Breeding success of Gentoo penguins at Bird Island, South Georgia, from 1981 to 2025 - VERSION 2.0

The breeding success (calculated from nest and chick counts) of Gentoo penguins is monitored annually at Bird Island, South Georgia. The number of incubating nests and chicks reaching fledging stage are counted in several Gentoo penguin colonies. Data exist from 1981 onwards.

This dataset is an updated version of Trathan, P., Waluda, C., & Ratcliffe, N. (2021). Breeding success of Gentoo penguins at Bird Island, South Georgia, from 1982 to 2020 - VESION 1.0 (Version 1.0) [Data set]. NERC EDS UK Polar Data Centre. https://doi.org/10.5285/c8d5a7a4-e19b-497f-b7ae-56f9a2b15a56. The update consists of five additional years of data. No changes have been made to the data included in the previous dataset.

巴布亚企鹅（Gentoo penguin）的育雏成功率（通过巢群数量与雏鸟计数计算得出）在南乔治亚岛伯德岛开展年度监测。研究人员在多个巴布亚企鹅群落中，统计正在孵卵的巢数以及成功达到出飞阶段的雏鸟数量。该数据集的观测数据自1981年起收录。

本数据集为Trathan P、Waluda C与Ratcliffe N（2021）发布的《1982-2020年南乔治亚岛伯德岛巴布亚企鹅育雏成功率》版本1.0（Version 1.0）[数据集]的更新版本，原始数据集存储于英国自然环境研究委员会（NERC）环境数据服务中心（EDS）英国极地数据中心，DOI：10.5285/c8d5a7a4-e19b-497f-b7ae-56f9a2b15a56。本次更新新增了5年的观测数据，未对原数据集收录的内容作出任何修改。
