Fledging weights of Gentoo penguin chicks from a colony at Johnson Cove, Bird Island, from 1989 to 2020 - VERSION 1.0

The weights of fledging Gentoo penguin chicks at Bird Island have been monitored since 1989. The colony at Johnson Cove can have over 1000 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).
