Great Black-backed Gull (Larus marinus)

The Great Black-backed Gull (Larus marinus) is the largest gull species found in Montreal, known for its imposing size and striking appearance. Often seen alone at local parks, this majestic bird is easily identifiable by its dark grey back and distinctive red spot on its yellow beak.

Identification and Whereabouts

The Great Black-backed Gull is distinguished by its dark grey back and the prominent red spot on its yellow beak. It is notably larger than the more common Ring-billed Gull, which features a light grey back and a distinctive black ring around its beak.

The Great Black-backed Gull can be observed throughout the year, with the exception of winter. It is often found perched on rocks surrounded by water. Notably, this species is rarely seen mingling with flocks of other gulls.
