| Sub-adult males and bulls spray-urinated when walking from one station to the other and especially when bulls were courting females.
Bulls spray-urinate more often when courting females than when engaged in other activities. Also when courting, male A was twice observed scraping dung piles very... |

| Owen-Smith (1974) found white rhinoceros bulls to be territorial, although they foray outside their territories to look for water in the dry season. Territorial borders are marked by large hollowed-out dung piles. Ritualized urination is most pronounced when bulls are patrolling the border regi... |

| The ranging pattern of the resident black rhinoceros (Diceros bicornis) in Ngorongoro Crater (Fig. 1), was first studied by Goddard (1967) during the period 1964-1966.At that time there were seventy-eight resident rhinos on the Craterfloor. During the pre |

| Data for range size determination were collected concurrently with those for other studies (Kiwia, 1983) and not systematically. Location points for nine resident rhinos of different sex and age classes were plotted on 1:50,000 maps with grids of 1 x 1 cm, each equivalent to an area of 0.25 km 2... |

| Densities of dung piles in Lerai forest and in the open grassland sample area were 78.5 and 9.3 per km? respectively (Fig. 2a & b). Eighty-two per cent of the piles in the forest and 97% in the grassland were deposited within a meter of the main rhino tracks (Fig. 3a & b). Over 60% of all defae... |

| Habitat quality
The distribution of food, water and shelter also determines range sizes. At the Lerai-Gorigor area where the three resources are close together, the resident rhinos have much smaller ranges compared to the Seneto Plain rhinos, where resources are more widely spaced. This was al... |

| The density of the resident rhinos on the Crater floor in 1982 was 0.06 km - 2 a decline of 80.6% since 1966. Table 3 shows that adult rhinos in this study occupy larger ranges than in the previous study, suggesting that adults have increased their range sizes with the decrease in their density.... |

|
| Individual rhinos were identified using methods described by Klingel & Klingel (1966), Goddard (1966) and Mukinya (1973, 1976). Individuals were classified as adults, sub-adults or calves to accord with the technique used by Goddard (1967). |
