Mediterranean Gull vs Common Gull

In short

The Mediterranean Gull and Common Gull can be distinguished by key structural and plumage differences. The Mediterranean Gull has a thicker, more robust bill and a distinctive all-white wingtip in adults, while the Common Gull has a slimmer bill and black markings on the wingtips. Both species share similar habitats but differ in vocalizations.

Identification tips

1. Bill Shape: Look for the Mediterranean Gull's thicker, more robust bill. 2. Wingtip Color: Check for the Mediterranean Gull's all-white wingtips in adults. 3. Head Pattern: In breeding season, the Mediterranean Gull has a full black hood, unlike the Common Gull. 4. Size and Structure: Note the Mediterranean Gull's slightly larger size and bulkier build. 5. Vocalizations: Listen for the Mediterranean Gull's nasal calls compared to the Common Gull's varied calls.

Size

Plumage

Mediterranean Gulls in adult plumage have a striking all-white wingtip and a black hood in breeding season, while Common Gulls have black markings on the wingtips and lack a full black hood, showing only a streaked head in non-breeding plumage.

Behaviour

Both species exhibit similar gull-like behaviors, including foraging in flocks and scavenging, but specific behavioral differences are not well-documented.

Habitat

Both species are found in coastal and inland water bodies, but the Mediterranean Gull is more restricted to southern Europe and coastal areas, whereas the Common Gull is widespread across Europe and Asia.

Voice

The Mediterranean Gull has a more nasal and monotonous call compared to the Common Gull's more varied and higher-pitched calls.
