In this engaging moment from the Frederic Burk School field trip, a young student feeds a hippopotamus under the careful supervision of a zookeeper. With its mouth wide open at the edge of the moat, the hippo awaits a leafy treat—likely lettuce or cabbage, both typical of mid-century zoo feeding routines. During this era, public animal feedings were a popular and encouraged activity at many zoos, especially for children. Zookeepers would often hand out safe, pre-selected food and assist young visitors in delivering it, as seen here. These moments served both educational and entertainment purposes, offering children a direct connection to the animals they were learning about. The scene also highlights the trust and familiarity built between keepers and animals—this hippo appears relaxed and cooperative, comfortable with the daily rhythm of public feedings.
