Communication inGalago crassicaudatus

  • Jocelyn M. Tandy


The olfactory, visual and, auditory communicative behaviors of a colony of feralGalago crassicaudatus (four males ad three females) observed over a two year period are documented. The enclosure was constructed to simulate a natural environment, but all stimulus possibilities available in the wild were not present and several new ones were introduced. It is not known how many of such differences may have affected the animals' behavior, however not all behaviors observed in the wild appear in the lab.

The characteristics of several calls are described in detail and illustrated with sonagrams. These include an agonistic call, a sexual call, a possible alarm or mobbing call, a possible territorial or spacing call and a “low grunting sound” which appears in contexts of sexual and territorial calls. Compared to “higher” primates these galagos exhibit a small number of vocalizations. The communicative system appears directly correlated to social organization.
