Tracking ring-billed gulls

Main Project Information
Presented By Université du Québec à Montréal (UQAM)
Goal Determine distribution and movements of ring-billed gulls
Task Search for marked birds and report the sighting via web site
Where Global, anywhere on the planet

More than 10,000 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.

How to Join

Ring-billed gulls have been marked with blue or yellow plastic band with 3 distinct alphanumeric codes plus a US Fish & Wildlife Service steel band. If you can take a picture that shows the color band and send it to us, we will be able to confirm your observation. If you see a marked bird, please report your observation on our web site at We will send you information about where and when the bird was banded and whether it has been observed since its marking.
