| Calf mortality. Attacks by hyenas on rhino calves in the Salient have been observed at the lodges' salt-licks for many years, although no successful attack has ever been reported. The high percentage of calves showing scars presumably inflicted by hyenas point to predation as a potential factor... |

| In the first two years of their lives mortality is high. Goddard (1966) estimated that there was about a 16% loss, caused by predation by lions and spotted hyaenas or lowered resistance to disease caused by lack of food or water. |

In areas with good grazing and water the home range of individual cows may be as small as 6-8 km? . With deteriorating food sup... |

| Black rhinoceros are not strictly territorial in the sense of defending delimited areas against others of their species, but each adult does tend to remain within a specific home range which may overlap with the home ranges of other members of the population. The size of a bull rhinoceros' home ... |

| The birth rate of the present population was 13.6%, compared to one of 24.1 % reported for the period 1964-1966 by Goddard (1967a). However, during my second visit to the area, a year later (December 1983), five more calves had been born, thus raising the birth rate to 24.2%, a value very close ... |
