How do male birds fertilize eggs?

During mating, the male bird goes on top of the female, facing the same direction. They have an entrance called cloaca which they rub against each other. From the cloaca, the male sperm passes onto the female ova, where it is fertilized. After fertilization, the egg comes out of the female cloaca.
