Description
It breeds in central provinces of Canada and adjacent states of the northern United States. It is a migratory bird, wintering in Argentina, the Caribbean, Chile, and Peru. 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. Measurements: Length: 12.6-14.2 in (32-36 cm) Weight: 8.1-10.6 oz (230-300 g) Wingspan: 33.5-37.4 in (85-95 cm) Although the bird is uncommon on the coasts of North America, it occurs as a rare vagrant to northwest Europe, south and west Africa, Australia and Japan, with a single record from Eilat, Israel, in 2011 (Smith 2011), and a single record from Larnaca, Cyprus, July 2006. At the beginning of 2017 has been observed also in Southern Romania, southeast Europe.

Feeding Habits
Franklin's Gull primarily feed on invertebrates, especially insects, during breeding. They actively forage over wetlands and farmlands, often following tractors. Their diet includes beetles, grasshoppers, locusts, and earthworms, also consuming small fish and crustaceans by shorelines in winter, and occasionally scavenging at dumps.
Habitat
Franklin's Gull predominantly resides in freshwater marshes with dense emergent vegetation during breeding season, forming tightly-packed colonies. These birds are highly adaptable, extending their post-nesting range to prairies and various wetlands, as well as following agricultural activities for feeding. During migration, franklin's Gull demonstrates extraordinary adaptability, with sightings across diverse North American landscapes and altitudes exceeding 14,000 feet. In winter, franklin's Gull favors coastal areas and oceans up to 30 miles offshore, though some populations exploit the high-altitude lakes in Peru, showcasing a broad ecological tolerance.
Nest Behavior
Franklin's Gull engages in cooperative nest building. Both sexes contribute to the construction process that continues throughout incubation, due to the decay and sinking of the nest's material. Nest building coincides with the breeding season, with parents diligently adding vegetation to maintain the nest.
Nest Characteristics
Franklin's Gull constructs nests in shallow water amidst floating or anchored vegetation, often near emergent plants. The nest is a platform of wet vegetation, likely pilfered from other nests, with a central depression. Initial construction is approximately 17 inches in diameter, expanding up to 40 inches. A notable feature is a small ramp on one side.

Behavior
Franklin's Gull displays a rich tapestry of social and breeding behaviors. Typical days are spent feeding, often in groups, and engaging in intricate courtship rituals that include vocal displays and mutual feather erecting accompanied by alternate movements to express interest. During nesting, both sexes share the construction of floating vegetation nests, incubation, and vigilant defense against predators, though they maintain a peaceful coexistence with neighboring birds. Post-hatching, franklin's Gull's parental involvement is steadfast, with both providing food and protection until fledging. Migration and wintering periods see franklin's Gull forming congenial, mixed-species flocks, showing their gregarious nature while remaining wary of disturbances, leading to silent 'panic flights' when threatened.
