Translocation and radiotelemetry monitoring of black-tailed marmosets, Callithrix (Mico) melanura (E. Geoffroy in Humboldt), in a wildlife rescue operation in Brazil

Five black-tailed marmoset Callithrix (Mico) melanura (Primates - Callitrichidae) individuals were monitored by radiotelemetry as part of a project on translocated wildlife affected by flooding the Manso River reservoir in the state of Mato Grosso, western Brazil (14 degrees 52' S and 55 degrees 48' W). The animals were monitored for eight months from October 2000 through August 2001. Only one death was recorded among the translocated animals. Two pairs established their home ranges in the new area, after some exploratory behavior. The new home range sizes varied from 0.72 to 4.27 km(2). The home ranges of male and female overlapped in the case of both pairs by 0.59 to 2.30 km(2). Trips were always made in pairs and not individually. The results indicate the feasibility of a successful translocation program for this species, as long as the animals are translocated to a similar habitat nearby.
