ID and Whereabouts

To accurately identify the Ring-billed Gull, close observation is necessary. As its name suggests, this species is distinguished by a prominent black ring around its bill, a feature also visible in older juveniles. Although it is the smallest gull found in Montreal, size alone is not a reliable identifier, particularly when compared to the slightly larger Herring Gull.

The Ring-billed Gull can be observed year-round along the rivers and lakes of Montreal. It is particularly abundant at the river's edge in parks such as Rapids Park Lachine. Although sightings are less frequent in winter, the species can still be found within the city itself. Typically, when you encounter a gull on the streets of Montreal, it is likely a Ring-billed Gull.
