Eighteen mockingbird males are recorded in a study area then the biologist and his team make sonogram for each individual and they study song patterns of the mockingbirds. Later they find that syllables are affected by singing of other species of bird; for example: mockingbirds imitate other mating calls and incorporate other species’ songs into theirs. Mockingbird males that have more repertoires portray an advantage to gain territory rank because repertoire has a significant factor in determining the territory size that a male can acquire (Howard 434). Intrasexual competition would be determined by the variation in song patterns and intersexual selection is more concern about rank but since the two have a direct link, mockingbird males that have more song selections gain not only rank but also attraction from the females therefore have reproductive
