How is the typical song of the male Costa's Hummingbird characterized?

Answer

A series of rapid, high-pitched chips, buzzes, and short warbles

While the visual display is prominent, the vocalizations of the Costa's Hummingbird are also significant for communication. The male's song is not characterized by lengthy, flowing melodies. Instead, it is typically described as a rapid succession of sharp utterances, specifically cataloged as high-pitched chips interspersed with buzzes and short warbles, lacking the sustained melodic quality found in some other bird species.
