Joshua Bergmark
Josh lives in Australia with his partner Shahaf and daughter Aya. Working as a professional bird tour leader since he was 16 and travelling extensively throughout Australasia, Eurasia and Africa, his particular passion is for New Guinea and the Pacific where he guided extensively over the last decade in search of many poorly-known endemics before founding Ornis Birding Expeditions.
Julien Mazenauer
Julien started birding when he was 10 and quickly expanded his passion all over the Western Palearctic and ultimately the whole world, where he has been leading tours on five continents for the past five years. When at home in western Switzerland, he lives with his partner Hélène and devotes much of his time counting birds high up in the Alps or looking for vagrants!
Daniel López-Velasco
Dani is a life-long, highly enthusiastic and experienced birder who started birding at the early age of 5. He lives in Asturias, Northern Spain, and worked as a professional bird tour leader for over 10 years before founding Ornis Birding Expeditions. His travels have taken him to over 80 countries across the world, with his favourite places being New Guinea, the Neotropics and the oceans.
Donna Belder
Donna is an ecologist and conservation biologist based in Australia. Truly discovering her passion for birding during university led her to undertake a PhD on woodland birds and become a fully-licenced ringer while also working part-time as a tour leader. Donna is very enthusiastic about her Australian list, reaching 700 Australian birds by age 30 and becoming the youngest ever woman to do so!
Eduardo Patrial
Following his university graduation, Eduardo ran bird surveys across Brazil before starting work as bird guide in 2006. He has since covered all regions of his vast home country, now one of the handful of people able to truly produce exceptional tours here. His humor and passion for birding guarantees great fun in the field, while his persistent searches for the rarest species are second-to-none!
Chris Venetz
Chris grew up in Switzerland, taking several lengthy international birding trips during his early teenage days which evolved into a lifelong passion for the birds of the world. While his exploration of avian diversity has taken him to every continent, he has a particular interest in the Neotropics, Africa, Asia, and New Guinea, where he travelled and led tours most extensively.
Daniel Aldana Schumann
Daniel was born and raised in Guatemala City, but has since relocated to the beautiful and biodiverse slopes of Toliman Volcano, where he lives amongst many special endemic birds! He provided logistics and guiding for several tour companies before joining Ornis, and has plenty of experience leading birding trips across Central and South America, with many more on the horizon!
Diego Calderón-Franco
Diego has been leading birding tours for over 20 years across Colombia and Latin America. Along with discovering many new species for his home country while exploring remote areas from the Serranía de Pirre in the Darién and the Baudó Mountains in the Chocó to the Guianan Shield Lowlands, he has also been privileged to take part in the description of several Neotropical birds new to science!
