emperor penguin baby cear

Chicks require attentive parents for survival. Both parents feed the chick regurgitated food. Adults recognize and feed only their own chick. Parents are able to identify their chick by its distinctive call.
During fieldwork at the Falkland Islands, a researcher observed a behavior never witnessed before—an older gentoo chick was recorded several times regurgitating food and feeding its younger sibling. It is not understood why the older chick would feed its younger sibling, as in theory such an action would likely reduce the older chick's chances of survival.
Male emperor penguins exhibit a feature unique among penguins. If the chick hatches before the female returns, the male, despite his fasting, is able to produce and secrete a curdlike substance from his esophagus to feed the chick, allowing for survival and growth for up to two weeks.
Parents brood chicks (keep them warm) by covering them with their brood patch.
