Vocalization as an Emotional Indicator VOCALIZATION AS AN EMOTIONAL INDICATOR A NEUROETHOLOGICAL STUDY IN THE SQUIRREL MONKEY by U. JÜRGENS (Max-Planck-Institut für Psychiatrie, München, B.R.D.) (With 6 Figures) (Acc. 18-X-1978) The squirrel monkey (Saivniri sciureus) possesses an extremely rich vocal repertoire consisting of more than fifty call variants.

The great number of call variants and the fact that most of them can be grouped into a few classes of continuously varying forms, suggest that these calls do not each have a totally different, discrete meaning but that instead they express shades of more general motivational states.
