Box, H. O., Rohrhuber, B. 1993. Differences in behaviour among adult male, female pairs of cotton-top tamarins (Saguinus oedipus) in different conditions of housing. Animal Technology 44, 19-30.

Animals living in upper-row cages were more active and engaged in more close contact amicable behavior than animals living in lower-row cages. Those located in the half of the room nearer the window were more active than those on the other side. Subjects showed stereotyped behaviour (head bobbing) in a small cage furnished with a nest box and a perch. Stereotyped behaviour was absent when the animals were tested in three times larger cages equipped with a nest box and several perches.
