Zookeepers take care of their animals by acting as nutritionists, behavioral specialists, and, of course, zoologists. They have to know how to keep their animals well-fed, happy, and healthy. Director of Animal Resources and Zoologist Anne Knapp is in charge of the nutritional needs of hundreds of animals at Zoo New England, which runs the Franklin Park Zoo in Boston and the Stone Zoo in Stoneham, Massachusetts. She calculates the amount of food that each animal needs, develops enrichment plans to help the animals fulfill their needs at the zoo, and makes plans for safe rescues for any animal that escapes.
