Abstract:
This dataset captures annual measurements of body mass for Adelie penguin chicks at Signy Island, from 1997 until 2020. Between 50 and 100 chicks are measured on beaches immediately prior to their departure, with 3-5 weighing sessions carried out annually per species in the period before fledging is complete. This monitoring contributes to the CCAMLR Ecosystem Monitoring Program (CEMP) and is part of the annual seabird Long Term Monitoring Science carried out by the British Antarctic Survey at Signy Island.
This work was funded by Natural Environment Research Council (UK) core funding to the British Antarctic Survey.

| Quality: | Accuracy within 50 g. Sessions are ideally repeated approximately every 5 days or less, depending on the rate of fledging. In some years a total of three sessions can be carried out before fledging is complete. GPS coordinates are of surveyed colonies in this dataset that were measured with GPS devices. |
|
| Lineage: | Body mass of Adelie penguin fledglings is measured annually on Signy Island following CCAMLR CEMP Standard Method A7A. Weighing takes place in January and begins when the total number of chicks in monitored creches begin to fall and chicks are observed gathering on beaches prior to departure to sea. A specially designed net is used to safely capture each bird before carefully placing it into a weighing bag. Each fledgling is then measured to the nearest 50 g using a spring balance and subsequently gently removed from the bag before being marked with non-permanent stock marker on their chest to avoid recapture. This process is repeated for approximately 50-100 chicks in each colony, usually over a minimum of 3 sessions, or every 5 days until fledgling is complete. | |
