This was adopted by early researchers [127] including C.E.G. Bailey who demonstrated its use for studying bird song in 1950. [128] The use of spectrograms to visualize bird song was then adopted by Donald J. Borror [129] and developed further by others including W. H. Thorpe. [130] [131] These visual representations are also called sonograms or ...

The male's song features three distinct sounds reminiscent of chiming bells. The dawn song typically includes 2 to 6 pure, bell-like notes, sometimes interspersed with quieter tones, and can last between 10 and 40 minutes, particularly at dawn and during the breeding season. While singing, the male stretches his neck and fluffs his feathers.
The song is loud, with an impressive range of whistles, trills and gurgles. Its song is particularly noticeable at night because few other birds are singing. This is why its name includes "night" in several languages. Only unpaired males sing regularly at night, and nocturnal song probably serves to attract a mate.
The archosaurian shift from larynx to syrinx must have conferred a selective advantage for crown birds, but the causes for this shift remain unknown. [10] To complicate matters, the syrinx falls into an unusual category of functional evolution: arising from ancestors with a larynx-based sound source, the syrinx contains significant functional overlap with the structure it replaced.
