Bird eggs get fertilized through a process called copulation, where the male bird transfers sperm to the female. The sperm travels to the ova, where fertilization occurs within the female's reproductive tract before the egg is laid.

FAQs & Answers

  1. How does fertilization occur in bird eggs? Fertilization occurs when the male bird transfers sperm to the female during copulation. The sperm travels to the ova inside the female's reproductive tract where fertilization happens before the egg is laid.
  2. Do all bird eggs get fertilized? No, only eggs that have undergone fertilization inside the female's reproductive tract contain developing embryos. Unfertilized eggs will not develop and are typically laid without embryos.
  3. Can fertilization in birds occur outside the female's body? No, fertilization in birds occurs internally within the female reproductive tract before the egg is laid.
