This book offers one of the most extraordinary events that occurs every so often in nature: migration in the animal kingdom. The author, Celedonio García-Pozuelo, whose curiosity leads him to study everything that moves and lives, takes us magically by the hand into each of the mysteries of the phenomenon of migration, and shows us the scope of the journeys undertaken by some animals on our planet. The author goes in depth about these phenomena with extensive knowledge and skill, using precise yet educational language, presenting information in paragraphs that stand out, so that their reading is very appealing and can be discussed among parents and their children.
