About the book: 1963 / “The fish are singing in Ucayali" - a story by the famous Polish writer and traveler Arkady Fidler about an expedition to the upper reaches of the Amazon in 1933–1934. The Amazon is a world of wonders, a country of virgin tropical forests, a land of the unknown, mysterious and beautiful. But this idea is not entirely correct. And this is the fault of those travelers who, being enchanted by the luxurious nature, saw only the exoticism of the forests, the enchanting beauty of orchids, the incredible diversity of the animal world and the greatness of the water element. Fiedler’s book “The Fishes Sing in Ucayali” gives a more complete and vivid picture of the Amazon. Imaginative and lively and at the same time precise and concise language makes this book interesting and easy to read. It feels as if you yourself are a participant in the author’s journey and see everything that he describes. Magnificent pictures of tropical nature follow one another. The story about strange plants, about the smallest birds in the world and the largest butterflies, about huge lizards and singing fish, about impenetrable wilds and the greatest river in the world, the Amazon, will be remembered for a long time. The writer does not forget about the people inhabiting this amazing region, the riches of which are still being used very weak. The book will be read with enthusiasm by those who are already familiar with the brief description of this expedition, designed for young readers, published under the title “Call of the Amazon”».
