When we do our rounds there is usually one parent at each Yellow-eyed penguin nest guarding the chicks. Every once in a while we come across the whole family with one parent having just returned from feeding. The chicks are usually quite active as they are excited about dinner. Here the parents are singing to each other. This reunion of the whole family only lasts maybe 20 minutes then the parent who has been at home will depart to get the next load of fish for the chicks. The other parents stays home and looks after the now full and sleepy chicks. Very domestic!!
