Herring gulls, Twillingate, Newfoundland,June 2, 2918,
Larus argentatus
The Herring Gull has extended its breeding range southward along the Atlantic Coast, and may be displacing the more southern Laughing Gull from some areas. At the northern end of its range, however, the Herring Gull is itself being displaced by increasing numbers of the Great Black-backed Gull.
