The site: De Hoop Nature Reserve
The De Hoop Nature Reserve is about 250 km east of Cape Town. It is one of the largest natural areas managed by CapeNature and the associated Marine Protected Area is one of the largest coastal MPAs in South Africa. African Penguins naturally attempted to establish a colony on the eastern edge of the reserve in 2003. The colony grew to more than 20 pairs in 2006, with about 100 non-breeding penguins roosting there, before predation by terrestrial predators (likely caracal) caused the penguins to abandon the attempt. BirdLife South Africa, with the support of CapeNature and the Southern African Foundation for the Conservation of Coastal Birds (SANCCOB), aims to re-establish the colony and protect it from predators.
Phase 1: Predator protection and social attraction
After a lengthy process of ensuring the correct management plan was in place, work started on site in October 2018. A predator-proof fence was constructed to prevent access by predators such as leopard, caracal, mongoose, genet and baboons.
To get penguins to adopt the site, we are engaging in a little trickery. Because penguins breed in colonies they are less likely to adopt a new site with no penguins already breeding there. To make it look and sound like an existing colony we have put in place life-like penguin decoys and speakers playing penguin calls. These measures aim to attract young penguins prospecting for breeding sites. Penguins are regularly seen in the waters around De Hoop so it is hoped that the lure of a new breeding site in an area with abundant food will be successful.
Phase 2: Penguin translocation
The second phase of the project is to release juvenile penguins at the site. The released penguins are hand-reared at SANCCOB; most hatched from abandoned eggs or chicks rescued from other penguin colonies and reared at the organisation’s Cape Town facility. We need to release fledglings as they have not yet chosen a place to breed. Once an African penguin starts breeding at a colony, they return there year after year. By releasing fledglings, we hoped that they will return to De Hoop Nature Reserve to breed when they are ready to do so in three to six years.
We plan to continue releasing at least 60 young penguins per year until at least 2026, as work on other seabird colony establishment projects has shown that releasing large numbers gives the greatest chance of success.
