Behavioural measure	Description
Strength of response:
First orientation (s)	Duration of first orientation towards loud speaker
Initial displacement (m)	Maximum distance travelled within 30 s of experiment
Leopard-appropriate response
Arboreal escape	Does subject climb to >2 m within 30 s of experiment
Time arboreal	Is subject >2 m high within the 30 min following experiment
Male-Male competitive response
Initial approach (m)	Distance approached towards loudspeaker 3 min post-experiment
Minimum approach (m)	Minimum distance to loudspeaker within 30 min of experiment
