Abstract

Data on callitrichids infant carrying is highly variable, and there is some disagreement over the relative involvement of different group members. Considering that variation may result from different social and environmental conditions it is important to compare data from different environments. The purpose of this study was to compare infant carrying in 11 Callithrix jacchus groups living in two colonies, in the UKand Brazil, or in a field site in the northeastern Brazil. No differences were found in the amount of time that infants were carried, in the three environmental conditions, during weeks 1 to 4, 7, and 10. Fathers and mothers carried infants for equivalent amounts of time in the three conditions, but helpers from natural groups carried infants morethan their captive counterparts. In general, adult helpers carried infants more than subadults and juveniles. The results suggest that carrying is a stable feature in Callithrix jacchus groups, but there is a trend suggestive of an extended carrying period in natural groups. Mothers behaviour were remarkably stable, but fathers behaviour, althoughcomparable, was more conspicuous in captivity than in the field, whatmay be attributed to paternity certainty. Finally, the greater participation of field helpers in carrying is considered as deriving mostly to age of helpers than to group size.
