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.

The whale song will last up to 30 or so minutes, and will be repeated over and over again over the course of hours or even days. [12] This "Russian doll" hierarchy of sounds suggests a syntactic structure [13] that is more human-like in its complexity than other forms of animal communication like bird songs, which have only linear structure.
