More than 43 000 Cape gannets have gathered on Bird Island this breeding season, marking a significant conservation milestone for one of South Africa’s most important seabird colonies.
The thriving population highlights the success of ongoing conservation work led by CapeNature, alongside partners such as the Department of Forestry, Fisheries and the Environment. The island has seen a notable increase in numbers, climbing from consistent counts in the 30 000s over recent years to well into the 40 000s in 2026.
This growth is especially encouraging given the species’ conservation status. The Cape gannet remains classified as Endangered on the International Union for Conservation of Nature Red List, and Vulnerable locally, making Bird Island a critical refuge for its survival.
The colony’s recovery has not been without setbacks. In 2005, seal predation forced the birds to abandon the island entirely. Through careful intervention, including predator management and the use of decoys to attract returning birds, conservationists were able to successfully restore the colony.
So far this season, more than 7 600 fledglings have been recorded, with several weeks still remaining. Rangers have also ringed hundreds of chicks and adult birds to support long-term research and tracking efforts.
According to Ashley Naidoo, strong gannet numbers are a positive indicator of ocean health along the West Coast. Healthy seabird populations depend on stable marine ecosystems, making their presence a key signal of environmental balance.
Bird Island is also home to a rich variety of seabirds, including cormorants, terns and gulls, while even a moulting penguin has briefly joined the colony this season.
With improved visitor facilities and updated educational signage, Bird Island continues to attract birdwatchers and nature enthusiasts eager to witness one of the country’s most remarkable wildlife spectacles.
