Evan is super excited to meet a baby jaguar in the heart of the Yucatan in Mexico. There, he also treats a jaguar with a mysterious mass, wrangles a crocodile to tend to its injuries and tries to catch wild flamingoes to tag them for research.

Evan ventures into the Andean cloud forest to check out the llamas of Machu Picchu; while in Peru, he examines a spectacled bear and a vicuña, and tries to save an eagle's eye.
