| The objective of this study was to determine the size and composition of a group of wild Callithrix jacchus Erxleben, 1777, a small neotropical primate from the North East Brazil. The study was carried out in Dois Irmãos Forest, Recife, Pernambuco, Brazil, in an area of 6ha where this social group of marmosets had its home range. A graded transects system was cut to provide the access and moving during the observation period. To provide an individual identification for the members of the marmosets group and to achieve the objective of this study, two captures were made, with a six month interval between them in a 50x50m² area at the nuclear range of the group's area. The animals were realeased after a maximum period of 24h after traping. We made, during... |

| In this study carried out in the Caetetus Ecological Station, Sao Paulo, southeastern Brazil, a wild group of black lion tamarins was accompanied during 1989 to 1991, to analyse the dietary habits of the species. The scan sampling method was used to gather data. A total of 961 behaviors were recorded, of which feeding occupied 23.3% of the time involved in the behaviors. The major dietary components observed in the black lion tamarins were fruits, tree exudates and animal preys (67.9%, 22.8% and 8.9% respectively). Fruits varied monthly from 47.4 to 97.1 %, being consumed more during the rainy season, while tree exudates varied from 0 to 54.7%, and were consumed mainly during the dry season. The animal prey accounted for 0 to 15.8% of the diet. The most... |

| Foraging in the Black Lion Tamarin (L. chrysopygus Mikan, 1823) was observed in the Caetetus Ecological Station, São Paulo, southeastern Brazil, during 83 days between November 1988 to October 1990. These tamarins use manipulative, specific-site foraging behavior. When searching for animal prey items, they examine a variety of microhabitats (dry palm leaves, twigs, under loose bark, in tree cavities). These microhabitats were spatially dispersed among different forest macrohabitats such as swamp forests and dry forested areas. These data indicated that the prey foraging behavior of L. chrysopygus was quite variable, and they used a wide variety of microhabitats, different of the other lion tamarin species. |
