Orangutan Communication Reveals Unexpected Complexity

New research employing AI and traditional methods uncovers a diverse array of vocal patterns in Bornean orangutans.

Scientists identified three distinct pulse types in orangutan long calls through a combination of human and machine analysis.
The study recorded hundreds of calls from 13 orangutans over three years, breaking them into over a thousand 'pulses.'
Machine learning and traditional methods were used to analyze the calls, revealing a greater variety of sounds than previously known.
The findings highlight the intricate vocal systems of orangutans and suggest a broader complexity in animal communication.
Researchers hope the study will inspire further exploration of vocal complexity in other species.
