The function of feeding chases in the chinstrap penguin, Pygoscelis antarctica
Crèching chinstrap penguin chicks chase their parents on the run before being fed. This characteristic behaviour of Pygoscelid penguins has been interpreted in several ways. In an observational study of several colonies in a rookery on Deception Island, South Shetlands, the frequency and duration of...
