The Common Gull (Larus canus), also known as the Mew Gull in North America, is a medium-sized gull native to the cool temperate regions of the Palearctic, spanning from Iceland and Scotland to eastern Russia. Despite its name, it is often scarcer than other species like the herring or black-headed gull in many regions.

Conservation Status:
In the UK, the Common Gull is currently on the Red List of Birds of Conservation Concern as of 2026, indicating a significant decline in its breeding population.
Key Characteristics:
- Appearance: Adults have a silvery-grey back, white underparts, and black wingtips with large white spots known as "mirrors". They are often described as looking like a smaller, "gentler" version of the Herring Gull.
- Identification Features:
- Bill: Thin and yellow-green, lacking the red spot found on larger gulls.
- Eyes: Typically dark, which contributes to its softer expression.
- Legs: Greenish-yellow or pale yellow-green.
- Winter Changes: In winter, the head develops greyish-brown streaks or mottling, and the bill may show a dark band near the tip.
Habitat and Distribution:
- Breeding: They nest colonially or solitarily on coastal marshes, moorlands, rocky ledges, and occasionally on buildings. In the UK, they primarily breed in Scotland and northern England.
- Wintering: During winter, they migrate to more southern latitudes, including the Mediterranean and parts of Asia. They are frequently seen on farmland, sports fields, and at landfill sites during this time.
Behavior and Diet:
- Diet: As omnivores, they consume a variety of food including fish, invertebrates, small prey, and scavenged human waste.
- "Paddling": They are known for a behavior called "paddling," where they stamp their feet on the ground to imitate rain, tricking earthworms and other invertebrates into rising to the surface.
Conservation Status:
In the UK, the Common Gull is currently on the Red List of Birds of Conservation Concern as of 2026, indicating a significant decline in its breeding population.
