Male squirrel monkeys may display the erect phallus under various conditions of courtship, aggression, and salutation. One variety will display consistently to its reflection in a mirror. Such display has a typical pattern and can sometimes be triggered by reflection of but one eye. A mirror display test has beenz designed for experimentation on the brain. 
Preference for mirror image stimulation in goldfish (Carassius auratus)
Ten goldfish, given a continuous choice between orienting toward a mirror or another conspecific behind Plexiglas, exhibited a distinct preference for mirror-image stimulation, implications for theories that attribute the appetitive properties of mirror confrontation to the fact that it elicits an aggressive display.
Mirror responses in a group of Miopithecus talapoin
This study applied a rigorous methodology that took into account habituation of subjects to the mirror as an object and to the experimental situation, and found that the talapoin monkeys in the study showed a prerequisite for self-recognition, namely comparing their body parts to the image of these in the mirror.
Squirrel Monkey Communication
There are significant gaps in understanding the functional significance, ontogeny, and intraspecific variability of many common communication patterns in this well-studied squirrel monkey species.
Motivational Properties of Mirror-Image Stimulation in the Domestic Chicken
Brief exposure to a mirror was found to be an effective means of inducing baby chicks to ambulate down a simple straight alley. It was also shown that visual access to a mirror was more effective
Preference for mirror-image stimulation in differentially reared rhesus monkeys.
When given a choice between viewing themselves in a mirror or looking at another monkey, feral rhesus monkeys seemed to prefer viewing the conspecific. On the other hand, surrogate-reared animals
Responses of capuchin monkeys (Cebus apella) to different conditions of mirror-image stimulation
Group-living brown capuchins were given mirror-image stimulation as follows: (1) mirror 1 m away; (2) mirror attached to the cage-mesh; (3) angled mirrors creating a deflected image; (4) small mirror
Visual sensitivity: significant within-species variations in a nonhuman primate.
Among squirrel monkeys (Saimiri sciureus) there are significant sex-related differences in visual sensitivity, and a sample of males was found to be substantially less sensitive to long-wavelength light than a group of females tested in the same way.
Mirror-image reinforcement in monkeys
Using a successive discrimination task, 4 pigtailed monkeys, 1 Japanese macaque, and 1 rhesus monkey were given 54 separate 60-sec. opportunities to open an instrumental door on a random 50% schedule
