How are the ways a trout and s bird undergo fertilization alike an different?

Trout and birds both undergo external fertilization, but they differ in their reproductive strategies. Trout release eggs and sperm into the water simultaneously, where fertilization occurs outside the female's body. In contrast, birds typically have internal fertilization, where the male transfers sperm to the female through copulation before she lays fertilized eggs. While both rely on environmental conditions for successful fertilization, their methods reflect adaptations to their respective habitats.
