Communication and Perception
Grooming is a way for E. fulvus to establish and maintain social bonds. Their unique method of grooming is a result of their 6 lower procumbent teeth that form a dental comb. This instrument is used to groom their own fur and that of the other members in the group.
Communication is achieved by both olfactory and vocal means. Olfactory communication is extremely important and is made possible by the scent glands located at the wrist throat. This type of communication is used for transmitting physical state, location, and individual recognition.
The sounds brown lemurs use for vocal communication have been described and partly deciphered. A nasal sound used in maintaining group cohesion has been described as 'ohn'. A 'cree' or high pitched sound is used as a territorial call, and 'Crou' is the alarm call of this lemur.
In addition to these forms of communication, body postures and facial expressions are likely to be important visual signals.
