What is the birds and the bees?
“The birds and the bees” (sometimes expanded to “the birds, the bees and the butterflies” or “the birds, the bees, the flowers, and the trees”) is an idiomatic expression which refers to courtship and sex, and is usually used in reference to teaching someone, often a young child, about sex and pregnancy. The phrase is evocative of the metaphors and euphemisms often used to avoid speaking openly and technically about the subject.
