Researchers used AI to study more than 116,000 birdsong recordings from over 3,000 species and discovered that despite their huge variety, birdsongs across the world are built from only eight basic acoustic building blocks
- Songbirds and similar perching birds were studied.
- Birds that live in dense vegetation/forests had less complex songs. Sounds become distorted as they bounce off densely growing trees, so simpler songs allowed the message to remain clear at greater distances and reduced distortion.
- “The eight motifs include three types of trills played at different speeds, three kinds of whistles with different pitch changes and two more complex sounds described as atonal chaotic notes and harmonic stacks.
Most species used more than one motif in their songs. In fact, researchers found that individual songs usually contained between two and eight motifs.
However, one motif often dominated. The researchers found that 65.3% of species used their main motif in more than 80% of their songs.
The remaining 34.7% of species used a wider mix of motifs, resulting in greater variation in their songs.”
