Santiago Imberti
Birder, Year of the Bird Ambassador, Naturalist

An ornithologist, photographer, fisherman, climber, and writer, Santiago Imberti was born and raised in southern Patagonia, Argentina. He obtained a degree in tourism and later in ornithology, which allowed him to combine his love for nature and the outdoors with his work as a birdwatcher, naturalist, fly fisher, and mountain guide. He has been guiding trips in Patagonia, the Antarctic, and the Arctic for some 25 years. Santiago's passion is conservation and research. Santiago does fieldwork on birds from our ships, and is the Director of Conservation for Asociación Ambiente Sur, an NGO that seeks to protect the environment and educate new generations on a sustainable way of life in southern Patagonia. Since 2009, he has coordinated a project to save the now critically endangered hooded grebe, which is endemic to Patagonia, and to support the creation of Patagonia National Park, a massive protected area that aims to save the grebe and some of the least known habitats in South America. Throughout 2018, Santiago is acting as a National Geographic Year of the Bird Ambassador.
