Online volunteers are being asked to classify images of penguin families to help scientists monitor the health of penguin colonies in Antarctica. Recent evidence suggests that populations of many species of penguin, such as chinstrap and Adélie, are declining fast as shrinking sea ice threatens the krill they feed on. By tagging the adults, chicks, and eggs in remote camera images Penguin Watch volunteers will help scientists to gather information about penguin behavior and breeding success, as well as teaching a computer how to count and identify individuals of different species.
