State the reproductive adaptation of birds to terrestrial life.

  • Fertilization is internal. This increases chances of success of the process of fertilization.
  • They lay eggs with shells in which the embryo grows with all the nutrients and protection provided.
  • The birds usually incubate their eggs, keeping them at the right temperature for growth of the embryo and protecting them from external harm.
  • They exhibit sexual dimorphism with a well-developed courtship behavior ensuring that mating occurs at the right time.
