Eudyptula minor
Penguin Island is a 12.5 ha (31 acres) island off the coast near Perth. It is home to a colony of approximately 1200 little penguins, the largest population of the birds in Western Australia. The waters surrounding the island make up the Shoalwater Islands Marine Park. The little penguin population which breeds on Penguin Island is genetically distinct and in decline. In 2007 there were between 1600 and 2000 little penguins on Penguin Island during breeding months. By 2011, the number had dropped to about 1000. Penguins have been observed taking longer foraging trips leading to chick malnutrition and starvation. Prey depletion and climate change are considered to be major pressures on the breeding population. A proposal to construct a marina at Point Peron is also considered a future threat.
A number of rescued penguins are kept in a dedicated enclosure for visitors to the island to observe. A small population of rescued penguins are kept in a dedicated enclosure on the island (known as the Discovery Centre) which 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 the 10 resident penguins that have been badly injured, orphaned as chicks or born in captivity, and it is unlikely that they would survive in the wild. It has been designed to reflect the penguins natural sandy, coastal scrub environment 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.
In the 21st century, spotting wild little penguins at the island is unusual as for most of the year, daylight hours are spent at sea chasing fish, and visitors are strictly prohibited from being on the island except during specified daylight hours from mid-September to early June.
