Chimpanzees are known to 'fish' for termites, which is a fairly complex behavior involving a hidden food source, so I'm not sure the test is obviously biased toward ravens (unless they also administered the Raven's Matrices). It would be interesting to see if there were any sex-related differences in performance, as it is female chimps who do most of the insect hunting, and teach it to their daughters).
