海鸟丰度和繁殖分布有潜力作为生态指标。南极半岛西部是过去50年来世界上局部气温上升幅度最大的三个地点之一。本研究的目的是监测 2010/11 繁殖季期间南极半岛西北部丹科海岸北部地区海鸟繁殖种群的分布和丰度。这些鸟类包括威尔逊风暴海燕 (Oceanites oceanicus)、南极贼鸥 (Stercorarius maccormicki)、海带鸥 (Larus dominicanus)、南极燕鸥 (Sterna vittata)、雪鞘嘴鸟 (Chionis alba)、帽带企鹅 (Pygoscelis antarctica)、南方巨海燕 (Macronectes giganteus)、巴布亚企鹅企鹅 (Pygoscelis papua)、海角海燕 (Daption capense) 和南极鸬鹚 (Phalacrocorax bransfieldensis)。尾鹬、南方巨海燕和鞘嘴鸟的年繁殖种群数量增长有所增加，其余物种的繁殖种群数量趋势稳定。鉴于海鸟种群可以提供有关其进食和筑巢环境条件的宝贵信息，这项研究强调了维持基础监测研究的必要性。
Seabird abundances and breeding distribution have the potential to serve as ecological indicators. The western Antarctic Peninsula is one of the three sites in the world with the greatest increases in local temperature during the last 50 years. The aim of this study was to monitor the distribution and abundance of breeding populations of seabirds in the northern sector of the Danco Coast, north-west of the Antarctic Peninsula, during the breeding season 2010/11. The birds were the Wilson's storm petrel (Oceanites oceanicus), South Polar skua (Stercorarius maccormicki), kelp gull (Larus dominicanus), Antarctic tern (Sterna vittata), snowy sheathbill (Chionis alba), chinstrap penguin (Pygoscelis antarctica), southern giant petrel (Macronectes giganteus), gentoo penguin (Pygoscelis papua), Cape petrel (Daption capense) and Antarctic shag (Phalacrocorax bransfieldensis). Annual breeding population growth increased in pygoscelids, southern giant petrel and sheathbill, and for the remaining species, breeding population trends were stable. Given that seabird populations can provide valuable information on the conditions of their feeding and nesting environments, this study highlights the need to maintain basics monitoring studies.
