| Larus pipixcan |
The Franklin's Gull, Larus pipixcan is a small gull. It breed in central provinces of Canada and adjacent states of the northern USA. It is [[[bird migration|migratory]], wintering in the Caribbean, Peru and Chile. Although it is uncommon on the coasts of [North America]], it nevertheless occurs as a rare vagrant to western Europe.
This species is easy to identify. The summer adult's body is white and its back and wings are much darker grey than all other gulls of similar size except the larger Laughing Gull. The wings have black tips with an adjacent white band. The bill and legs are red. The black hood of the breeding adult is mostly lost in winter.
Young birds are similar to the adult but have less developed hoods and lack the white wing band. They take three years to reach maturity.
Franklin's Gulls breed in colonies near prairie lakes. The nest is constructed on the ground, or sometimes floating. The 2 or 3 eggs are incubated for about three weeks.
These are omnivores like most Larus gulls, and they will scavenge as well as seeking suitable small prey.
