McGill Bird Observatory monitors winter bird populations during the 21 weeks between fall and spring migration seasons. Volunteers maintain feeders on-site to track species that either reside year-round or migrate south for the winter. This helps us better understand migration routes, timing, and habitat preferences.
While relatively few species overwinter at MBO, some are rarely seen during other seasons, making winter the best time to study them. Early and late winter observations also help document lingering fall migrants and early spring arrivals. Few bird observatories at this latitude operate year-round, giving us a unique opportunity to contribute valuable data on winter bird distribution.
Results
Birds are captured using three mist nets placed around a cluster of feeders. An audio lure playing calls of common winter species is also used to attract birds.
Winter monitoring is more sporadic, as weather conditions often limit banding opportunities.
Banding total in 2022-2023: 122 birds of 14 species
Banding total since 2005 : 5666 birds of 137 species

How you can help
Our research is made possible through the generous support of donors, volunteers, and partners. Your donations help keep the observatory running, allowing us to conduct vital studies on bird migration, stopover behaviors, and habitat conservation. Contributions directly fund research equipment, banding efforts, and outreach initiatives.
You can also support our work by volunteering, participating in community science projects, or simply spreading awareness about the importance of bird conservation. Every effort makes a difference in protecting migratory species and their habitats
