Common Yellowthroat (Geothlypis trichas)

The male birds with few exceptions have no penis. The mating birds cling and may twist about until the two cloaca are brought together and sperm is transferred to the female.
The cloaca is the posterior opening for a bird's digestive, urinary and reproductive tracts that is used to expel feces and lay eggs.
