Habitat use and diving behaviour of macaroni Eudyptes chrysolophus and eastern rockhopper E. chrysocome filholi penguins during the critical pre-moult period
International audience After the breeding season, penguins mustreplenish body condition and accumulate sufficient energystores before their annual moult ashore; failure to do somay lead to starvation.
