Fledging weights of macaroni penguin chicks from a colony at Fairy Point, Bird Island, from 1989 to 2025 - VERSION 2.0
GB/NERC/BAS/PDC/02148
Abstract:
The weights of fledging macaroni penguin chicks at Bird Island have been monitored since 1989. The colony at Fairy Point, also known as Little Mac, contains approximately 400 breeding pairs. Each year, just before their departure from the colony, a sample of 100 fledgling birds are weighed as part of the Bird Island long-term monitoring programme. This data is submitted to the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) as part of their Ecosystem Monitoring Programme (CEMP).

| Lineage/Methodology: | 100 Macaroni penguin chicks at Fairy Point (Little Mac) are caught and weighed on the 18th February each year. All chicks are weighed using a 10kg Pesola and bag. Care is taken to ensure no individual is weighed more than once. All sampling procedures used are regulated by the British Antarctic Survey Ethical Review Committee in collaboration with Cambridge University and the UK Home Office. This dataset has been updated to add five additional years of weights. The metadata has been updated accordingly. All data were collected under permit from the Government of South Georgia and the South Sandwich Islands. All sampling procedures used were regulated by the British Antarctic Survey Ethical Review Committee in collaboration with Cambridge University and the UK Home Office. |
