A book-length synthesis of research on song function, development, neural control and evolution across songbirds, covering playback experiments on territory defence and mate choice alongside developmental and comparative work.
- Studied in
- Passeriformes
- Sample size
- synthesis of the birdsong literature
Song serves two principal functions — repelling rivals and attracting mates — supported by playback and removal experiments. Repertoire size, song complexity and performance correlate with mating success in several species, and calls form a functionally separate category from song.
What it means
The authors' reading, and ours. Where they differ, that difference is the point.
How the authors put it
Birdsong is best understood as a sexually selected signal shaped by both intrasexual competition and female choice, with learning mechanisms varying across taxa.
How NatureHQ reads it
The standard synthesis, and useful mainly for a distinction popular writing ignores. *Song* is the long, learned, usually male, usually seasonal performance studied in all this work. *Calls* are short, largely innate, used by both sexes year-round for alarm, contact and begging. Almost everything said about "birdsong" applies only to the first, and the tendency to hear any bird sound as song is where most confusion starts.
- A synthesis; it inherits the biases of a literature concentrated on temperate northern songbirds.
- Tropical species, female song and duetting are all under-represented in the work reviewed.
- Correlations between repertoire and mating success are largely observational.
