Charles and Jon interview Regina Ribeiro, arguably Brazil's top mammalwatching guide. Regina talks about her journey to become one of Brazil's first female wildlife guides, and runs through her own list of the Brazilian Big 5. She also talks about what can go wrong when you have to take a minibus along the Transpantaneira. Here is the YouTube trailer.
