Rhinos use several forms of communication.
Due to their solitary nature, scent marking is often used to identify themselves to other black rhinos.
Urine spraying occurs on trees and bushes, around water holes and feeding areas.
Females urine spray more often when receptive for breeding.
Defecation sometimes occurs in the same spot used by different rhinos, such as around feeding stations and watering tracks.
Coming upon these spots, rhinos will smell to see who is in the area and add their own marking.
When presented with adult feces, male and female rhinoceroses respond differently than when they are presented with subadult feces.
The urine and feces of one black rhinoceros helps other black rhinoceroses to determine its age, sex, and identity.
Less commonly they will rub their heads or horns against tree trunks to scent-mark.

The black rhino has powerful tube-shaped ears that can freely rotate in all directions.
This highly developed sense of hearing allows black rhinos to detect sound over vast distances.
