The Brazilian Squirrel Guerlinguetus brasiliensis ingrami (Rodentia, Sciuridae) is commonly observed in the wild, yet its population parameters are poorly known because this species rarely captured with traditional live-traps. Here we evaluated of G. b. a 3-year capture-mark-recapture study at Serra da Bocaina National Park, Rio de Janeiro state, Brazil. Population were using Jolly-Seber model POPAN and Minimum Number Known to be Alive (MNKA). size estimates ranged between 3.2 ± 2.4 (mean SE) 51.3 15.0 individuals based on POPAN, 2 10 MNKA. Our density (1.3 74.3 individuals/km )were similar those documented previous studies carried out Atlantic Forest. Monthly survival was high (0.94 0.02) capture probability low (0.16 0.05), probably reflecting trap-shyness. evidences importance unique data presented for increasing basic knowledge species.
