Rumbles, Roars, Trumpets, and Snorts associated with elephant Bonding-Ceremonies. Elephants are highly expressive, demonstrative animals, and they may vocalize loudly and in chorus under a wide variety of different circumstances. Behavior similar to the Greeting-Ceremony may occur following the birth of an elephant, a mating (Mating-Pandemonium), the rescue of a calf, an aggressive interaction with another group, when the group feels threatened, or when close associates are reunited.
