Greeting-Rumble
An explosive burst of long (~5-7 seconds) powerful, throaty, highly modulated and overlapping rumbles when members of a social group come together after a period of more prolonged separation. We refer to these calls as Greeting-Rumbles. Typically, participants approach one another face to face and then, when they meet one another, may turn or Pirouette to stand in parallel while Head-Raising, Ear-Lifting, and streaming with Temporin. Audible Rapid-Ear-Flapping may be heard as the calling continues and the participants may Urinate and Defecate, and may engage in Tusk-Clicking, Open-Mouth-to-Open-Mouth, High-Fiving and reciprocal Trunk-to-Mouth. After the initial explosive greeting, an exchange of lower intensity and less modulated Rumbles continues as the greeting proceeds.
