Julien Mazenauer

Julien Mazenauer lives in Neuchâtel, Switzerland, with his partner Hélène. Birding in his home country since the early age of 10, he quickly expanded his experience across the Western Palearctic, which he has covered extensively. He started guiding short excursions in Switzerland at the age of 17 and then full tours in the rest of the world. His first trip to Costa Rica as leader was like a revelation and he decided to work towards a career in bird tour leading.

Julien is currently finishing his master’s degree in the conservation biology division at the University of Bern, studying habitat selection by birds in the vineyards of southern Switzerland. He also spent over three months as field assistant, studying habitat selection of birds in the highlands of Ethiopia. As a result, Julien has a strong background in bird ecology and evolution.

When back in Switzerland, Julien devotes much of his time to birding the four corners of the country and monitoring birdlife for the Swiss Ornithological Institute. He is very active at finding vagrants and has become a specialist in bird identification. Julien coordinates rarity-research weekends where dozens of birdwatchers are looking for vagrants in strategic locations across the country. He has also been in charge of the bird ringing station at the Col de Jaman in the Swiss Alps.

Julien's passion for overseas birding travels has taken him to five continents, including prolonged periods in Southeast Asia, New Guinea, Africa, Costa Rica and South America. He has a special interest in Andean birds and its extremely diverse avifauna, an interest that developed from his first travels outside Europe in Ecuador and Peru. As well as birds, Julien also likes spending time outside at night looking for mammals, reptiles, spiders and insects.
