Franklin's Gull, or Prairie Dove, a gull that spends the summer on the Great Plains from southern Canada to central United States. The bird does much good in this region by eating grasshoppers and other crop-damaging insects. It also eats frogs, fish, and mollusks. It is named for the English explorer Sir John Franklin.
Colonies of Franklin's gulls nest in marshes. The female lays two to four pale-brown eggs. Some of the birds winter on the Gulf Coast, but most fly to the Pacific coast of South America.
The Franklin's gull grows to 15 inches (38 cm) in length. In summer plumage, it has a black head, gray back, gray wings tipped with black and edged with white at the rear, and white, pink-tinged underparts. In winter, its head and underparts turn white.
The Franklin's gull is Leucophaeus pipixcan.
