Vocalization In To Kill A Mockingbird

Vocalization is an essential type of communication for passerine species. Bird is a primary example of using auditory signals between intraspecies and interspecies. This research paper will examine the European warblers, mockingbirds and sparrows to show that songs are specifically developed by male birds in order to attract females and they are also the way for females to evaluate potential mates to ensure reproduction success. Vocalization is also a mechanism used by this taxon to be able to alert others of potential predators by producing alarm and mobbing calls, studies about risk perception in forest birds and black-capped chickadees would be able to evaluate the accuracy of this statement; another interesting use of alarm call is how it is a tool for bird to not only protect their population, but also to increase individual fitness and fight off intraspecie competition when it comes to food sources, we would examine this by looking at a …show more content…
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
