Well, I am from Brazil and around here you can find plenty of species, specially if you go North (to Amazon State) or South-West (the Cerrado and Pantanal area).
In Amazon you will find birds, monkeys, jaguars, some deers... but most of it will be birds and monkeys.
In the Pantanal/Cerrado area you will find water birds, alligators, big rodents like the capybara, big snakes (100 Kg +
) , bigger deers and with a little luck one jaguar. It is a nice place to fish if you like too..
Here is a little bit more information about Pantanal:
