I consider what writers say about the kingfisher, little birds who build their nests on the beach near the sea. They build in a circular form and so tightly compressed that the seawater cannot penetrate the nest. Above is an opening from which they receive air. Here, these graceful little birds place their young ones, so that when the sea comes upon them by surprise, they can swim with confidence and float on the waves without being filled with water or submerging. And the air they breathe through that opening serves as a counter-balance so that those little balls of fluff are not overturned.
