Tracking Ring-billed gulls

Year-round tracking of Ring-billed gull movement in eastern North America.

Tracking Ring-billed gulls

More than 7,000 ring-billed gulls have been marked near Montreal, Quebec with individually coded bands to track their movements throughout their annual cycle. We are more specifically interested by their post-breeding dispersal and their fidelity to their colony. Repeated observations of individuals also allow us to estimate annual survival. This is part of a larger study that aimed at understanding the behavior and population dynamics of these birds within an integrated management framework. More information about the project can be found on our website:
