Key facts
- Scientists have identified eight fundamental sound types, termed 'motifs', that form the basis of birdsong.
- These motifs include three types of trills, three types of whistles, chaotic notes, and harmonies.
- AI analysis of over 116,000 songs from more than 3,000 species revealed this underlying simplicity.
- Environmental factors, such as tropical forests versus temperate landscapes, influence the combination and use of these motifs.
- Simpler motifs like flat whistles are found in tropical environments, while more complex compositions are common in temperate forests.
Scientists in France have identified the fundamental building blocks of birdsong, revealing that the incredible diversity of avian vocalizations is composed of just eight core sound types, or 'motifs'. The research, which analysed over 116,000 songs from more than 3,000 species using AI, found that these motifs—three types of trills, three types of whistles, chaotic notes, and harmonies—are combined in various ways across the globe.
