A 2016 trip to the Central Amazon?
This should be a fabulous trip (if you have traveled with Fiona before then you know that that is no exaggeration). Just check out the trip report from there in 2014: Central Amazonia
Highlights from other trips to the area include Maues’ and Gold-and-white Marmosets, lots of other primates I have never heard of, a bunch of Porcupines and Tree Rats and shed-loads of bats. Its very tempting.
