Do birds have sex

Parents have supposedly explained human reproduction to children in terms of the birds and the bees; if birds were really used to make this explanation, it would be widely believed that fertilization occurs after the briefest period of proximity of the waste elimination organs. Most birds do not have external sex organs, according to ''Ornithology,'' a manual by Frank B. Gill W. The transfer of sperm from male to female usually takes place while the male bird is standing or treading on the female's back. The male twists his tail under that of the female so that the opening of the male bird's cloaca, or waste storage chamber, is close to that of the female's. Sperm transfer takes place when both cloacae open outward.

How Do Birds Mate - Courtship and Sex in Birds

Geoff R. MacFarlane, Simon P. Blomberg, Gisela Kaplan, Lesley J. We report the findings of a phylogenetic comparative analysis examining patterns and frequency of occurrence of same-sex courtship and mounting behavior in birds. Our analysis has shown associations between same-sex sexual behavior and both mating system and degree of precociousness at hatching. The patterns of expression and frequency of occurrence of same-sex sexual behavior differed markedly for males and females. Patterns of same-sex sexual expression reflected the competitive sexes that actively solicit sexual interactions in heterosexual encounters.

Q & A; Avian Intercourse

Spring is the breeding season for most birds, but how do birds mate? Coming together in sexual copulation is essential to fertilize eggs to raise young birds, but the sex act is only a brief part of the courtship and pair bonds between birds. Most birds do not have the same reproductive body parts as mammals. Instead, both male and female birds have a cloaca. This opening also called the vent serves as the bodily exit for their digestive, urinary, and reproductive systems.

Sure, birds can fly, but how do they have sex? Can they do it in the air? And where do they keep their reproductive organs? For humans to understand bird sex, they must first throw out all thoughts of mammalian sex organs. Unlike mammals, most male birds don't have penises.
