Two or more related (usually adult) females engaging in a sequence of relatively flat, low-pitched, tonal rumbles of moderate intensity and long duration (~5-6 seconds) that have the cadence of a conversation, rising and falling, as first one individual and then another contributes her voice. Additional females may join the initiating individuals. This pattern of Rumbling is most often heard as a series of two or three slightly overlapping or closely adjacent calls followed by a pause before again calling. The interchange may last several minutes or up to an hour. The pattern of vocal exchange has such a cadence of conversation (in particular what sounds like a higher pitch/lower pitch exchanges by different individuals) that we refer to this as a Cadenced-Rumble.
Mama Little E is standing to the left of a tree and Little E is trying to Suckle. A young female approaches from the left and they engage in a Little-Greeting - Head-Raising and Ear-Lifting and Little-Greeting-Rumbles. A third female at the back right joins in the Little-Greeting and we hear her Trumpet-Rumble.
Note that the approaching female touches Little E. After this the Rumbling continues but taking on the tone of Cadenced-Calling. It is not possible to tell how if doing the Cadenced-Rumbling as this type of calling is not associated with clear Ear-Flapping. Several calls take place as the elephants are moving and feeding and as matriarch Grumpy Grandma arrives with the others. (Maasai Mara, Kenya)
