Conclusion. The work of human caretakers of orphaned baby animals is spotlighted. In Australia, Bev Brown nurtures fruit bat orphans by wrapping them in blankets and bottle-feeding them milk; and Stella Reid cares for 20 kangaroos at her compound, including one that needs to learn how to interact with other 'roos before it can be released into the wild. And in Costa Rica, primatologist Sam Trull prepares a two-toed female sloth for life in the rain forest by teaching it to climb and swim.
