Species
Rhesus macaque
Dense social signalling with rapid facial expressions, where the value is in the interaction structure rather than any single call.
Wild species
- • Do not feed, approach or make direct eye contact with wild macaques. A direct stare is a threat signal.
- • Do not display food or reflective objects near a troop.
- • Macaques can transmit serious zoonotic disease. Any bite or scratch needs immediate medical attention.

Capture note
Coos, grunts and screams span a wide band and are well captured by consumer microphones. Troop settings almost always contain overlapping callers, which the source-separation stage flags.
Signature signals
What an experienced observer looks for in this species.
Bared-teeth display
videoUsually appeasement or submission, not aggression.
Coo call
audioTonal contact call used to maintain troop cohesion.
Open-mouth threat
videoTeeth covered, direct stare — a threat, unlike the bared-teeth display.

Body-language channels
Only these are weighed for this species.
Limitations
- • Troop acoustics overlap heavily; attributing a call to an individual is often impossible from a single recording.
- • Facial signals are fast and are frequently missed at typical handheld video frame rates.
