When highly aroused such as during a Mating-Pandemonium, Bonding-Ceremony, or Greeting-Ceremony, elephants may produce highly variable and often overlapping calls types including Rumbles, Revs, Grunts, Trumpets, Roars and Snorts. They also produce combination calls, such as Snort-Trumpets, Trumpet-Rumbles, Rumble-Roar-Rumbles, Rev-Rumbles etc. In addition, elephants may make novel sounds that do not fit into previously defined call types. We include an example of a call that sounds like a short squeal, somewhere between a high pitched Trumpet and a Cry that could have originated either in the trunk or the larynx. As we await other possible examples and or possible classification in an existing call type, we have named it, Squeal-Trumpet.
