This note reports observations of two moulting emperor penguins (Aptenodytes forsteri) on Horseshoe Island, West Antarctica, during the Seventh Turkish Antarctic Expedition in February 2023. This is the first time this species has been documented on this island. Emperor penguins largely depend on fast-ice to breed and moult. The Antarctic Peninsula hosts few emperor penguin colonies. Horseshoe Island has become one of the northernmost points along the western Antarctic Peninsula where emperor penguins are documented to moult.

首次在南极洲马蹄岛观察到帝企鹅

 本笔记报告了 2023 年 2 月第七次土耳其南极探险期间在西南极洲马蹄岛观察到的两只换羽帝企鹅 (Aptenodytes forsteri ) 。这是该岛上首次记录该物种。帝企鹅很大程度上依靠固定冰来繁殖和换毛。南极半岛几乎没有帝企鹅栖息地。马蹄岛已成为南极半岛西部最北端的岛屿之一，据记载帝企鹅在此换毛。
