Knitted penguin jumpers
This is not a fashion statement!
These knitted penguin jumpers play an important role in saving little penguins affected by oil pollution. A patch of oil the size of a thumb nail can kill a little penguin. Oiled penguins often die from exposure and starvation. Oil separates and mats feathers, allowing water to get in which makes a penguin very cold, heavy and less able to successfully hunt for food.
When oiled penguins are admitted to the Wildlife Clinic at Phillip Island Nature Parks, a knitted jumper is placed on the penguins to prevent them from preening and swallowing the toxic oil before they are washed and the oil removed by staff.
453 little penguins were affected by the last major oil spill near Phillip Island in 2001. 96% were successfully saved and rehabilitated at the Wildlife Clinic and released back into the wild.
