For the first time, an Antarctic blue whale has been successfully matched across years in South Georgia—thanks to citizen scientists and the power of photo-identification shared through HappyWhale. This remarkable individual was first recorded in 2019 and re-sighted in 2026 during an ORCA survey conducted aboard HX’s Fram.
These sightings and images are making a vital contribution to the Sustained Monitoring of Whales in South Georgia project, strengthening long-term insights into whale presence and movement in this region.
Although confirmed Antarctic blue whale photo records here remain limited, the match provides exciting evidence of possible regional fidelity—suggesting South Georgia may host a local population rather than only transient visitors from the wider circumpolar group. This match is only made with the support of all the project partners and funding from Darwin Plus, South Georgia Heritage Trust and Friends of South Georgia Island.
This discovery highlights the growing impact of collaborative research and citizen science in revealing the hidden patterns of Earth’s largest animals.
