It is a real treat to have the opportunity to study these birds. To reach their nests you have to climb up the cliffs for about 15 meters and then enter a huge cave where the nests are scattered. The birds don't move in the presence of the researchers, probably they don't perceive us as predators! While one of the parents stays with the chick, the other one is out looking for food for 1-2 days. When the chicks are older they are left alone during the day and both parents are out looking for food, and come back only during the night!
