For my money, I'd rather fly to Puerto Maldonado and take a boat up the Madre de Dios and Tambopata rivers to
Tambopata Research Center. Even jaguars are not uncommon there, never mind red howler monkeys, and 14 species of psittacines. The early morning kaleidoscope of colr with all the macaws and parrots arriving at the collpa (red earth riverbank) to eat dirt is unforgettable. Check out
Rainforest Expeditions - the Center is a lovely rustic place to see wildlife and birds, walk the miles of trails, support the research and training going on there benefitting the Peruvian people, and the nearby Eseieja community. I even saw
Pacaranas here - they had been thought extinct, and my photos were requested by the Smithsonian Insitution (I gave them gladly); a nice thrill.
