Black Rhino (bicornis)
When the animal was about 100 m away from us, it stood still and made a loud howling noise through the valley, turned around backwards and walked on. A short time later this was repeated. The reason probably was the presence of another rhino. The observer got the impression that this howling was a sign of anger. Sound: one could take the 'f' on the piano to the right of the key (i.e. from the middle) as upper sound in the form of uuuuuuh, the c under this, but one octave lower, as lower sound in the form of a raw ooooh. The upper uuuuuh, with which the noise began, goes gradually over into the lower c and then again to the upper uuuuh. This fluctuates 4 times, and then end with the normal rhino sound phrrrrr.
