Zookeepers noticed the penguin missing during a routine count on Saturday of the South American birds, the dpa news agency reported yesterday.

After a search of the grounds, zoo personnel were unable to find any signs that the flight-less penguin, which is 50 centimetres tall and weighs 5 kilogrammes, escaped. They concluded it was stolen.
