Breeding success of known-age black-browed albatrosses (Thalassarche melanophris) at Bird Island, South Georgia, 1977 to 2024
GB/NERC/BAS/PDC/02171
Abstract:
This dataset contains breeding success data from known-age black-browed albatrosses (Thalassarche melanophris) fledged since austral summer 1977 at Bird Island, South Georgia. This dataset includes 2648 breeding attempts from 360 individuals at Bird Island between 1987 and 2024. Data on individual age is also included.
This work was funded as part of the Bird Island Long-term Monitoring Programme at BAS.

| Quality: | Individuals breeding for the first time after the age of 20 years old were removed from the dataset, as they likely reflect ring-reading errors or chronic nonbreeders. This threshold led to the exclusion of 27 birds. | |
| Lineage/Methodology: | Annual monitoring of black-browed albatrosses at Bird Island began in (sub) colony H from austral summer 1975/76, (sub) colony J from austral summer 1995/96 and (sub) colony N from austral summer 2007/08, and continues to date. The data presented here are range until 2024. All breeding adults are ringed with a metal ring (stainless-steel or alloy) and a coloured plastic ring with a unique alphanumeric code. All breeding adults and non-breeders are identified on daily rounds in the early season, and all chicks ringed each year. Nests are visited at daily to weekly intervals, depending on the stage, to record breeding outcome (chick fledged or nest failed). See Froy et al. (2017) J Anim Ecol. 86:1022-1032 and Pardo et al. (2017) PNAS 114: E10829-E10837 for further details. Breeding success is recorded as follows; 0: failed breeding attempt, 1: successfully fledged chick | |
