Observations of animals' vocal actions can provide important clues about how they communicate and about how they perceive and react to changing situations. Here, analyses of consecutive songs produced by singing humpback whales recorded off the coast of Hawaii revealed that singers constantly vary the acoustic qualities of their songs within prolonged song sessions. Unlike the progressive changes in song structure that singing humpback whales make across months and years, intra-individual…

Characterizing the rhythm and tempo of sound production by singing whales
TLDR
This work presents an approach to analysing temporal structure within song sessions that can be applied to any recording of a nearby, isolated singer, without requiring subjective classification of songs, themes, phrases or units.
Song copying by humpback whales: themes and variations
TLDR
Analysis of changes over 14 years in the sounds used by humpback whales singing in Hawaiian waters found that although the properties of individual sounds within songs are quite variable over time, the overall distribution of certain acoustic features within the repertoire appears to be stable.
Song Morphing by Humpback Whales: Cultural or Epiphenomenal?
TLDR
Property of song dynamics suggest that singing humpback whales may be modulating song features in response to local conditions and genetic predispositions rather than socially learning novel sound patterns by copying other singers.
Songbird dynamics under the sea: acoustic interactions between humpback whales suggest song mediates male interactions
TLDR
Acoustic interactions of humpback whale singers resemble known mechanisms of mediating intrasexual interactions in songbirds, and changes in song presentation may be used in competition between singing males.
Variability in the temporal parameters in the song of the Bengalese finch (Lonchura striata var. domestica)
TLDR
The results suggest distinct sources of temporal variability exist at multiple levels on the basis of this note–gap relationship, and that song comprised a mixture of these sources.
Large Scale Changes over 19 Years in Songs of Humpback Whales in Bermuda
TLDR
163 songs of humpback whales recorded near Bermuda during April and May of 13 years between 1957 and 1975 have been analysed as continuous sound spectrograms and compared to define a song form which characterizes songs from many years.
Cultural revolutions reduce complexity in the songs of humpback whales
TLDR
The consistent reduction in complexity during song revolutions suggests a potential limit to the social learning capacity of novel material in humpback whales.
Similarities in composition and transformations of songs by humpback whales (Megaptera novaeangliae) over time and space.
TLDR
Evidence of similarities in song structure both across populations and decades that strongly challenge claims that social learning is the main driver of variations in humpback whale songs over time is presented.
Songs of Humpback Whales
1) Humpback whales (Megaptera novaeangliae) produce a series of beautiful and varied sounds for a period of 7 to 30 minutes and then repeat the same series with considerable precision. We call such a
The Organization of Song Repertoires in Song Sparrows: Themes and Variations
TLDR
It is argued that song sparrow songtypes are probabilistic units of song production, and the functional and evolutionary implications of having vocal motor patterns organized in this way are discussed.
