If you are a little over 14 years old, and your mother is against your trip to the Kenyan Nairobi National Park or to Madagascar, all you can do is come to the zoo in your city, stop at the gate with the sign “No outsiders are strictly prohibited!” and, plucking up the courage to ask: “Are workers needed?” The life of the zoo behind the gate with a warning sign is full of incidents and adventures that you would never guess about when looking at the birds and caged animals from the idle crowd. In this humorous story, Stanislav Vostokov talks about how his career as a naturalist began in the 90s.
