It's difficult to reason about intelligence in this context.

Human intelligence is defined by behavior we humans value. Intelligence tests are geared to measuring these aspects.

Intelligence tests devised by animals would look totally different - and it's quite thinkable humans wouldn't do too well taking them.

Wouldn't assume that animals have less language ability than we humans, unless we totally figured out what other species are really talking about. Unless we do this is just an assumption.
