Sound and its significance for captive primates (1993)

Tromborg, C. T., Mitchell, H., Markowitz, H. et al.

Abstract

Observational research subjecting a pair of cotton top tamarins to the sound of other tamarins and ambient environmental noise yielded significant increases in autogrooming and vocalization while simultaneously yielding significant decrease in allogrooming and scanning. ... The efficacy of this approach of improving the habitats of captive primates will be explored.
