In 1840, Jean-Baptiste used the inheritance of his parents to travel the world. This is how he ends up in Peru, a country full of undiscovered Inca treasures and lush nature. He searches for hundreds of animal and plant species in the rainforest, which he collects and sends to the newly established Natural History Museum in Brussels. The crested wire hummingbird was discovered by Jean-Baptiste and has since been named Discosura Popelarii. Arnout and Jasper use great resources to see the little animal. Jean-Baptiste's diary was lost over time, but fortunately Arnout found notes. In this way he brings a piece of national history back home!
