Come breeding time, the mother bird still incubates her eggs and keeps her fledglings warm, but the feeding is not left entirely to the male bird. He is helped by other adults who take it in turns to feed the young and bring food for the mother.
繁殖期間，孵卵及幼雛保溫工作仍由產卵的母鳥負責，但出外覓食卻不是「父親」的專利，而由公鳥和其他成鳥分工合作，輪流餵食幼鳥和帶食物給母鳥補充體力。
