Greater One-Horned Rhino Vocalizations

Greater one-horned rhinos have a range of approximately 10 to 12 different vocalizations that they use to communicate.  These vocalizations include squeaks, honks, bleats and roars.  They are used as contact calls between mothers and offspring or two unrelated individuals, confrontational sounds between individuals engaged in agonistic interactions, and individuals involved in a prolonged chase. 

Visual and tactile signals are also used frequently in greater one-horned rhino communication.  Individuals might spend prolonged periods lying next to each other.  One individual might spend up to ten minutes licking at the skin of another individual.  They might also nuzzle noses or wave and bob their head at one another.

Like all rhino species, greater one-horned rhino communicate a great deal through scent.  Males spray urine to mark their territory and females squirt urine to advertise their reproductive status.  Both sexes defecate in middens and scrape their feet, kicking dung and getting it on their feet.  The dung, as well as scent from the glands on their feet, deposits their scent along paths as they walk.
