Baby owls are called owlets. More than 150, and possibly as many as 220, species of this bird of prey exist in the world, and owls come in a variety of colors and sizes.
Owl eggs are white and typically spherical. The number of eggs the female lays varies depending on the species and the individual owl. Usually the larger the owl, the fewer eggs she lays. A female lays her eggs over a period of time which may stretch into a few days, but incubation starts with the laying of the first egg. The eggs all hatch at different times. During incubation and until the youngest owlet is able to maintain body temperature, the male brings food to his family.
