Like humans, chimpanzees scream when they are
being chased, beaten, or otherwise attacked or threatened. These screams
often sound disquietingly similar to human screams .
Female chimpanzees often produce a "copulation
scream" during or right after mating. This copulation scream is
from Nile , a young female who immigrated into the community in 1997.
Young chimpanzees may whimper when nervous or
separated from their mother. The whimper is the call most people associate
with chimpanzees, since most of the chimpanzees we see on television
or in the movies are nervous juveniles. The whimper I've included
here is from a young female, Kilimi, whimpering to her mother, Outamba
. Kilimi's whimpers grade into more intense calls towards
the end.
The "hoo" is similar to a whimper,
and is often given either by juveniles or their mothers to maintain
contact. An adult female, Tongo, produced this series of hoos as her
friend Outamba approached .
When another chimpanzee is being attacked, bystanders often comment
by giving "waa-barks." In this recording of Stocky's
screams, we can hear the short, sharp waa-barks given by someone watching
him get beat up .
