Snares Crested Penguin 03.tif

Download
Snares crested penguins take to the sea to forage for food. Highly productive conditions around the Snares Islands make them an ideal place to raise their young. Stable isotope studies of living and historical specimens show that ocean productivity and the diet of the penguins here have remained unchanged for 120 years. This is in stark contrast to Campbell Island, where a change in ocean productivity appears to be responsible for a massive decline in rockhopper penguins. The Snares’ environmental stability and pest-free status make them invaluable as a scientific control for penguin studies around the world.
