Sexual selection is a mode of natural selection where members of one biological sex choose mates of the other sex to mate with, and compete with members of the same sex for access to members of the opposite sex. In this scenario, female birds choose mates based on the quality of the nests built by male birds, which is a classic example of sexual selection.
