The Rumbling and Trumpeting by adult, adolescent and juvenile females that is associated with the building of a Coalition. Due to the overlapping nature of the Rumbles and the relatively few recorded examples, it is not known whether these calls are specific to Coalitions or whether they are more generally associated with bonding behavior. The term Coalition-Rumble or Coalition-Calling is merely a term used to distinguish the context in which the vocalizing occurred.
