为什么birds and bees在西方文化中用来代指性启蒙教育

"The birds and the bees" is an English-language idiomatic expression and euphemism that refers to courtship and sexual intercourse. The "birds and the bees talk" is generally the event in most children's lives in which the parents explain what sexual relationships are.
According to tradition, the birds and the bees is a metaphorical story sometimes told to children in an attempt to explain the mechanics and good consequences of sexual intercourse through reference to easily observed natural events. For instance, bees carry and deposit pollen into flowers, a visible and easy-to-explain parallel to male fertilisation. Another example, birds lay eggs, a similarly visible and easy-to-explain parallel to female ovulation.
