The Silver Gull is the most common and smallest gull in Australia (40-45 cm) and can be found just about anywhere where there is water. They are closely related to the Red-billed Gull of New Zealand and were considered to be the same species until recently. The first four photos are of adults, the next two are second-year birds and the last is a 1st-winter bird. As the gulls get older, the eye-ring, beak and legs become more red.
