ABSTRACT
Grooming is an important social activity among primates. In an investigation of its diurnal distribution, all grooming episodes (self-and allo-) were recorded in three families of captive common marmosets (Callithrix jacchus) kept under natural environmental conditions at hourly intervals for periods of 20 min from 0500 to 1800 h, for three consecutive days a week for four weeks. The three families were composed of a reproductive pair and their offspring, with 8, 8 and 7 individuals, respectively. No significant variations were detected within families in terms of days or weeks. However, one family did perform more grooming than the others. The frequency of grooming episodes per hour/per family was higher during the period from 0800-1200 h, with acrophases narrowly distributed near 1000 h, (Family 1 = 1032 ñ 0033 h; Family 2 = 1011 ñ 0013 h; Family 3 = 0945 ñ 0014 h) and lower frequencies were observed at the beginning and end of the active period. The differences between families are probably related to the social dynamics of the individual groups and not to their size
