Dr. Jean François Therrien • Reverse Migration at Tadoussac • Nov 2025

The Tadoussac Bird Observatory is located on a major migratory flyway in eastern North America. It witnesses annually hundreds of thousand raptors, songbirds and waterfowl transiting through the site from their breeding grounds across the boreal forest and arctic tundra to wintering grounds across the Americas and back. Beside spectacular Autumn flights, the site is also known for the spectacular Spring reverse migration events where a literal “River of Warblers” make migratory correction movements en route to their boreal breeding grounds. The presentation will provide an overview of research and monitoring activities going on at the Tadoussac Bird Observatory with a focus on the extraordinary migration events happening at the site. Jean-François “JF” Therrien grew up in Sherbrooke, Canada, about 30 minutes from the border with Vermont. He received a bachelor’s degree in biology from the Université de Sherbrooke and earned both a master’s degree and a Ph.D. from the Université Laval. In 2011 he was appointed Senior Scientist at Hawk Mountain Sanctuary where he leads the Sanctuary’s research projects in the Arctic and is involved in several studies including the movement ecology of New World vultures and peregrine falcons across the Americas. In 2022 he was appointed Scientific Director at the Tadoussac Bird Observatory. The mission of the Tadoussac Bird Observatory is to monitor migratory bird populations, specifically boreal species, in order to assess their demographic trends, and to train ornithologists and raise public awareness on migration, boreal forest ecology, and the bird species inhibiting such habitats.
