Effects of food variability on growth rates, fledging sizes and reproductive success in the Yellow‐eyed Penguin Megadyptes antipodes

Effects of a change of diet on growth rates and fledging sizes of Yellow‐eyed Penguins Megadyptes antipodes were examined at two breeding areas on South Island, New Zealand, during two breeding seasons. An adverse change in diet was observed in the second season. Evidence for this included depressed growth rates of weight, differential growth of weight and most morphometric parameters between one‐ and two‐chick nests in the second season, lower...
