    Diving behaviour of Chinstrap penguins (Pygoscelis antarctica) was recorded continuously by time-depth recorders from two adults breeding chicks. Their diving behaviour could be split into bouts by using log frequency method. Organization of dive bouts does not differ within each individuals among days on which dives are recorded but differed between individuals, suggesting that ecological and physiological restrictions differed between the two individuals.
