Behavioural evidence of sex-linked colour vision polymorphism in the squirrel monkey Saimiri ustus. Abstract Text:

Squirrel monkeys, like most Neotropical primates, display a sex-linked colour vision polymorphism. Here we assess the colour perception of 8 Saimiri ustus by a behavioural paradigm using Munsell colour chips as discriminating stimuli. A random variation in brightness assured that discriminations were based on colour rather than brightness cues. Results indicate that all males showed random performances when presented with stimuli which, in previous experiments with human colour-blind individuals and dichromatic non-human primates, proved to be difficult to discriminate. Females behaved as trichromats. The different phenotypes in S. ustus may offer diverse advantages in feeding ecology and are in agreement with the existence of vision polymorphism, as described for other species of squirrel monkeys.
