Preliminary observations on the daytime activity patterns of lesser kudu in Tsavo National Park, Kenya*

Free-ranging lesser kudu were observed during the day in Tsavo (East) National Park for periods of up to 12 h and records of activity patterns were obtained. Data grouped into the percentage of animals engaged in feeding, resting, and other activities in each time class show a changing pattern of behaviour through the day. The presence of a biphasic resting rhythm is demonstrated, the initiation and duration of which are variable. Feeding generally predominated in the early morning and late afternoon. Rumination took place during resting periods which were also used for the avoidance of excessive heat stress. Possible factors controlling the phasing of the behaviour seen are discussed.
