Survival rate of yellow-eyed penguin eggs and chicks on the Otago Peninsula

Egg-and-chick survival frequency in the yellow-eyed penguin was followed for nineteen nests in three breeding areas on the Otago Peninsula. Observations were made through the tenth post-hatching week for each nest. Survival rate was substantially worse than that reported by Richdale in 1957. There were also differences in survival rate among the three breeding areas within the sample. It is suggested that human and farm-animal activity is responsible for the relatively poor survival rates.
