At ONWILD, we believe that knowledge is the key to conservation and to forming a true connection with nature. Guided by this mission, we created our collection of field guides dedicated to Portuguese wildlife. Each book is the result of years of field observation, research, and a deep passion for the natural world, offering accessible yet accurate information for naturalists, photographers, and nature enthusiasts.
Our guides feature detailed descriptions, high-quality photographs, and distribution maps, making species identification in the field easier and more intuitive. From birds and mammals to amphibians and reptiles, ONWILD books are essential companions for anyone looking to explore and better understand the incredible biodiversity of Portugal. With a practical format and user-friendly approach, they are perfect for taking on any outing or expedition.
Discover the fauna of Portugal through our eyes — and bring along a tool that will help you observe, photograph, and protect our wildlife.
