Open savannas are the principal habitat during the wet season (approximately 70% of sightings occur in this zone). In the dry season, grass savannas with trees (especially Combretum, Terminalia macroptera, and Detarium) and bushes are preferred (at a similar rate of 70% of sightings). Dense gallery forests are avoided. Historically, population densities of Buffon’s

feeds on grass throughoutthe year, but tends to be less selective during the wet season. Dry season burns coupled with the rains create a flush of new growth at the start of the wet season; grasses like Andropogon africanus, A. gayanus, A. tectorum, Echinochloa colonum, and Brachiaria mutica are favored at this time of year. In the wooded savannas used during the dry season, Hyparrhenia subplumosa, Schizachyrium sanguineum, and Vetiveria fulvibarbis are preferentially consumed; Buffon’s

), formerly occurred in areas where population density exceeded approximately 15 ind/km?; these densities are rare in modern West Africa, and lekking is now uncommon. Breeding males tend to be territorial; females pass freely through territories without any attempt on behalf of the male to prevent their egress. A male will follow an estrous female with his neck stretched forward and head low. Ritualized foreleg kicks (“laufschlag”) are a prelude to mounting. Other reproductive parameters are unknown but are likely similar to those of the

tends to be active throughout the day and night. Diurnal observations of captive animals indicate a peak in foraging from 09:00 h to 11:00 h and from 17:00 h to nightfall. Unusually, these animals were observed to rest and ruminate in the early morning, a time when activity levels among ungulates are often high; whether the animals were using the early hours to warm up after night-time foraging or were expressing an artifact of their captivity is unknown. A more typical period of rest and rumination occurs at midday, from 12:00 h to 15:00 h. Of the daylight activity budget, 43-3% is spent feeding; a similar proportion (38:3%) is spent ruminating. Activity levels, as measured by distances traveled, are higher during the day (average displacement of 2-4 km) than at night (1-9 km). Distances covered tend to be greater during the dry season (December—March) in response to less abundant food resources.

displays a variety of social patterns, from solitary individuals to large herds of 100 animals or more. A documented decline in population numbers has been accompanied by a shift in social organization toward smaller herds and largerterritories. The largest groups are observed during the dry season (December-March), when Buffon’s Kobs travel en masse to drinking sites. These large herds are usually temporary, fragmenting after returning to wooded savanna where most dry season foraging occurs. Large herds also form at the beginning of rainy season (April-July) when the species emerges onto open grasslands. In 1974, the typical group size across the year was estimated to be 20 animals; however, herds of 1-5 animals now account for over 70% of observed groupings. Buffon’s

herds are very flexible: individuals often join or leave, so the composition of any given group is usually different after a five-hour period. Females constitute the majority of individuals in large herds. Males are more solitary, although young males associate in bachelor herds (these male-only herds are largest during the wet season). Solitary Buffon’s Kobs account for a significant proportion of observations. Isolated males are often territorial and exclude other males from their home ranges even when no females are present. Average territory size is between 0-63 km*and 0-92 km* (range 0-36-1-27 km?); this is significantly smaller than the average home range of females (2:

?). In the 1970s, reported territory size was much smaller (0-03-0-13 km?): the disparity is thought to be due to continued declines in population densities. In

, males show territorial tendencies beginning at three years of age, and most (c.90%) adult males maintain a territory. Territorial boundaries are maintained using displays, including a “proud gait” in which the head is held high and erect. Fights are generally rare. As in the related reedbucks (

spp.), distinctive whistles may indicate to other males that a territory is occupied. Males occupy their territories throughout the year and, although they may leave to drink during droughts, the boundaries themselves are not affected by season. Females frequently shift their home rangesin the late wet season (August-November) to take advantage of changing food resources.
