Pant-grunts and pant-barks are submissive calls, given when approaching
or being approached by higher-ranking individuals

.
Pant-grunts often grade into pant-barks
and pant-screams
.
I've included a grunt by Outamba's infant daughter,
Tenkere
.
Babies riding on their mother's belly often join the
pant-grunts their mother makes when approaching high-ranking chimpanzees.
