Cool Facts

• The Mew Gull has an extensive breeding range, with three distinct forms that are sometimes considered different species. The European form, known as the "Common Gull" has less white in the wingtips than the American form, or "Short-billed Gull," and its first-year plumage is much paler. The eastern Asian form known as "Kamchatka Gull" is larger, with a larger bill, and pale yellow eyes.
• Although the Mew Gull is a common bird along the Pacific Coast, it is a rarity in the East. Birds that appear along the Atlantic Coast are likely to be from Europe.
• The Mew Gull is the only "white-headed" gull that regularly uses trees for nesting.
• The European form of the Mew Gull, the "Common Gull," closely resembles the American form in adult plumage, but the two forms differ more in juvenile and first winter plumages. The American form is all dirty gray, with a mostly dark brown tail and dusky wings. The European form is much more black and white, with a paler head and underparts, a white rump and upper tail, a black band on the tip of the tail, blackish wingtips, and a dark line along the back of the wing (the secondaries).
