Seabird populations in Antarctica serve as indicators to assess the impacts of global environmental change. Ecological data on seabirds in Antarctica are scarce due to limited knowledge on their distribution and abundance in most parts of the continent. In this study, we investigated the status of seabird species around the Indian research stations Bharati at Larsemann Hills, Prydz bay and Maitri at Schirmacher Oasis, central Dronning Maud Land located in east Antarctica. We conducted primary surveys during austral summers under the Indian Antarctic Program and compiled published as well as unpublished information on seabird distribution from these areas. We employed intensive area search methods to locate presence of seabird nesting and moulting sites. Ten species were recorded from Larsemann Hills with confirmed breeding of snow petrel, south polar skua and Wilson’s storm-petrel. Only south polar skua and Adélie penguin were reported breeding at Schirmacher Oasis with unconfirmed breeding of Wilson’s storm-petrel. This study presents the first detailed synthesis of status of seabirds from Larsemann Hills and Schirmacher Oasis regions in Antarctica and serves as a strong baseline for future ecological work on seabirds in the sector of operation of Indian Antarctic Program.

南极洲东部拉瑟曼山和席尔马赫绿洲的海鸟过去记录和当前分布

南极洲的海鸟种群可作为评估全球环境变化影响的指标。由于对南极大陆大部分地区的分布和丰富度的了解有限，有关南极洲海鸟的生态数据很少。在这项研究中，我们调查了印度研究站周围的海鸟物种状况巴拉蒂在 Larsemann Hills、Prydz 湾和迈特里在位于南极洲东部的 Dronning Maud Land 中部的 Schirmacher Oasis。我们在印度南极计划下的南方夏季进行了初步调查，并汇编了有关这些地区海鸟分布的已发表和未发表的信息。我们采用密集的区域搜索方法来定位海鸟筑巢和换羽地点的存在。Larsemann Hills 记录了 10 个物种，确认繁殖了雪燕、南极贼鸥和威尔逊风暴海燕。据报道，只有南极贼鸥和阿德利企鹅在 Schirmacher 绿洲繁殖，威尔逊风暴海燕的繁殖未经证实。
