Thin lines = rivers; dashed-stippled lines = streets and roads; thick and dashed lines = boundaries of vegetation; large black dots = towns and villages. Vegetation: wide hatched area = mountain forest of high altitude with Arundinaria alpina; narrow hatched area (P) = mountain forest of high altitude with Podocarpus division; narrow stippled (D) = mountain forest of middle altitude with Drypotes division; wide stippled = mountain forest of low altitude with Lebrunia bushaie, etc.; areas with small hooks = swamps with Cyperus latifolius; empty areas (S-K) = savannah with Setaria sphacelata and Kotschya africana. of its exceptional vegetation composition and isola- tion, the study area can be considered a natural habitat of the blue monkeys to which they have successfully adapted. Description of the vegetation and climate conditions have appeared elsewhere (Schlichte, 1975). Methods I started intensive systematic observation in June 1972, but was forced to break off in November of the same year, due to transfer of the program in which the study took place. For quantitative data collection, the monkeys were observed continuously in weekly intervals over a period of 12 hours (from 12 noon to 6 and on the following day from 6 to midday), at a dis- tance of 30 to 50 m (maximum 200 m) by means of binoculars (10 X 40). In addition, protocols of the activities, neighbors, food, and other relevant in- formation were recorded for each visible individual on a cassette recorder every 5 minutes, resulting in 5-minute units for each animal. These units were summarized as needed. For feeding habits, the data for the whole day (12 hours) were added. The fundamenta
