Summary
In Bolivia during May-June 2023 I saw +57 mammal species (as listed below) and 14 reptile species. Larger mammals included Chacoan Peccary, Jaguar, Puma, Ocelot, Tayra and Madidi Titi Monkey. Small mammal highlights include Foster’s Punare, Vargas Llosa’s Bristly Mouse and a roost of Lesser Bulldog Bat. In southern Bolivia I was with Stuart Chapman and we used tour operator Nick’s Adventures for the main sites which included Jaguarland (a private ranch) and Kaa-Iya NP. In northern Bolivia I flew into Rurrenabaque and visited Sadiri Lodge and Las Tortugas Lodge.

B.  MAMMAL LIST
