Black-billed gull - Larus bulleri
Photographed on the Ashley River, Canterbury, New Zealand.
Endemic to New Zealand. The majority of the population (78%) breeds in Southland. Mostly a freshwater inland river and lake gull but also found out to the coast especially estuaries. Some birds remain at colonies throughout the year, others move from inland breeding sites to the coasts. While still regarded as common, large declines on their populations on traditional stronghold breeding rivers in Southland is a concern and the bird’s conservation status was recently elevated to ‘threatened’.
