Parent–offspring conflict and transition to crèche phase in Chinstrap Penguins (Pygoscelis antarctica)
Abstract Parent–offspring conflict theory predicts that offspring seek to prolong the parental care period, while parents strive to shorten it as much as possible. Transition to the crèche phase in penguins involves changes in the dynamic of parental investment in chicks, and thus may be modulated b...

Abstract Parent–offspring conflict theory predicts that offspring seek to prolong the parental care period, while parents strive to shorten it as much as possible.
