estimated to include a total of 2369 individuals. Rescued penguins A small population of rescued penguins are kept in a dedicated enclosure on the island (known as the Discovery Centre) for visitors to the island to observe. The enclosure was built by the Department of Environment and Conservation in 1987. As well as being a sanctuary to care for injured wild penguins, it is also the home of 10 resident penguins that have been badly injured, orphaned as chicks or born in captivity, and are thus unlikely to survive in the wild. The enclosure has been designed to reflect the natural sandy, coastal scrub environment of the penguins and includes a saltwater pond with viewing panels to watch the little penguins swim. Penguin feedings are held three times daily by a park ranger.
