Penguins take separation to a whole new level, spending their lives apart with annual visits for mating purposes. After traveling almost 70 miles, once at the mating site, the Penguins search for their mates by bugling call. The males usually remain in one place and lower their heads to their chests in an effort to call out to their female. Having found each other, the two stand breast to breast, bowing and singing to each other before mating. Penguins have no external genitals, and thus the male presses his cloaca (tube) onto hers while she lies flat on the ground allowing sperm to pass through.
