Varanids Counting and other intelligent things

[Starbuck]

one of the methods they use to determine how intelligent a species is uses the recognition of self; they will paint a dot on an animals flank or forehead etc, and see if the animal sees the image in a mirror, recognizes that the image is 'self' and then investigates the dot.

While i personally think this test is selectively efficient for social animals, it may work for monitors. i think this would be really neat to see if monitors have this capacity; you could start by training them that if they touch a target (dot) they get food, then paint the target on the lizards side (or somewhere they could only see if the had a mirror, i.e. their chest?) and then see if the monitor makes an effort to touch the target on 'self' for the treat. The problem with monitors (and crows, and dolphins) is that they don't have hands or trunks (like chimps, people, and elephants) so it is more difficult to quantify an investigatory movement towards the dot vs. simple preening etc. i guess i'd have to do some more research, as I'm pretty sure dolphins and crows have 'passed' this test...
