White Tern Feeding

For the first several days tending a newly hatched chick is a full-time family effort. At this early age, one adult remains with the chick, brooding it to help it thermal regulate, while the other adult forages offshore. After catching fish of appropriately small size, the adult returns to the nest site and offers them to the chick, doing its best to help the chick take the fish head first. The young hatchling's inexperience and the difference in bill lengths makes grasping the last fish from the adult particularly challenging. It's therefore not unusual for the other adult to take that last fish with the tip of its bill and offer it to the chick. After temporarily satisfying its hunger one of the adults often then preens the chick a bit before it resumes brooding it. The second adult heads back out to sea and the cycle begins again.
