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…
