Abstrakt: A recent survey conducted in Cumberland Bay, South Georgia, has found that humpback whales have returned to the area after a century of whaling. The survey estimated that approximately 12,103 humpback whales were using South Georgia waters in the 2018/2019 season, representing a significant increase in abundance. Changes in oceanographic conditions and the distribution of their primary food source, Antarctic krill, may have influenced the whales' habitat preferences. The survey also observed mother-calf pairs and larger groups of whales outside the bay, suggesting limited feeding opportunities farther inside. The study provides a summary of the presence of humpback whales in Cumberland Bay, South Georgia, and discusses the potential impact of their return on the local marine ecosystem.
