After years of preparation, my PhD student George Olah finally got what he wanted. A special permission from the government of Peru. The 50+ page document gave him access to the Holy Grail of parrot researchers: the Candamo Basin, in the Peruvian Amazon. A place where wildlife exists without any human disturbance since the beginning of times. Surrounded by the foothills of the Andes, the Candamo Basin hosts one of the very few uninhabited tropical rainforest of the world. Not even native tribes had settled here and decades had passed since the last camera team dared to sail the hostile rapids of the Candamo river.
Wildlife Messengers produced a stunning documentary movie, The Macaw Kingdom, about our research expeditions. Watch the trailer below or the full documentary.
