I really believe that, when people ask if some organism is "intelligent" or "conscious" (answer is usually No), they're just asking how similar it is to a human. Intelligence or consciousness is not a Thing; it's just a set of behaviors that have proven adaptive to some species. Crows have somewhat more of those behaviors than we'd thought.

By way of example, many animals have much better smell than we do because that is adaptive for them, and it's not quite as much of an advantage for us.

As for what kind of "consciousness" they have -- they have what they need. We can't know what it's like to be a bat, because we're not bats. It's probably not like being a flying human with sonar, but we'll never know.
