An ornithologist, photographer and writer, Santiago 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 bird watcher, naturalist, fly fisher and mountain guide. He has been guiding trips in Patagonia, the Antarctic and Arctic for over 20 years.
However, his main passion is conservation and research therefore in the off-season Santiago does field work on birds, mostly in southern Patagonia and is the Director of Conservation for Asociación Ambiente Sur, an NGO that seeks to protect the environment and educate the new generations on a sustainable way of life in southern Patagonia. Since 2009 he coordinates the project to save the now critically endangered and Patagonian endemic, Hooded Grebe; and also the creation of a new national park, a massive protected area that aims to save the grebe and some of the least known habitats in South America.
His many articles and stories have been published in scientific journals and popular travel magazines. In the last years, three of his books on birds and Antarctica have been published, he has become a certified wilderness first aid responder and, since his singing abilities are rather poor, he has produced a couple CDs of the beautiful bird sounds of South America, Patagonia and Antarctica.
