Gentoo penguin nesting chronology at Bird Island, South Georgia, from 1988 to 2019 - VERSION 1.0

The chronology of Gentoo penguins on Bird Island, South Georgia has been monitored since 1988 (no data for 1989-90 or 1990-91). 30 nests are marked in the colony at Square Pond, and 40 in the Johnson Beach colony. Regular checks are made to record when eggs are laid and the peak laying date (when 75% of nests have eggs) is calculated.

**** PLEASE BE ADVISED TO USE VERSION 2.0 DATA *****

The VERSION 2.0 data set (see 'Related Data Set Metadata' link below) has been extended with five additional years of data. No changes have been made to the data included in VERSION 1.0.

自1988年起，研究人员便对南乔治亚伯德岛（Bird Island）上的巴布亚企鹅（Gentoo penguin）的产卵时序开展监测工作，期间1989-1990年及1990-1991年无有效观测数据。该种群在斯夸尔池塘（Square Pond）聚居区标记了30个企鹅巢，在约翰逊海滩（Johnson Beach）聚居区则标记了40个企鹅巢。研究人员定期开展巡查以记录产卵时间，并计算得到产卵高峰期——即75%的企鹅巢均已完成产卵的时间节点。本项研究由英国自然环境研究委员会（Natural Environment Research Council, UK）向英国南极调查局（British Antarctic Survey）提供的核心科研经费资助。
