a tiny morsel, investigated it a bit, then did a head bob thing while looking up and making what sounded like a cross between a hoot and a caw. Another crow swooped in about ten seconds later and they poked at it a bit. Then a lady walked over towards them, they flew away, and she dumped out her half eaten to-go meal in the parking spot. Too easy.
