Life Span The life span of the Lesser Black-backed Gull can vary based on environmental factors, predation, and human impacts. Here are some general points about their life span: Average Life Span: Lesser Black-backed Gulls typically live for about 12-15 years in the wild. However, some individuals can live significantly longer. Longevity Records: The oldest known Lesser Black-backed Gull was recorded to be over 34 years old, based on ringing (banding) data. Factors Influencing Life Span: Predation: Eggs and chicks are vulnerable to predation by other birds and mammals. Human Activities: Pollution, habitat destruction, and disturbances can affect their survival. Food Availability: Access to food sources significantly impacts their longevity and reproductive success. Habitat and Distribution Breeding: Lesser Black-backed Gulls breed in coastal and inland regions, often on cliffs, islands, and rooftops. They prefer locations that provide safety from predators and proximity to feeding areas. Wintering: During the non-breeding season, they migrate to southern Europe, Africa, and the Middle East.
