Zookeepers do more than just feed the animals and clean their enclosures. Some help design and build the exhibits. Others have to take care of the plants in the animals’ enclosures. And they all have to learn the animals’ personalities and watch for any changes in diet or behavior. Still others work hard at promoting conservation efforts and conducting research projects. And since the animals need care every day, whether the zoo is open or not, zookeepers often work weekends and holidays.
Did you know… that zoos have been around since 3500 B.C.? In 2009, archeologists found what is believed to be the world’s oldest zoo in Egypt. The exotic animals included hippos, elephants, baboons, and wildcats.
Around 1100 B.C., King Wen of Zhou (China) kept a 1,500-acre zoo called the Garden of Intelligence (Ling-Yu). King Solomon of Israel and Judah, King Semirami of Assyria, and King Nebuchadnezzar of Babylonia had private zoos. (Roman emperors also had private collections of animals – unfortunately many of them were used in the arena.) During his military expeditions, Alexander the Great sent animals back to the zoos in Greece.
