Abstract

A juvenile king penguin (Aptenodytes patagonicus) was sighted at San Martín Station, Marguerite Bay, west of the Antarctic Peninsula (68°07'S, 67°08'W) on 3 February 2020. The animal was apparently healthy. It was uninjured, moving freely between the station buildings. It remained in the area until 27 March, when it was last seen. Numerous king penguin records have been reported in recent years, mostly in the South Shetland Islands. Two chicks have even been recorded hatching on these islands, but there is currently no evidence that king penguins have raised a chick to emancipation successfully. Here we present the most southerly known record of king penguins, the only one farther south than the Antarctic Circle. Coupled with observations from other parts of Antarctica, the information presented here supports previous suggestions by other authors of a southwards expansion of this species specifically in the Antarctic Peninsula region. The presence of this species at numerous Antarctic localities suggests that the known distribution of this penguin could change in the near future in response to climate change.

探险家国王：南极半岛国王企鹅（Aptenodytes patagonicus）的南方报告

2020 年 2 月 3 日，在南极半岛西部玛格丽特湾的圣马丁站（南纬 68°07'，西经 67°08'）发现了一只幼年国王企鹅（Aptenodytes patagonicus）。这只动物显然很健康。它没有受伤，在站内建筑物之间自由移动。它一直停留在该地区，直到 3 月 27 日最后一次被人看到。近年来，有许多国王企鹅的记录，主要是在南设得兰群岛。甚至有两只雏企鹅在这些岛屿上孵化的记录，但目前还没有证据表明国王企鹅成功地将一只雏企鹅养大到出壳。在这里，我们展示了已知最南端的国王企鹅记录，也是南极圈以南唯一的记录。结合南极洲其他地区的观察结果，这里提供的信息支持了其他作者之前提出的该物种向南扩展的建议，特别是在南极半岛地区。该物种在南极众多地点的出现表明，在不久的将来，这种企鹅的已知分布可能会随着气候变化而改变。

期刊介绍： Antarctic Science provides a truly international forum for the broad spread of studies that increasingly characterise scientific research in the Antarctic. Whilst emphasising interdisciplinary work, the journal publishes papers from environmental management to biodiversity, from volcanoes to icebergs, and from oceanography to the upper atmosphere. No other journal covers such a wide range of Antarctic scientific studies. The journal attracts papers from all countries currently undertaking Antarctic research. It publishes both review and data papers with no limits on length, two-page short notes on technical developments and recent discoveries, and book reviews. These, together with an editorial discussing broader aspects of science, provide a rich and varied mixture of items to interest researchers in all areas of science. There are no page charges, or charges for colour, to authors publishing in the Journal. One issue each year is normally devoted to a specific theme or papers from a major meeting.
