Abstract

Antarctica is free of urbanisation, however, 40 year-round and 32 seasonal Antarctic stations operate there. The effects of such human settlements on Antarctic wildlife are insufficiently studied. The main aim of this study was to determine the organization of the bird population of the Mirny Station. The birds were observed on the coast of the Davis Sea in the Mirny (East Antarctica) from January 8, 2012 to January 7, 2013 and from January 9, 2015 to January 9, 2016. The observations were carried out mainly on the Radio and Komsomolsky nunataks (an area of about 0.5 km). The duration of observations varied from 1 to 8 hours per day. From 1956 to 2016, 13 non-breeding bird species (orders Sphenisciformes, Procellariiformes, Charadriiformes) were recorded in the Mirny. The South polar skuas (Catharacta maccormicki) and Adélie penguins (Pygoscelis adeliae) form the basis of the bird population. South polar skuas are most frequently recorded at the station. Less common are Brown skuas (Catharacta antarctica lonnbergi) and Adélie penguins. Adélie penguins, Wilson's storm petrels (Oceanites oceanicus), South polar and Brown skuas are seasonal residents, the other species are visitors. Adélie penguins, Emperor (Aptenodytes forsteri), Macaroni (Eudyptes chrysolophus) and Chinstrap penguins (Pygoscelis antarctica), Wilson's storm petrels, South polar and Brown skuas interacted with the station environment, using it for comfortable behavior, feeding, molting, shelter from bad weather conditions, and possible breeding. South polar and Brown skuas tend to be attracted to the station, while other Antarctic bird species are indifferent to humans. Birds spend part of the annual cycle at the station or visit it with different frequency, but they cannot meet their ecological needs there all year round. The study improves our understanding of the regularities of the phenomenon of urbanization of the avifauna in the polar regions of the planet Earth.

南极人类住区的海鸟:以米尼站为例

然而，南极洲没有城市化，那里有40个全年和32个季节性的南极站。人类住区对南极野生动物的影响还没有得到充分的研究。本研究的主要目的是确定米尼站鸟类种群的组织结构。2012年1月8日至2013年1月7日和2015年1月9日至2016年1月9日在南极洲东部的戴维斯海海岸观测到这些鸟类。观测主要是在无线电和共青城nunataks(面积约0.5公里)进行的。每天的观测时间从1小时到8小时不等。1956 - 2016年，我省共记录到非繁殖期鸟类13种(蝶形目、伞形目、翼形目)。南极贼鸥(Catharacta maccormicki)和南极企鹅(Pygoscelis adeliae)构成了鸟类种群的基础。南极贼鸥最常在该站被记录。不太常见的是褐贼鸥(Catharacta antarctica lonnbergi)和adsamlie企鹅。阿迪海企鹅、威尔逊风暴海燕、南极贼鸥和布朗贼鸥是季节性的居民，其他物种是游客。ad阴郁企鹅，帝企鹅(Aptenodytes forsteri)， Macaroni (Eudyptes chrysolophus)和帽带企鹅(Pygoscelis antarctica)，威尔逊风暴海燕，南极和布朗贼鸥与站内环境相互作用，利用它舒适的行为，觅食，换毛，躲避恶劣天气条件，并可能繁殖。南极和棕色贼鸥倾向于被吸引到空间站，而其他南极鸟类对人类漠不关心。鸟类在一年的周期中有一部分时间停留在该站或以不同的频率访问该站，但它们不能全年满足在该站的生态需求。该研究提高了我们对地球极地地区鸟类城市化现象规律的认识。
