Binti Jua, a gorilla at Brookfield Zoo, was carrying her own 17-month-old baby on her back. A 3-year-old boy fell 24 feet into her enclosure and landed unconscious. She crossed the pit and cradled the boy against her chest. Her infant still on her back, she carried him to the keeper door. Six other gorillas were in the enclosure. The boy made a full recovery.
